104 Intermediate Sb Subplot Plot & Beats

Subplot

A smaller storyline woven through the main one.

What it is

A subplot is a second story line inside one book, with its own person who wants something, its own obstacle, and its own settlement. It runs the same machinery as plot, at a smaller scale. The naive picture of a subplot is a small story running beside the big one. A better picture is one more pressure on one person, or one more angle on one question. Nearly every decision you make about a subplot follows from that second picture.

What separates a subplot from a second novel has nothing to do with size. Attachment to the main story decides it. Most definitions leave attachment out. This site's own one-liner, "A smaller storyline woven through the main one", is true and nearly useless, because it describes the finished effect and skips the structural requirement. The requirement is a shared point under pressure, and it comes in two forms. Either the two lines share a person, who now faces two demands with not enough of her to go around, or they share a question, so the book becomes an argument with itself, held from two sides.

Here is the blunt way to find out whether a thread is attached. Call it the lift-out test. Pick a thread. Imagine every scene in it deleted, along with every sentence elsewhere that refers to it. Then ask which parts of the main plot stop working. If the answer is "nothing, the book is just shorter", you do not have a subplot. You may have good writing. You may have your favorite chapter. Readers will skim it anyway, because they can sense that it cannot alter the ending. You have a separate book attached to this one. The readers who finish will call the book baggy, or slow, or unfocused, and all three complaints mean the same thing: they felt material that could not affect the ending. If the answer sounds like "the protagonist has nothing to lose in act three", or "the antagonist's leverage disappears", or "the ending happens for no reason", the thread is holding the book up. You have a true subplot. The test is blunt on purpose. Run it on the thread you love most, because affection is not function. The dramatic question page asks the same thing from the other end: does this thread make the main answer harder, costlier, or less certain?

A real subplot does at least one of four jobs. Good ones do two or more. The best do three. Whatever the job, the subplot pays for its pages the same way: with a collision with the main plot, timed for the main plot's worst moment. So the rule of thumb is this. A subplot belongs in the book if removing it would force you to rewrite the main plot. It earns its place by colliding with the main plot at the point of highest pressure.

The first job is theme in a second voice. One character arguing the theme is a claim. Two people answering the same question differently is an argument, and arguments persuade better than claims. Say your protagonist is a woman who refuses to ask for help. Pair her with a subplot in which somebody asks and is refused, or asks, is helped, and resents it. A personal trait has become a question about the world. Ansen Dibell's chapter "Patterns, mirrors, and echoes" in Plot (Writer's Digest Books, 1988) is built on this idea: the second line's job is to re-ask the central question in a new register, and piling on events is no part of that job. The practical form is one sentence per thread. Ask, what does this one say about the question? A thread that says nothing is a candidate for cutting, however well written. Reassignment often beats cutting. Give the book's central dilemma to whichever character lacks one.

The second job is a second thing to lose. The subplot raises the main plot's cost. Of the four jobs, this one is the most dependable and the least used. Stakes do not rise when you add threats. They rise when one character cares about more things she can lose. Give your detective a brother in jail awaiting trial. Getting the warrant puts the brother's name into a file. Shielding the brother delays the warrant by a week, and the week matters. The investigation has not changed at all. Every scene in it now costs more. The reader holds two breakable things, and there are two ways the detective can lose her case where before there was one problem. Think of this as an exchange rate. The job is working when a gain on one line costs something on the other, the warrant against the brother. A subplot that "raises the stakes" while the two lines never trade gives the book two separate sets of stakes, which splits the reader's attention instead of focusing it.

The third job is texture and pace. A single line that only ever rises cannot carry forty thousand words. It repeats itself, or it reaches its climax with a third of the book still to go. Two or three lines can be staggered, one peaking while another rebuilds, so the book varies without any line having to restart. Texture alone is the weakest of the four jobs. A thread whose only purpose is contrast owes the main plot nothing, and debt-free threads get abandoned somewhere around chapter twenty-two. The rising action page has the timing math for staggering lines.

The fourth job is the honest reversal. This one is the subtlest, and experienced writers use subplots for it most deliberately. A main plot can only make the turns its own chain of cause and effect permits. Sometimes the protagonist has to be exposed, or lose an ally, or learn something, and there is no fair route to it inside the main plot. The subplot carries the information or the messenger. Because two hundred pages of the subplot's own logic come before that moment, nobody can say you invented it on the spot. The word honest carries weight here. There is a bright line: cost and reveal are allowed, and solve is forbidden. A romance that defeats the antagonist, a mentor's side story that yields the weapon, a sister's thread that supplies the alibi at minute ninety: all three read as a politer deus ex machina, which is a rescue from nowhere. In the finale the subplot's task is to price the victory, never to deliver it. The cause and effect page explains how readers punish a subplot that solves the plot.

Now the heart of the matter, and the part most drafts miss. A subplot justifies itself by crossing the main plot at peak pressure. Running in parallel does not qualify. Keeping a pleasant tone does not qualify. The timing is the main plot's worst hour. The content is a demand that cannot coexist with the main plot's demand. The strongest collision is a forced choice. The protagonist cannot serve both lines, so she surrenders one of them in a written scene, while the reader watches her decide. Nothing in a story is denser than that: a single decision with two separate buildups behind it, two hundred pages each. Books that collide feel dense rather than long. Books with parallel threads feel long rather than dense, at the same word count.

You build a collision backward, in five steps. First, find the main plot's worst moment, which is usually the all is lost beat, and otherwise the chapter before the climax. Second, ask what the subplot could demand at that moment, not only reveal: a deadline, a hearing, a phone call, a person on a doorstep, a favor coming due. Third, make the two demands incompatible, physically or morally. The simplest device is a clock, two things at once in different places. A better device is something both lines need and cannot share, money, a signature, a witness, somebody's trust, so the choice is about more than geography. Fourth, set up the obligation early. The debt must start building in the first third. Planted in chapter thirty, a collision is a coincidence. Planted in chapter six, it is a trap springing shut. The foreshadowing page covers planting. Fifth, make her choose, and make it cost. If she can achieve both, you have a complication, which is fine, but you do not have a collision.

There is a weaker pattern that is also fair. Call it the commenting subplot. It runs in parallel and barely or never touches the events of the main plot. Its effect is on the reader's understanding: a thematic mirror, a double, the other person this might have happened to. Mrs Dalloway is the classic case, and you will meet it below. In exchange for its freedom from events, a commenting subplot has to meet two conditions. It must clearly be about the same question. And its writing and emotional life must equal the main line's, because there is no plot leverage held in reserve. Drafts usually fall short on the second condition, not the first. A page that taught only the forced choice would send writers off to butcher books that do not need it, so keep both patterns in mind.

Six shapes cover nearly every subplot you will write, and each one fails in its own way.

A secondary character's own arc means someone in the supporting cast pursues a want of their own across the book. This kind gives you the most to work with, because the want exists and the character is already on the page. The first risk is promotion by accident. A secondary arc that turns out better than the main one quietly piles up scenes, and you end up with two protagonists and no spine. The second risk is smaller and more common. You run out of room, so the arc gets wrapped up by summary, offstage, in a line of dialogue somewhere around chapter thirty-one.

A relationship, whether a strained marriage, a sibling, a friendship, or a romance, is the commonest kind in every genre, and the romance gets its own treatment further down. The risk is inertia. Writing a relationship is pleasant and requires no obstacle, which makes it the thread most easily dragged two hundred pages with nothing in jeopardy. When the only obstacle is how busy the plot keeps everyone, no subplot exists.

A mystery within the story, such as who sent the letter, what is in the locked room, or why the housekeeper lies, is strong at carrying readers across a slow middle. It carries two risks. Readers who are busy solving are not feeling, so an emotional climax with a mystery running under it goes flat. And it competes for the big reveal. Readers often remember a good minor mystery best of all, which is awkward when the main turn was meant to be the one that lands. The one question to settle is where the minor answer is allowed to land. Planting, turning, and misdirecting belong to the foreshadowing, plot twist, and red herring pages.

A professional or institutional thread, meaning a job, a department, an inquiry, a guild, or a committee, gives texture and authority at little cost, and it is the usual way a second faction's interest enters the book without crowding the main plot. The risk is that procedure is not story. An institution acting with nobody who wants anything enough to break a rule reads as research. The fix is one named person inside the institution whose want clashes with the protagonist's. A thread left as pure process is the first thing a developmental editor, the big-picture editor, circles.

A comic-relief B-plot, a running joke, the broken elevator, the neighbor's dog, a colleague's disastrous dating life, is truly useful. It shifts the tone and gives breathing room between bad hours. In a long, dark book, it is sometimes what keeps the reader going at all. The risk is that it weighs nothing structurally. It carries no debt, so it is the first thread forgotten and the last one missed. The fix costs almost nothing and is nearly always available: one small debt, due at a serious moment. The elevator matters once, on the night that counts.

A thematic mirror means another character or household faces the identical dilemma and answers it differently. This kind is powerful and does a lot in little space. The risk is that your hand shows. A mirror whose whole purpose is reflection reads as arranged, and once readers sense the arrangement, their belief in the main plot goes with it. The cure is a mirror character with an independent want, pursued for its own sake, who could not care less about illustrating anything.

How many subplots should a book have? There is no correct number, and whoever offers you one is talking about their own book. There are two hard limits: how much attention a reader has, and how many pages the book has. Threads do not add up. Every active thread competes with the rest for one reader's attention, so a fifth thread does not add a fifth more interest. It takes a slice out of the other four. Page count sets the floor. A thread stays warm only by recurring, roughly every second or third chapter. Any less often and the reader needs reminding who these people are, and every reminder taxes the main plot a little.

On a finished draft, the weight check takes twenty minutes. For each thread, tally its chapters or scenes and its approximate words, and work out each thread's share of the book. The main plot's share should be above half, and usually well above. A one-fifth share is a big subplot. A one-third share is a co-plot, meaning a second main plot, which is fine only if you chose it knowingly. Then check the final fifteen percent of the book on its own, because nearly all of it belongs to the main plot. A subplot holding a quarter of the final act produces a shared ending, which readers feel as diluted without being able to say why. Check the gaps too. A forty-page hole means a thread has gone cold, and its revival scene will read as a reintroduction. Albert Zuckerman's Writing the Blockbuster Novel, listed below, is the help here. Its chapter "Weaving Plot Strands" treats strand count as an engineering problem rather than a matter of taste, worked out on real outlines, with each strand on its own rising schedule and the peaks offset by design. No two strands peak together unless the author means them to.

When a subplot has quietly become the main plot, treat it as information rather than a fault. It happens constantly. Most drafts, somewhere near forty percent through, try to turn into a different book. Some thread gets interesting, some side character finds a voice, and the writer chases the energy. Either the draft is drifting, or it has discovered something better than the plan. Five signs tell you which, and you can check them in an hour. The writing diary: the scenes you most looked forward to, and wrote fastest, cluster in one thread that is not the main plot. The escalation test: compare each thread's most recent rise, and if the subplot's newest turn outweighs the main plot's, the center of gravity has moved. The ending test: cover the main climax, and if the subplot's resolution alone still reads as an ending, the emotional weight sits there. The description test: ask a beta reader for a two-sentence description of the book without priming them, and if they describe the subplot, that is decisive. Beta readers do this better than you can, because they are not invested in the plan. The word count: the longest thread turns out to be the one you called the subplot.

Then the decision. The question is never "which is better writing". The question is which story the climax can answer and the blurb can promise. Promotion is legitimate, and it is expensive. You move the first plot point earlier, write a climax that answers the promoted story's own question, rebuild the opening to promise it, and write a description that sells it. Demotion costs less. Remove the subplot's two best scenes, transplant its single best line into the main plot, and add one main-plot chapter with real escalation in it. Leaving it undecided never works. You get a climax the book does not care about and an epilogue that will not end.

A subplot typically opens after the main plot and closes before it, and there is a reason for each. It starts later because a reader first has to learn which book this is. Only then can she track a second thread. A weighty thread in chapter one competes with the real opening, and readers fairly assume that the main plot is whichever large storyline arrives first. So the first subplot usually opens in the stretch between the inciting incident and the first plot point, and the second subplot a few chapters after that. Dibell's chapter "Early middles" is about exactly this timing: when to open a new line, and the latest point that still works. Linda Seger, in Making a Good Script Great (the chapter "What Do Subplots Do?" is listed below), gives the rule at both ends: a subplot begun too early gets mistaken for the main story, and one begun too late finds the story over before it can pay off. Each subplot also needs a small inciting incident of its own. A thread that is merely present from chapter four, an existing relationship or an ongoing job, has not started. The start is the disturbance.

It finishes earlier for a structural reason, not a matter of taste. At the climax, attention is at its narrowest and pressure at its highest. A cutaway to settle some other thread lets the pressure fall, and it never climbs back to where it was. Worse is the pile-up: one chapter, three resolutions, none of them felt. The beat page describes the same fault at scene level, and the fix is identical, which is separation. So the default pattern is this. The minor threads shut down one by one on the approach to the climax, and the main question is the last thing to land, with nothing beside it. Each closure, done well, removes something. By the climax the protagonist has fewer allies, fewer options, and no cover left.

Three cases break the rule and work, and none of them is a loophole. In the first, the subplot resolves as the price of the main plot. She wins the case and loses the brother, in one scene, and the loss is what gives the victory its meaning. The subplot resolves inside the climax rather than after it, and no placement is stronger. In the second, the aftermath is part of what the book promised. Family sagas, many literary novels, and most series installments are read partly for the settling. The rule of thumb for a closure after the climax is that it stays brief and reads as the book's final word, never as a second ending. J.R.R. Tolkien's Foreword to the second edition of The Lord of the Rings defends "The Scouring of the Shire" after some readers took it as an allegory of postwar England. He called it "an essential part of the plot, foreseen from the outset". His defense is correct in principle. A late subplot earns its survival by being the consequence the whole book was heading toward. Whether readers accept the defense is a separate question, and the film adaptation left the chapter out. The resolution page treats closing after the climax in depth. In the third case, series fiction, a thread stays open on purpose, which is a different thing from forgetting to close it.

The romance subplot is the commonest subplot in every genre and every market. It has its own conventions and its own typical failures, and it deserves practical help rather than a sneer, because many very good books have one. Start with the contract. The Romance Writers of America definition, which is of long standing, says a romance means a central love story with an emotionally satisfying and optimistic ending. That promise binds a book shelved as romance. A romance subplot inside a thriller sits outside that contract. It may end in death, postponement, refusal, or separation and keep the contract intact. What it may not do is end in nothing. In a standalone book, a relationship left dangling reads as the author forgetting, never as deliberate ambiguity.

Here is the bill a romance subplot has to pay. Finish this sentence: because of the relationship, the main plot becomes harder in that _______. If you cannot finish it, the relationship is decoration. This page covers the join. The love interest page gives the identical test in its own terms, along with the requirement that the partner be a whole person with a life of their own rather than a prize.

There are four joins, from strongest down. The choice: the person against the goal, forced at least once, and best of all at the collision. No bind is tighter. The conflict of interest: the partner is tangled in the main plot through a job, the law, or politics. Maybe the partner is an opponent in it, maybe their fortunes depend on how it ends, maybe the relationship itself is risky because of where they stand. The shared dependency: one scarce thing both lines need, such as time, money, an apartment, or somebody's silence. The hostage: the relationship hands the antagonist leverage over the protagonist. This join is effective and overused, and it is the one most likely to reduce a character to a device. It works only if the person had agency going in.

Six failures account for most bad romance subplots. The romance that simply happens: nothing stands in its way but the plot's schedule, so attraction, then busyness, then eventual availability, for twelve thousand words. A developmental editor circles this first. The love interest as exposition valve: the partner has no plot job, so the relationship becomes a venue where the lead explains the case, and two hundred words of dialogue turn into a briefing. The exposition page covers that symptom. Resolution by rescue: the climax arrives, the partner turns up, and the partner solves the problem, which is the solve-the-main-plot error with a kinder face. The thread with no worst moment: most thriller romance subplots have no low point at all, so give yours one, placed before the main climax, so that the protagonist loses that support for the final act. Heat and tone mismatch: the romance runs hotter than the rest of the book in explicitness, sentiment, or comedy, and reads as if it came from another manuscript, which breaks the reader promise by accident instead of design. The compulsory romance: many excellent novels have none, and if your only reason for including one is that "readers expect one", spend the words elsewhere. A relationship that is itself the main plot follows a different and better-documented structure, which the romance, romancing the beat, and chemistry pages cover together.

Subplots can also cross books. A thread that spans the installments of a series is one of the strongest tools you have if you write several books about the same people. The series page and the series arc page cover the planning. A few points belong here. Writers confuse an unresolved subplot with a sequel hook. Readers never do. An unresolved subplot is carried by this book in earnest: given scenes, escalated, made to matter, and then deliberately left open, usually after advancing one large, visible step. The reader feels invited. A sequel hook is a new question raised only as the book closes: somebody walks in, a letter arrives, a body surfaces. A hook is fair, and it sells books. What fails is a hook substituted for a step. A thread runs three hundred pages, has not moved by the end, and then gets a new dangle. The result is one-star reviews complaining of being strung along. The cliffhanger page warns of the same thing from the other direction. And long-running subplots expire. A will-they-won't-they still unmoved in book seven is no longer a thread. By then it has become a format, and readers notice. Resolving it costs something, because it is the engine bringing some readers back, which is why so many series authors defer the choice until it is no longer theirs to make.

Why it matters

Middles are where books die. The commonest cause is one line of story asked to rise for forty thousand words. A single line can only go up, so it repeats or it peaks early. Two or three lines take turns, and the pressure stays steady with no thread restarting. Better still, a book that moves, in the sense readers mean, is one whose kind of pressure keeps changing. Most of pacing is alternation, and the units you alternate are subplots.

A second thing to lose is the fastest way to raise the stakes. Making the outcome bigger is not the easy route to more reader investment. The easy route is a second losable thing for the protagonist, traded against the first. Of everything a subplot can do, this is the single most useful, and in revision it is nearly free, because the material is usually already in the cast. Somebody on the page has a want that can be tied to the protagonist's cost. The quickest way to find that person is a relationship web. One new line between two strangers on the map gives you a subplot that feels grown in rather than bolted on.

Readers can tell dense from long. Take two ninety-thousand-word novels. One has three threads that collide. The other has three threads that run in parallel. Readers describe them in completely different words: gripping, layered, and unputdownable for the first; slow, ambitious, and in need of an edit for the second. The length is the same. What differs is whether thread can act on thread, and readers register that almost at once, even though they can rarely put it into words.

Reviews name the fault, and the blurb exposes it. This part matters commercially for anyone publishing more than one book a year. Among the commonest specific complaints on competent novels are "Baggy", "too many threads", "the subplot about the sister went nowhere", and "I skimmed the chapters about the brother". All four name the same fault: the ending is not pulled on by that thread. The blurb exposes the same problem from the sales side. A description can carry one situation. Three equal threads force you to pick one, which leaves two-thirds of the book unadvertised. One spine with two supporting threads describes easily. Three spines do not. The structural repair that costs least is usually already in the draft. A thin main plot cannot be cured by adding subplots. Three threads hide a weak spine for fifty pages, and then four things have to land instead of one, so the ending gets harder. But a slack middle on a sound main plot is very often cured by connecting a thread that is already present, with no new thread at all. In production terms, the choice is several scenes versus a rewrite.

Revision is where this element pays most. Writers rarely arrive at subplots at the planning stage. They arrive with a finished draft and a nagging loose middle. Of everything in a manuscript, subplots are the easiest to audit. An afternoon is enough to list, count, measure, and test them, and the findings are among the clearest a draft gives up. Zero contacts between a thread and the main plot is a finding, never a matter of opinion. So the audit belongs in your regular revision routine, and why Try it yourself below is written as a procedure.

Real-world examples

Die Hard (1988): three subplots, three different jobs

Die Hard (1988), directed by John McTiernan and written for the screen by Jeb Stuart and Steven E. de Souza from Roderick Thorp's 1979 novel Nothing Lasts Forever, makes a better example here than any novel, for two reasons. The whole structure fits in two hours, and nearly everyone has seen it. The film seems indifferent to anyone's inner life, yet its structure is made almost wholly of subplot joins.

The main plot is simple. Armed men seize a Los Angeles tower with an off-duty New York cop inside, and he has to defeat them and rescue his estranged wife. Around that main plot run at least three secondary lines, and each does a different job.

Sergeant Al Powell is the LAPD officer on the radio. He is a relationship subplot and a thematic mirror at the same time. He carries an old injury of his own: he once shot a thirteen-year-old boy who was holding a toy gun, and he has not fired his weapon since then. Powell's thread is a complete second story about a man who cannot do what his job requires, and it is about the film's question rather than its plot. At the climax, with the main antagonist already dead, a surviving gunman ambushes the hero and his wife, and Powell shoots him. The thread resolves inside the climax. It settles a debt the main plot owes without solving the main plot's problem. Powell does not defeat the villain. At the moment it is needed, he gets past his own flaw. No subplot placement is stronger, and it costs the main plot nothing.

Richard Thornburg is the television reporter, and he is comic relief that turns deadly. For most of the film he is a satirical pest, played for contempt and laughs. Then his broadcast shows the hero's children. The chief antagonist, watching it, works out which hostage is married to the cop, and the wife becomes a lever. A texture thread has collided with the main plot at peak pressure, and the third act now costs more. No clearer demonstration exists that a comic thread can carry weight: one debt, falling due once, at the worst hour.

The deputy chief, who stands outside the building, is the institutional thread, and he is the weakest of the three, which is instructive. His function is to be wrong, to get in the way, and to stand for an officialdom the hero cannot lean on. He comments. He raises no cost. He is the thread nobody quotes afterward, and he marks the ceiling for an institutional subplot in which no individual wants anything personal.

None of the three solves the hero's problem, and two of them end within the climax or just ahead of it. The film's smallest thread, the limousine driver down in the basement, has a single job, performed in the last two minutes. The lesson is about placement rather than scene craft. Keep a thread that carries one small debt. Drop one that carries none. The scene and sequel page covers reaction beats, and the Powell radio exchanges are its example of them.

Mrs Dalloway (1925): a thread tied on by question rather than event

Virginia Woolf's Mrs Dalloway (1925) covers one June day in London: a woman's preparations for her party, and then the party itself. Beside Clarissa's thread runs the thread of Septimus Warren Smith, a shell-shocked veteran, in the same city on the same day. He is seen by doctors, who do not believe him, and he kills himself. The two never meet. None of this page's collision machinery is present. There is no crossing, no forced choice, and no trade between the lines. The thread fails the lift-out test outright: remove it and the party goes ahead regardless.

Yet nearly everyone who has read the novel would keep it. Its attachment is by question rather than by event. Clarissa's day asks what a life costs when it is lived wholly inside the choices available to it. Septimus's day asks what becomes of someone those choices cannot hold. Woolf's own design was open about this. In her introduction to the 1928 Modern Library edition, listed below, she wrote that Septimus "had no existence" in the first version. Her first plan had Mrs. Dalloway killing herself, or perhaps simply dying, when the party ended. The double was a later addition, and it inherited the function the suicide was going to serve.

Here the commenting subplot works at full power, and it meets both conditions. The two threads are plainly about the same question, and the writing in the second equals the writing in the first. Septimus exists as a person, never as an illustration of theme. He has a wife, a doctor, a tree he looks at, and one terrible afternoon. There is a single, tiny, late point of contact. At the party a guest mentions to Clarissa, in passing, that a young man has died. An entire book of thread exists to make that one sentence land. Such economy is nothing like the forced choice's, and it is harder.

The lesson for a working novelist is not "do this". The pattern is permitted on a condition. Woolf's license to give half a novel to a thread that has no effect on events rests on that thread being extraordinary. A thread that merely runs alongside competently reads as padding, and citing Mrs Dalloway to defend such a thread mistakes permission for ability.

I Have Some Questions for You (2023): a subplot that strips the protagonist of certainty

Rebecca Makkai's I Have Some Questions for You, published by Viking in February 2023, shows the honest reversal and the second thing to lose working together. Bodie Kane, a film professor and podcaster, goes back in 2018 to teach a short course at Granby, her old boarding school in New Hampshire. In 1995, her final year there, her roommate Thalia Keith was murdered. Omar Evans, the school's young athletic trainer, confessed under interrogation, withdrew the confession, and was convicted. Bodie believes him innocent. Her students reopen the case, and so does she.

The main subplot has nothing to do with the school. Bodie's husband Jerome is accused in public by a younger artist of predatory behavior in a relationship from years before. Bodie is fluent on the internet and hosts a podcast about women abused in early Hollywood, and none of that stops her making things worse for herself while she defends him.

Structurally, the thread does the second and fourth jobs at once, with almost no contact at the level of events. It raises the cost. It strips Bodie of her marriage, her professional footing, and most of all her certainty, at the very point where the main plot requires her to be certain about a confession twenty-three years old. And it supplies a reversal the main plot could not supply fairly. Underneath, the book asks how certain anybody can be of a story told about a man. The main plot can only offer one side of that question, since Bodie holds Omar innocent. The subplot supplies the other side. Now Bodie is the one judging whom to believe, and her own memory, it turns out, has shifted. That took an accusation inside her own marriage, with no connection to Granby.

Notice what the thread does not do. It yields no evidence, no witness, no alibi, and no confession. Its effect is on the protagonist's capacity for belief, and solving the case stays with the case. If you ever wonder what a subplot is permitted to contribute at the end of a book, this is the model to study.

The novel also shows, more clearly than anywhere, why the commenting pattern is risky. The subplot's contact with the main plot runs through the narrator's judgment and hardly at all through events, and that setup divides readers. Those following the argument rate the thread the sharpest part of the book. Those reading for the murder feel a detour. Both are describing the same structure. That split is the price of building a subplot this way, and you should decide in advance whether you are willing to pay it.

Elly Griffiths's Ruth Galloway novels (2009 to 2023): the series thread that had to end

Elly Griffiths's Ruth Galloway series runs to fifteen titles, published one a year from The Crossing Places (2009) to The Last Remains (2023). Every book holds a self-contained case: a body, an investigation, an answer. The thread that spans the whole series is the relationship between Ruth, a forensic archaeologist, and DCI Harry Nelson, a married policeman. Here is the purest commercial form of the series subplot, and it teaches several lessons at once.

Each installment holds a true subplot rather than a sequel hook. In every book the relationship gets scenes, escalates, advances one real step, and stays open. At the end the case is closed and the relationship is one step further on, which is why readers feel invited rather than strung along.

The thread is a large part of why readers come back, and Griffiths said so plainly in a CrimeReads essay of April 2023, listed below. She called it "an on-going 'will they, won't they' love story", and added, "with the best will in the world, there comes a time when you have to say whether they will or they won't". There you have a working novelist naming the expiry point, where an open thread stops being suspense and becomes a format.

Resolving it cost something real. When she announced the end of the series, she received "an avalanche of messages on social media talking about bereavement and betrayal", and a common line was "I'll never forgive Elly Griffiths". A loved thread's closure brings grief from the readers it brought back, and blame from some of them. That grief is what a loved thread costs at closing, every time. In Griffiths's judgment, dragging it out any longer would have made readers angrier still.

If you plan a series, carry a long thread. The productive question for each book is what step the thread takes, and what the case would lose without that step. The series page covers the planning.

An everyday scenario: a subplot audit on a finished draft

Suppose you have written a crime novel. The draft is complete, 92,000 words. Your protagonist, Marged Mallick, is a council building inspector who refused to certify a refurbished tower block called Ravenlea Court, and she is under pressure to reverse herself. You sense a loose middle but cannot find it. So you run the audit.

List every thread on one sheet. Beside each, write its opening chapter, its closing chapter, and every chapter in which the thread changes Marged's options or obligations in the main plot. Appearing in the same chapter does not count. One thread altering the other does. Your sheet has four columns: Thread, Starts, Ends, and Changes the main plot in.

Ravenlea Court, the main plot, starts in chapter 1 and ends in chapter 38, and its last column reads n/a. Marged's mother has a place in a care home, partly paid for through Councillor Cadogan Tiplady; that thread starts in chapter 5, ends in chapter 36, and changes the main plot in chapters 14, 27, and 33. Pavel Rusnak, Marged's trainee, intends to report a shortcut she took; his thread starts in chapter 9, ends in chapter 31, and changes the main plot in chapters 19 and 31. Maeve Frayne, a structural engineer and Marged's romantic partner, signed off two similar blocks; her thread starts in chapter 7, ends in chapter 40, and changes the main plot in chapter 22. The lift in Marged's office has been out of order for two years; that thread starts in chapter 2, ends never, and changes the main plot never.

Five minutes of arithmetic gives you four findings.

The mother thread is healthy. It begins once the main plot is under way. It has three contacts, one of them in the last third. In chapter 33 Tiplady states the trade outright, the mother's place against condemning the building, and Marged has to choose. You have located the collision, and it is the source of the ending's cost.

The trainee thread does the second job well and the fourth job by accident. Pavel's complaint removes Marged's procedural cover, which is the only fair way to strip her protection before the climax. But its ending in chapter 31 happens offstage: one line of dialogue reports that the complaint has been withdrawn. After costing the protagonist that much, the thread deserves a scene.

The loose thread is the romance. It has the longest run of all, to chapter 40, past the climax, and it touches the main plot once, in chapter 22. Maeve's professional entanglement with the main plot goes unused in the draft. She signed off two similar blocks, so condemning Ravenlea puts her own certificates in doubt. You have a conflict of interest sitting there unused. The fix is two new scenes, not a cut. In the first third, Marged grasps the implication. Before the climax, Maeve asks Marged to hold back. The agreeable thread now exerts pressure of its own, and the finish line is repaired as a by-product: the relationship closes in chapter 36 instead of running two chapters past the ending.

The lift thread touches nothing, ever. But it is funny, it is eight hundred words, and it is a real tonal asset in a bleak book, so there is no automatic verdict. You add one debt. On the night of chapter 33, with a hearing twenty minutes away, the lift is out, and the stairs eat the twenty minutes. The thread now has a reason to exist.

The audit took one afternoon. The repairs are one resolution relocated, one beat added, and three scenes written, in an otherwise sound 92,000-word draft. That ratio is why the pass should be routine.

Try it yourself

This audit is for a finished or nearly finished draft, and it takes an afternoon. You need the manuscript, one sheet of paper or one blank document, and the template below. The last step is the planning version.

  1. List the threads. Put every thread on one sheet, one line each, named in plain words: the mother's care home, the trainee's complaint, the engineer. If a thread needs more than six words to name, you probably have two threads, or none. Line one is the main plot. Fill in one block like this for each thread as you work through the steps.

THREAD: Starts (ch): Ends (ch): Changes the main plot in (ch): Job(s): second voice / second loss / texture / honest reversal Share of book (%): Resolved onstage by: Verdict: connect / compress / cut / promote

  1. Date them. For each thread, write the chapter where it starts, meaning where something disturbs it, not where the people first appear, and the chapter where it ends. If you cannot find an ending, write "never" and move on. A missing ending is a finding. The audit has not failed.
  2. Find the contacts. For each thread, write every chapter in which the thread changes the protagonist's options or obligations in the main plot. Be strict. Appearing in the same chapter does not count, and one character mentioning the other thread does not count. A contact is a subplot event with consequences for what the main plot can do, what it costs, or when it must be done.
  3. Read the counts. Zero contacts means the thread is not a subplot: cut it or connect it. One contact is fragile, so add another. Healthy is two or more, with one of them in the last third. More than five, and you should check that the thread has not turned into a co-plot.
  4. Name the job. Label each thread with its job or jobs from the four: second voice, second loss, texture, honest reversal. Texture only means probation. No job means it is already cut.
  5. Measure the weight. Count chapters and rough words per thread, and work out each thread's share of the book. Give the final fifteen percent its own tally. If the final act is not almost wholly the main plot's, decide on purpose whether that is what you want.
  6. Check the finish line. Flag any thread whose resolution comes after the main climax, and any chapter holding two or more resolutions. Move all but one. The default is minor threads resolved on the approach, with the main question arriving last and alone.
  7. Check who closes them. For each resolution, ask whether it happens onstage, in a scene, through a character the reader knows. Reviews single out resolutions delivered by report, offstage, or by a near-stranger.
  8. Ask the promotion question. Finish this sentence: the thread I most looked forward to writing was _______. If the answer is not the main plot, run the three tests given above for when a subplot has quietly become the main plot: the escalation test, the ending test, and the description test. The decision is yours, not the draft's.
  9. Act, with the least expensive repair that does the job. There are four, from least expensive up. Connect: find an unused tie already in the draft, a person both plots need, a conflict of interest, a shared dependency, then write two scenes to make it live. Connecting is usually the right choice and always the one that costs least. Compress: keep the thread at half its page count and move its best material into main-plot chapters. Cut: remove it, then hunt down and remove every remaining reference, which takes longer than you expect and improves the book more than you expect. Promote: raise it to main plot and pay in full, with a fresh opening, a fresh first plot point, a fresh climax, and a fresh description.
  10. For a plan rather than a draft, run the sheet forward. Start by writing down the main plot's worst moment. Then give each planned subplot one line: what it demands of the protagonist at that hour, and what that demand forces her to sacrifice. If you have no answer, that subplot has not been designed yet.

Common mistakes and misunderstandings

A thread with no contact. Here is the default failure, and every other item on this list is a version of it. The test: list the chapters in which the subplot changes the protagonist's options, costs, or deadline. No entries means you have a second book stapled into this one. Connect it or cut it. Do not keep it because it is good.

Resolving it offstage. Nine chapters go into a thread, and then it gets settled in a line of reported dialogue because the climax needed the pages. Readers feel cheated of a promise, and they are right. The test: pin every resolution to a chapter, a scene, and a person who is present. Anything you cannot pin that closely is happening in summary.

Letting the subplot steal the best scenes. It got your attention because it was new and nothing stood in its way, and now the liveliest chapters belong to a thread the ending does not answer. The test: rank your chapters by how much you enjoyed writing them, and see which thread owns the top five. No sin here. The ranking tells you the book's preferred shape. The call still belongs to you, and you should make it before a reviewer makes it for you.

The pacing patch that gets abandoned. The middle sagged, so a thread went in around chapter eighteen. It had no destination because none was intended, and it dies somewhere in the thirties. The test: write a one-sentence ending for every thread before you draft anything further. A thread whose ending you cannot state is a pacing patch. The better pacing fix is more pressure on the main line.

The dropped thread. This one is forgotten rather than abandoned on purpose: a question raised in chapter six and never mentioned again. Developmental editors find this more often than anything else, and it is invisible in a full read-through, because you know how it was meant to come out. The test: isolate a single thread and read its scenes in order, skipping everything else. Read alone, a thread that disappears, resolves twice, or resolves and then gets contradicted stands out. Read in context, it is nearly invisible.

A thread born because a secondary character got interesting. You enjoyed writing her, so she got a storyline. That happens all the time, and sometimes it is a gift. Vince Gilligan meant to kill Jesse Pinkman at the end of the first season of Breaking Bad. Aaron Paul's performance made it clear early that this would be a colossal mistake, so Gilligan decided deliberately and rebuilt the series around him. The test: does she have a want that touches the protagonist's problem? If yes, you have a real thread, so plan it. If no, contain her within this book and file her as a lead in waiting. The supporting cast page covers containing a character who grows.

Letting the subplot solve the main plot. The romance produces the alibi, the mentor's side story the weapon, the sister's thread the confession. Readers punish this harder than almost anything, because it makes the main plot's two hundred pages of effort pointless after the fact. The test: hide the subplot's last scene and check that the main plot still has its own path to resolution. If it does not, the main plot's work has been handed to the subplot.

A viewpoint for every subplot. A subplot is a story line, and a story line is not a head. Giving each one its own viewpoint is how manuscripts reach nine narrators without anyone deciding to. The strongest subplots often never leave the protagonist's viewpoint, because the cost falls on her. The multi-POV page covers this.

Three subplots on a thin spine. They conceal the weakness for fifty pages, and then the ending gets harder, because four things have to land instead of one. A thin main plot gets fixed where it lives, in the main plot. After that, if you want more weight, a colliding subplot supplies it.

Mistaking more threads for more depth. Threads do not stack. Two colliding threads feel richer than five side by side, and five parallel lines give the reader no center to stand in. Density comes from connection. Count has nothing to do with it.

Spraying the opening with subplots. Three major storylines inside the first four chapters, and the reader cannot tell which book they are holding. Readers give main-plot status to whatever is weighted most heavily first. Get one line up to speed, then open the second.

"Minor" taken to mean small stakes. A subplot's scale may be modest. Its pressure may not. The person living the thread has to care enormously about its stake, whatever that stake is, or the scenes run on nothing. A small want held in a fierce grip is a subplot. A small want held in a mild grip is a pastime.
