The two links
The model’s mechanism consists of two links, and both must hold. A scene’s disaster is the specific event that the following sequel reacts to; that sequel’s decision is the specific goal that the following scene pursues. This is the causal chain. Where both links hold, units read as consequences of one another; where either fails, they read as items on a list. The chain can be checked from either end. Forwards, every disaster should leave something for a sequel to absorb and every decision something for a scene to pursue. Backwards, every goal should be traceable to a decision on the page, which is the direction readers themselves travel, since they look for causes more readily than they project consequences.
Compression
The chain says what must happen; compression governs how much room each part gets. This book uses the word in this sense only: the page-space given to a beat should follow the beat’s weight in the story rather than the writer’s default register. The failure is never compression as such. It is compressing or expanding every beat by the same proportion regardless of what it carries. Compression is a dial rather than a virtue: a thriller that folds a sequel into a clause and a novel of consciousness that spends nine pages on a dilemma are both right, and each would be ruined by the other’s setting. What readers detect is inconsistency in the exchange rate. A book that pays a page for a lost umbrella and a paragraph for a lost child has taught the reader that its accounting cannot be trusted.
A compressed sequel many readers will know is in chapter 31 of Mark Twain’s Adventures of Huckleberry Finn (1884). Huck has written to Miss Watson to tell her where her runaway slave Jim is being held, and feels washed clean. Then he finds himself remembering the river: Jim standing his watch as well as his own so that Huck could sleep. He happens to look round and see the paper.
It was a close place. I took it up, and held it in my hand. I was a-trembling, because I’d got to decide, forever, betwixt two things, and I knowed it.
He thinks for a minute, holding his breath, and says to himself, “All right, then, I’ll go to hell”, and tears the letter up. The memory of Jim’s kindness is the dilemma, priced in what each choice would cost rather than argued. A close place, the paper held and the trembling are the reaction, with no emotion named. The decision is executed by the hands, and it generates the next goal, stealing Jim back, without another sentence of motive. The whole sequel fits in a paragraph because the disaster before it is unambiguous: the reader knows what the letter will do. Compression is bought in the previous unit.
Where compression lives
Cutting a sequel rarely compresses it; usually it produces a skipped sequel. The compressive work is done in four smaller places. The first is the verb of the next action: she drove rather than she decided to drive. The second is tense: the pluperfect performs whole sequels, as in by the time she reached the shop she had stopped rehearsing what she would say. The third is the white space at a break, placed after a disaster and before a scene that opens on a new goal, which tells the reader that a sequel occurred. The fourth is a repeated gesture given a new value: if the father has twice hooked a thumb into his cuff before speaking, the same gesture made by someone else after his death is a full sequel without a word of interiority.
Compression has two limits, and they fail differently. Pushed past the point at which a reader can reconstruct what was skipped, a sequel reads as arbitrary rather than fast, and readers report that they “couldn’t follow why she did that” about a book whose events are perfectly clear. Expanded past the point at which new considerations arrive, a sequel stops being a beat and becomes a condition. The difference between that failure and the long sequels of great novels is not length but yield, which the worked analyses measure in Crime and Punishment.
Deferral
A sequel can also be interrupted. A deferred decision is a sequel whose reaction and dilemma are shown and whose decision is withheld past a chapter or section break, to be supplied later. Having watched the weighing, the reader has usually formed a preference, and now wants the decision for two reasons: to know what happens, and to know whether they judged this person rightly. Brooks’s dilatory space explains when this works. Deferral is a tax on desire, and it can only be levied where desire exists, so a chapter that breaks off mid-dilemma before the reader has any stake in the outcome has broken off on nothing. Its one hard condition is that the deferral must be paid. A decision interrupted and never shown, with a later scene assuming a choice was made, is a skipped sequel wearing a deferred one’s excuse. Meir Sternberg’s distinction between suspense (uncertainty about what will happen) and curiosity (uncertainty about what has happened) says how the payment must be made: suspense is paid by an event, curiosity by a disclosure.
Deferral is one of several chain structures, the larger shapes a sequence of pairs can take. Besides the clean chain, in which every decision becomes the next goal in order, the Reference catalogue lists twelve, among them the braided chain, which cross-cuts two chains so that each one’s waiting is spent in the other; the displaced sequel, in which one character’s disaster is registered by another; the sequel-dominant novel; and the chain run backwards, which announces the outcome first. A sequence that is not working is often the right material in the wrong structure, and the useful exercise is substitution: defer one decision in a chain that feels mechanical, or cross-cut a sequel that has stalled, and see what the change reveals.
The hinge: when the grounds for choosing change
The six beats track how a character’s goals change. They say nothing about how the character’s grounds for choosing change, and that is what readers mean by an arc. To resolve a dilemma a character applies a rule about which cost is more bearable (loyalty over legality, the family over the self, the truth over the peace). Call the rule the criterion. Most decisions are made on a criterion the character already holds, so the plot advances and the person does not. At a few points in a well-made novel, sometimes only one, a dilemma is resolved on a criterion the character did not hold before. That point is the hinge: the moment within a sequel, between dilemma and decision, at which the criterion changes while the options may stay the same.
Huck’s All right, then is a hinge. He does not refute his moral training; he accepts its verdict that he will be damned, and chooses Jim anyway, so the old criterion is outranked rather than overturned. This chapter treats the hinge as a property that a decision may or may not have, not as a seventh beat. It is inferred rather than seen on the page; it belongs to the shape of a whole book rather than to the join between two units; and most sequels have none. But a manuscript can pass every test in this chapter for four hundred pages and still prompt the complaint that its protagonist does not change, because the chain is intact and the criterion never moves. The test for that condition is the criterion test in the diagnostic tests, and Arc and Theme (Chapter 12) takes the hinge to the scale of the book, where it is adopted as the point at which an arc is located and rejected as a seventh beat.
