In Medias Res and Other Ways to Open a Story

Starting “in the middle of things” means opening with the action already underway and supplying the context later—or never. Horace praised Homer for it, and it’s still the most effective opening there is.

Why it works

Because it creates a debt. The reader walks into a scene they don’t fully understand and keeps reading to settle that information gap. Curiosity does the work that patience would have to do in an opening ab ovo—“from the egg,” from the chronological beginning.

What it asks in return

You still have to deliver the context, only spread out and in motion. If you dump it all at once three pages later in an explanatory paragraph, you’ve traded one problem for another: that’s an infodump, and it stands out even more because it follows a lively scene.

Other openings that work

• The line that makes a promise. “Many years later, as he faced the firing squad…” (One Hundred Years of Solitude). There’s no action yet, but a debt has been taken on.
• The odd detail. An object or gesture out of place that forces the question why.
• The voice. When the narrator is so distinctive that hearing them talk is enough.
• The ending up front. Reveal the outcome on page one and spend the book explaining it.

The opening that rarely works

The character waking up. The weather. A description of the house before anyone walks in. They’re allowed—some magnificent novels open this way—but they start at a disadvantage: they delay the moment the reader gets a reason to keep going.

Testing openings

Style Optimizer’s Planning section lets you lay out the scenes of a text and move them around, so you can see what happens if that scene from chapter three opens the novel. And when you have several texts, the Brain finds how yours tend to begin: sometimes you discover you’ve been opening the same way for years.

In medias res FAQ

How much can you hide from the reader when you start in medias res?

As much as you like, as long as the scene makes sense at the level of action. Readers will tolerate not knowing who these people are or why they’re there, but they need to understand what’s physically happening. If they can’t follow even that, confusion replaces curiosity and they put the book down.

Is in medias res the same as opening with a flash-forward?

They’re different techniques. In medias res starts at a midpoint in the story and moves forward from there; from that point on, the order stays linear. A flash-forward shows a future moment and then jumps back, which builds a specific expectation about a scene the reader has already glimpsed.

How many pages can you keep the reader going without explaining the context?

It depends on genre and pacing, but as a practical guideline, the first big question should be answered before the end of the first chapter. Stretching the mystery further works in thrillers and demanding literary fiction; in most cases, it breeds fatigue instead of tension.
