Who knows what?
And when?

A character can only act on what they know, suspect, or misunderstand at that point in the story. This sounds obvious until you move a reveal or rewrite an earlier conversation. Then a later decision may quietly depend on information the character has not received.

Make a fact, not a vague note

Choose one fact that matters to a decision: “The ledger entry was altered,” for example. Avoid a broad note such as “Mara knows about the mystery.” The smaller fact lets you tell the difference between seeing the ledger, noticing a discrepancy, and understanding who changed it.

Write down the first scene where the fact is available to the reader. Then write down when each important character learns it. Those moments may differ, and the difference can create suspense.

Track the route into each character’s mind

For each person, record whether they saw the evidence, heard it from someone, inferred it, or merely suspect it. A secondhand account can be wrong. An inference can be strong enough to motivate a choice without becoming certainty.

• Which scene gives them the information?
• Who or what is the source?
• Do they believe it, and why?
• What do they still misunderstand?

This is particularly useful for secrets shared in stages. The reader may know the answer while the protagonist has only two clues; another character may be acting on a convincing lie.

Read decisions against the knowledge timeline

Look at every later scene where the fact matters. Does a character ask a question they no longer need to ask? Do they hide something they now know is harmless? Do they name a culprit before the evidence reaches them? A line of dialogue can expose the break, but the deeper problem is often the decision beneath it.

For the ledger example, moving Mara’s discovery earlier might change how she speaks to Tom in the next chapter. She can still avoid confronting him, but the scene now needs a reason: fear, uncertainty, or a plan to test what he knows.

Revise the chain, then read for drama

If the timeline breaks, you can move the discovery back, change who shares it, or rewrite the later choice. Follow the repair through every scene that depends on it. After the factual pass, read the sequence without consulting your notes. The events can be consistent and still feel unconvincing if a character ignores an obvious implication.
