Seeds from this topic
A woman who has spent her entire career exposing other people's lies discovers that every major memory from her childhood was deliberately fabricated.

Root it
Pick one secret and push it into the character's history until it has a cause.
- How old were they when it happened?
- Who else was there, and where are they now?
- What did keeping it quiet cost them the first year? The fifth?
- What small behaviour did they invent to protect it?
- Who would be destroyed by it — them, or someone they love?
Add pressure
A secret is only a plot once the conditions change.
- Someone new arrives who was also there.
- The secret becomes valuable to a person who doesn't like them.
- Telling the truth would save a stranger and end their own life as they know it.
- A document surfaces that they thought had been destroyed.
- They are asked to publicly condemn exactly what they did.
Cross-pollinate
Give the secret a second person and it becomes a relationship.
- One character knows, and has never mentioned it — why?
- Two characters share the secret but remember it differently.
- The person they are protecting doesn't want to be protected.
- Someone is being blamed for it right now.
Propagate this idea
One secret can grow the rest of the story.
- Secret → who benefits from the silence → a power structure.
- Power structure → a law or custom that makes silence rational → worldbuilding.
- Silence → the character's habits and speech patterns → voice.
- Discovery → the scene you actually want to write → your inciting incident.
