How Mystery Scripts Are Designed

Behind murder mystery case design: character bibles, rubric scoring, clue fairness, and why AI suspects still need human-authored truth.

How Mystery Scripts Are Designed · From Page to AI Suspect

Answer Key First

Commercial mysteries start with a solution document: killer, timeline, clue list, weighted score sheet. Dialogue and rooms are built backward so every scene supports fair play.

Character Bibles

Each suspect gets knowable facts, lies they will tell, and topics they dodge. AI roleplay layers improvisation on those fences — actors with boundaries, not blank slates.

Rubric as Contract

Players agree to a scoring contract: these categories matter. Designers tune weights to highlight each case's trick — time for manor poison, space for architectural horror, access for village storms.

Why AI Does Not Replace Authors

Models generate voice; humans generate fairness. Without authored truth, you have fan fiction, not a game. The pipeline mirrors printing character booklets before hosting a dinner.
