Does the generator choose a fixed culprit?
Yes. This version creates one fixed truth and keeps it in a separate GM-only section so the clues and witness accounts can be checked against it.

Mystery & Investigation Generator
Build a case the players can investigate: lock in what really happened, then create suspects, locations, evidence, independent leads and outcomes that agree with that truth. The first version uses a fixed solution and keeps GM-only details separate from player-facing material.

Mystery & Investigation Generator FAQ
Can the players solve the case without one required roll?
The generator is designed to provide multiple independent routes to essential revelations, with clues that state what they support and what they do not prove.
Can I use the case in any role-playing game?
Yes. The generator is system-neutral and supports fantasy, noir, investigative horror, modern and science-fiction settings.
