Choose a practical source of evidence that belongs to the period: a passenger manifest, a household register, a photograph, a rent receipt, or a survey map. Then ask who creates that record and who has the power to alter it. The investigator's work should give them access to details other people overlook. A maid hears a house differently from its owner; an undertaker notices a booking that arrives before anyone has died. Research the setting as you develop the full manuscript, separating an invented town from claims about real historical events. Build the solution before arranging the clues, and make sure the decisive fact could be understood by someone living at the time. Atmosphere can deepen uncertainty, but it should not conceal every part of the explanation. The examples below offer original premises, opening scenes, and ten-beat outlines across several periods. Change the profession, institution, or practical record at the center to create a different investigation while preserving the pleasure of a fair puzzle.
