Quiet Alibi — Six Case Collection (Intermediate & Hard)

Six cases. Build your theory. Prove it.

Enter a radio studio, a harbour, a tower, a theatre, a polar station and a glasshouse after midnight. Each mystery now has six connected digital chapters: inspect the scene, compare conflicting records, question the people and support your final finding with evidence.

What you will do

Reconstruct a recording from fragments. Correct clocks that disagree. Test every statement in a truth table. Plan a route around closures. Separate payload from disguised packing weight. Challenge an unreliable report. Link the right records to your conclusion rather than merely guessing a name.

Every case includes an illustrated scene with inspection points, 17–20 evidence records, four people to question, a searchable evidence desk, two-record comparison, a notebook and optional hints. Six chapters lead to an evidence-supported report and a choice about how to close the case.

The six investigations

The Glasshouse at Midnight — Hard

A missing specimen, conflicting clocks and an alibi that must stand up to the route evidence.

Dead Air at Station Nine — Hard

A recorded alibi, drifting timestamps and a broadcast whose approval trail matters as much as its contents.

The Tideglass Diversion — Intermediate

A harbour handover, a route constrained by closures and cargo that cannot be judged by its gross weight.

The Ninth-Floor Exchange — Hard

A service-lift route, disguised cargo and a release decision that requires corroboration.

The Last Curtain — Intermediate

A missing score, a playback mistaken for presence and a truth-table safeguard protecting a disputed attribution.

The Whiteout Protocol — Hard

A polar inspection route, unreliable clocks and a fault report whose integrity must be tested before anyone trusts it.

Time and difficulty

45–60 minutes per full case is a design target, not a verified duration. Difficulty labels and timing still need independent human playtesting. Digital pilot edition 3.0, with AI-assisted content. Puzzle logic and app behaviour have been checked; this is not a claim of human playtesting.
