Case file anatomy
The evidence does not explain itself.
Every object earns its place. Read closely, compare stories, scan only when instructed, and decide which version of events you believe.
- 01
Break the seal
No setup ritual. Empty the envelope onto a table and start with the first marked document.
- 02
Interrogate the evidence
Photographs, handwritten notes, reports, maps, suspect lists, and strange artifacts turn your table into the scene.
- 03
Follow the signal
QR-triggered voicemail, audio, or video reveals another layer without turning the whole experience into screen time.
- 04
Make the call
The ending is not only an answer. Your final decision can alter what waits in the next envelope.
