Cold Case Bureau

A new case file lands every morning. Read the witnesses, find the lie, name the killer. 90 cases across four tiers, no ads, no accounts, no nonsense.

Cold Case Bureau is a quiet, paper-and-typewriter mystery game for people who like to read closely and think slowly.

A case file lands on your desk. The summary. The victim. The evidence. The suspects, each with their own story. Read every piece. Watch for the contradictions — the moments when two pieces of evidence can't both be true. Pin them together on your investigation board. When you're ready, submit your findings: the suspect, how they got in, and why.

Get it right and your reputation climbs. Solve enough cases at the rookie tier and the detective files open up. Detective leads to senior. Senior leads to the major cases, the kind that sit in cold storage for years.

Ninety bundled cases. Four difficulty tiers. No internet required.

Your progress stays on your device. The only data that leaves the app is what you write in the optional feedback email. That's it.
