A downloadable game

A historical key has vanished from a locked display case.

The Grand Bell Hotel is preparing for its anniversary ceremony when the antique Founder’s Key disappears.

Only three people are closely connected to the incident. Each has a reason to look suspicious — but the records, timestamps and witness statements point to one provable solution.

Download the case file, examine the evidence and reconstruct what happened.
