The Midnight Diamond

A priceless diamond. Four guests with carefully rehearsed alibis. And a hotel that keeps its own secrets.

You’re invited to investigate.

The Grand Meridian’s private celebration was going perfectly. Then the lights went out. When they returned, the diamond was gone. The doors never opened. Whoever took it is still inside.

Inspect a hotel map, piece together the timeline, follow a receipt, and decode a secret message. Each answer unlocks the next piece of evidence, until one final deduction exposes the truth.
