HOW TO WORK A CASE

A pencil-and-paper mystery.
A desk in your browser.

Read the numbered clues and mark each pairing in the grid: blank, not a match, or a match. Every person has exactly one object and one place. Use the known fact to turn your completed grid into an accusation.

Need a nudge? Every case has three progressive hints and a full answer walkthrough. You can play without saving, or enable “Remember my puzzle progress” in Cookie settings to save each case separately on this device for up to 30 days.
