From the Casebook: The Search for Dippy - Natural History Museum

The year is 1905 and guests had been invited to a special preview of the newest display at the Natural History Museum - 'Dippy the Diplodocus'. But when the guests arrived the curators were in a panic... something was amiss! A note was found suggesting a crime was going to be committed! Hundreds of guests had to question suspects and track down the culprit before the King and notables arrived for the display's launch the following night. This escape room-like game had guests exploring the Museum after hours while they found clues and interviewed the six suspects, all of whom had something to hide. Which were lying and which were trying to help? The challenge was on!
