A priceless artifact has vanished without a trace from the foggy attic of the museum. Every guard, curator, and visitor in the building that night is a suspect - that's 32,222 people, and one of them is lying straight to your face.
You have 18 clues. An orange backpack that someone left behind. Fingerprints that don't match. A guest list with one name too many. A missed phone call recording with four missing seconds.
Thomas swears he's innocent. Believe him - he's telling the truth. Your job isn't to find who's guilty. It's to eliminate everyone who isn't.
Sharpen your pencil. Follow the clues. Trust nothing. Solve the crime.
