They are hired to solve a massive theft crime. How can a valuable heirloom ring dating back to Napoleon be stolen from a secure vault behind hidden passageways in a chateau? Cameras have not identified anyone breaking and entering, so what or who is behind this caper? The suspects appear to be playing games with the detectives, making it appear they are everywhere at once. How many suspects are there? The ending may surprise you.
