Three Detectives: Multi Spyby Thames & Kosmos
The multispy fits into any pocket. During investigations, the crime scene can be examined using a magnifying glass, ruler, and a pair of tweezers. Messages can be encrypted and decrypted using code discs and short messages and passwords can be stashed in the secret compartment for confidentiality. Periscope mirrors, a compass, and a sundial can be very useful when tailing someone.
