Gruzzle: The Spy

The doorbell rings... but no one’s there.

A attaché case stands on the porch... but it’s locked with a key.

Lists and codes cover the case... but they’re all meaningless.

Who has left this case on Sergio Marins’ front porch? And why? Is it dangerous? Should Sergio force it open? To find the answers to these questions and more, Sergio has asked for Gruzzle’s expert assistance.

Order The Spy and see if you can help Sergio crack the codes and ciphers on the attaché case, safely open it, and eventually uncover the identity of the person responsible for this mystery!
