Bertie Bradshaw never set out to become a spy. He never imagined traipsing around war-torn London, solving ciphers, practicing surveillance, and searching for a traitor to the Allied forces.

But when a young woman goes missing, leaving behind a coded notebook, Bertie is determined to solve the mystery.
