Lisbon 1943.

When her cover is blown, Special Operations Executive agent Elisabeth de Mornay flees Paris.  Pursued by the Gestapo she makes her way to Lisbon, where she receives a new identity and a new mission:  to infiltrate – and destroy – a German espionage ring targeting Allied ships.  But to accomplish this, she needs to forge links with the very people who want to see her dead.

And in the City of Spies, no one is who they claim to be.
