This mystery thriller is set in England during the Nazi Blitz attack in 1940. The book is a sequel to Battlelines but can be read on its own. Two Scotland Yard detectives and a woman from Military Intelligence work to solve a mysterious murder and in doing so come across a Nazi spy plot.

The Nazis have sent in an agent to work with the head of the pro-German movement in England. That head is in charge of a secret mission that threatens the British nation. The detectives have only a limited time to discover the identity of the pro-German head in London.

Additionally, the fate of a refugee child is at stake for one of the detectives. And there remains the possibility of romance in the dark nights filled with German bombs and British deaths.
