First Published as Fifth Column. September, 1940. As the Blitz takes its nightly toll on London and Hitler prepares his invasion fleet just across the Channel in occupied France, Britain is full of talk about enemy agents. Suspicion is at an all time high and no one is sure who can be trusted. In Canning Town, rescue workers are unsettled when they return to a damaged street and discover a body that shouldn't be there. When closer examination of the corpse reveals death by strangling, Detective Inspector John Jago is called upon to investigate. But few seem to really care about the woman's death - not even her family. As Jago digs deeper he starts to uncover a trail of deception, betrayal, and romantic entanglements.
