Summer, 1944. After almost five years of conflict, London's exhausted inhabitants are living in a world of dereliction. Warweary Detective Inspector Ted Stratton is no exception, but he cannot help being drawn in by his latest case.
Called to investigate when a doctor is found dead, Stratton soon realizes that someone at this hospital is not what they appear to be. Someone has discarded their own identity, and that someone is on a killing spree.
