Covering the long year from April 1944 to May 1945, where the end of World War II slowly but inevitably approaches, Foyle and his fellow citizens learn the price of victory and face a peace that will transform their lives in unexpected ways.
April 1944. DS Milner's investigation of a transportation fraud sets in a motion a series of events that brings Foyle back to the force. As Hastings hosts an ecumenical conference on the morality of continued Allied bombing, Foyle probes the suspicious death of a young cartographer from the Air Ministry office.
October 1944. At a psychiatric clinic treating troubled soldiers, the investigation of a doctor's murder turns up no shortage of suspects among the patients and staff. It also complicates Foyle's friendship with Dr. Josef Novak, the Polish refugee who heads the clinic.
May 1945. As all of Britain awaits the formal announcement of the war's end, Foyle reluctantly joins a committee preparing to keep public order during the celebration to come. But the end comes too soon for two men - one a stabbing victim, the other an apparent suicide.
