Plot Summary:It's June 1945 and Detective Chief Superintendent Foyle is still on duty as they are unable to find a replacement for him. He's approached by Brigadier Timothy Wilson, his former commanding officer from his own military service in World War I, who is looking for a Russian POW, Ivan Spiakov, who has escaped and is believed to have been seen in the Hastings area. He's described as a troublemaker who fought for the Germans during the war and was due to be deported back to Russia. Foyle's initial inquiries reveals gossip about Russia not being very welcoming to returning POWs. Sam Stewart meanwhile works in nearby Brighton for Sir Leonard Spencer-Jones who has a Russian POW, Nikolai Valyshkin, working for him a gardener. When Nikolai expresses a deathly fear of having to return to Russia, Sir Leonard tries to arrange for him to stay in the UK. When Sir Leonard is shot and Nikolai disappears, DI Milner turns out to be the officer in charge of the case. With Nikolai missing, Foyle and Sam travel to London to check out the Russian House, where most of the escaping POWs seem to be headed, to find out why everyone is so interested in a few POWs.
