Foyle's war: fur Elise
Foyle must find out if there was a traitor within the SOE after Hilda Pierce is shot in an attempted assassination.
A young man tries to kill Hilda Pierce, saying "This is for Elise." Visiting her in hospital Foyle meets over-bearing Sir Ian Woodhead, now head of MI6, who, during the war, ran SOE with Hilda, sending undercover agents into occupied France. Foyle learns that Elise was the codename of Sophie Corrigan, an agent killed by the Nazis and that the young man is her brother Miles, out to take revenge on those who sent her to die. At the same time Foyle's department is investigating high powered black marketer Damian White, who has dealings with a Russian diplomat and has corrupt policemen on his payroll. A recovering Hilda tells Foyle that nine agents died in France and the SOE believed that a spy, code-named Plato, was responsible. There are three suspects - one of whom is being blackmailed by White into giving him government papers that he sells to the Soviets. Foyle finally unveils the truth, causing terrible consequences for two people.
