Foyle's War

New three-part series set in the Cold War era. As Foyle returns from a stay in the USA, MI5 agents persuade him to go to their London HQ immediately. Foyle is told that a Soviet spy network called the Eternity Ring is at large in the capital and could involve the distinguished nuclear physicist Professor Michael Fraser.

The disappearance of a Foreign Office official appears to explain the deaths of a number of Russian agents working for British Intelligence. An apprehensive Sam is also now working at MI5 HQ while helping her husband Adam, who is standing as a Labour Party candidate at the Peckham by-election. While on the campaign trail, Adam meets a woman who asks for his help in finding her daughter Evelyn who has been missing for days.

Foyle is told by the head of MI5 that eminent art historian Professor Van Haren is actually a high-ranking Nazi whose real name is Karl Strasser. MI5 are protecting him because he is a valuable intelligence asset, but someone is now trying to kill him and he wants Foyle to investigate, meanwhile Arthur Valentine makes it clear that he neither likes the man nor agrees with the decision to give him a new identity.
