1945:- A group of scientists observe the testing of an atomic bomb at Los Alamos in the New Mexico desert. A year later Foyle is approached by Hilda Pierce, now working for MI5. Her boss Sir William Chambers explains that a Russian defector, Gorin, has supplied them with news of the Eternity Ring, a group of Soviet sympathisers bent on betraying Britain's atomic secrets. Sam is now working as a secretary to Professor Fraser, one of the suspects who was present at Los Alamos and Foyle meets up with her, being introduced to Fraser and his colleague Max Hoffman, a Polish communist who escaped Nazi persecution. Both work at Armwell Atomic Research Station. Hoffman connects Sam to Foyle and she is sacked but when uranium is stolen from Armwell and the thief murdered, she joins Foyle in investigating the Eternity Ring - as well as helping husband Adam stand for election as a Labour MP.

Very last scene with Miss Pierce in she asks Foyle to join her in her car. Her hair is bunched in dark curls around her ears, beneath her hat but in the rest of this scene and in all other scenes her hair is straight and pulled back behind her head. See more »

Poorly Done
28 September 2013 | by JohnLeeTSee all my reviews

Badly written, confusing, and most of all charmless continuation of the excellent series of happy memory. The atmosphere, superb writing, and interesting detail seems to have been put aside for some reason. While it is lovely to see Foyle back, this is a drab affair and one can only hope that the two remaining entries are able to get in touch with the elements that made Foyle's War such a favorite. Kitchen is still worth watching and it is clever that his character still requires a driver. The program certainly has possibilities and should be given a chance. It is a shame that the original plan for the series to proceed through WWII was bungled by programming executives so the Cold War is now the setting but this could be fascinating if handled right in the future.
