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.

At the beginning of the episode, Frazier and Hoffman are seen witnessing the Trinity Atomic Test. While wearing googles they see the flash of the blast which is followed by the shock wave 6.3 seconds after (yes, I timed it..). Given the stated distance of the bunker from the detonation tower or 10,000 yards, the delay should have been much longer, 26.6 seconds.

During the same scene, about 12 seconds before the detonation , a group men are scene looking out of one of the other portholes without googles, one even using a binoculars. It is possible that that may have looked away at the last minute, but all personnel would have been wearing googles at the time of the test. See more »

Poorly Done
28 September 2013 | by See 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.
