Foyle is drawn into the world of corrupt Nazi businessmen when a university professor is found cuddled in a London park. When it transpires the victim was working as a translator in Nuremberg, the detective realises there are powerful people trying to conceal secrets from the Second World War. Meanwhile, Sam (Honeysuckle Weeks) volunteers for a risky undercover job, despite being pregnant. Guest stars include John Mahoney (Frasier), Jaime Winstone (Mad Dogs) and Nigel Lindsay (Four Lions).
Foyle's War opens in southern England in the year 1940 - which may seem a strangely remote period in which to place a new detective, but the setting turns out to be a means of adding moral and dramatic depth to the storylines.
Christopher Foyle is a police inspector frustrated at being stuck at home investigating provincial crimes during the second world war.
Honeysuckle Weeks is an inspired choice as Foyle's sidekick, a clergyman's daughter posted from the Women's Royal Army Corps to serve as his driver, and she plays the part with an admirable period style.
