Certainly a feast for the eyes and capturing the 1940's to a tee. Foyle's War a new release from Acorn Media, was first broadcast late in 2002 on the ITV network and written by the prolific Anthony Horowitz.
Set at the height of the so called "Phony War" of mid 1940 when the English were convinced that a German invasion was imminent, Foyle is a Detective Chief Superintendent in the police, however he is desperate to be actually doing his bit for the war effort, ie serving on the front line, he soon finds though that there is more than enough crime and murder on the South Coast to keep him busy. 
The first volume contains two stories The German Woman (which sees Foyle investigating the murder of a German woman who has stirred up resentment in a small village) and The White Feather which sees Foyle trying to break a secret Fascist organisation. 
The original working title for the show was the somewhat lacklustre The Blitz Detective and Foyle is actually named after the owner of Foyle's bookshop in London - Christina Foyle.
The productions are very high budget and you can see where the money was spent oozing out of every frame. All in all Foyle's War is definitely a classy edition to the Detective Drama genre.
