1946- Whilst working for MI5 Foyle investigates the murder of a professor, William Knowles, who had been a translator at the Nuremberg war trials.
Everything that came over as brilliant on first viewings still are brilliant on re-watches."High Castle" is the first episode of the sadly last season of this wonderful series and while it is a decent episode it's a long way from being one of the best ' Foyle's War' episodes.
Foyle learns not only that Del Mar was recently visited by a high ranking Russian but that Knowles had photographs of German businessmen anxious to trade with Russia for its oil.
He travels to Nuremberg but finds another corpse, a former Nazi factory owner who had dealings with Knowles.
