Masterpiece Mystery!: Foyle's War: The Eternity Ring
Sunday, September 15 at 9:00 p.m.
The first of three all-new dramas finds Foyle investigating the possibility of Russian spies in the heart of London.
With one war ended, a new one is looming as the iron curtain falls across Europe. Suspecting that British atomic research has been infiltrated, MI5 asks Christopher Foyle (Michael Kitchen) to investigate.
During his inquiry, Foyle learns that his former driver, Sam (Honeysuckle Weeks), has been working for one of the possible suspects. Could she be involved?
