Based on a novel by John Hale, this 1987 film is a cold war spy story with more twists and angles than can be absorbed in a single viewing.
The boundaries between right and wrong are blurred, in this complex plot where co-workers in the secret service are asked to spy on each other, truth-seekers are murdered, and the guilty are kept protected in their luxurious nests.
With an excellent cast that includes James Fox, Nigel Havers, John Gielgud, Felicity Dean, and many top-notch character actors, it's a fast paced hour and 40 minutes; one of my favourite parts is how they manage to get information out of the imprisoned double agent, making him believe that he has escaped.
Also adding a lot to the film is the lovely soundtrack by John Scott.
Michael Caine is powerful as the former spy and bereaved father, who investigates his son's death. Part vulnerable, part tough guy, it's a subtle, touching, and brilliant performance, and its believability makes this intricate thriller a 5 star film.
