Tonight's film is a superb spy thriller based upon actual events in WW2. James Mason stars as Diello, the trusted valet to the British Ambassador to Turkey. Unbeknownst to the ambassador, Diello is not at all satisfied with his position, and has some very definite ideas about how a life of comfort and gentlemanly leisure might be possible... Based upon the real life intelligence op "Operation Cicero." Co-starring Danielle Darrieux and Michael Rennie.
