Overview
Wartime thriller with film noir elements based on a true story as written in A.P. Scotland's autobiography "The London Cage". The plot has greatly exaggerated the actual events of A.P. Scotland's experiences, including the addition of a fictional love interest.
Reviews
Jack Hawkins wasn't always renowned for the subtlety of his performances, but he does manage that well here. In this quite plausible adaptation of AP Scotland's fact-based book, he portrays a German officer who works his way up the ranks, ultimately to reach staff rank in the Nazi army - whilst passing on secrets to the British for almost 30 years. The direction is suspenseful and it maintains the tension well - especially towards the end. This is rarely seen, nowadays, but is eminently watchable.
