Theyused Dark Forces
It is 1943 and secret agent Gregory Sallust parachutes into Nazi Germany. In the company of an ex-Bolshevik General, the two of them join forces with the widow of a German diplomat who is in contact with Allied Intelligence. It is through her that Gregory becomes unwillingly involved with a Black Magician. Sixteen months later they meet again and decide to pool their knowledge of the dark arts, concocting a plan to use occult forces in an attempt to destroy Hitler once and for all.
