5 Fingers (1952)

In 1944 neutral Turkey, the valet (James Mason) to the British ambassador (Walter Hampden) is selling secret documents to the Germans for large sums of money. But the Germans are suspicious about the accuracy of the documents, suspecting he might be a British plant. Based on the non fiction book OPERATION CICERO  by Ludwig Carl Moyzisch and directed by Joseph L. Mankiewicz (ALL ABOUT EVE). This is a well crafted spy thriller. The film eschews action pieces and heroics instead concentrating on the meticulous day to day existence of an ordinary man taking extraordinary steps. Still, one wishes Mankiewicz could have tossed in at least one thrill or two. Mason gives an impeccable performance. The insistent score is by Bernard Herrmann. With Danielle Darrieux as an impoverished Polish countess who uses Mason to her own end, Michael Rennie, Michael Pate, Konstantin Shayne and Herbert Berghof.
