This is one of a series of really great psychological thrillers made in the 1970s this one based on the popular novel by Frederick Forsyth and co-scripted by him. Set in West Germany in 1963 and investigative journalist Peter (Jon Voight) is given the diary of an old man who has committed suicide. The diary reveals the old man was a former inmate of a Nazi extermination camp and had recently seen the former commandant and wanted war criminal Roschmann (Maximilian Schell) walking free in Hamburg. Peter, after reading the horrors outlined in the diary, decides to try and track down Roschmann and his investigation soon finds him the target of a sinister organisation known as Odessa and he becomes of interest to the Israeli intelligence services. This has a good solid story, a twist and turn plot and a neat unforeseen ending. Voight, in one of his first big roles, is perfect as the German struggling to come to terms with the terrible past of his country and the film attempts to delve into the moral issues for modern Germans in dealing with the history of the Holocaust. But at its heart this is a good espionage yarn that is well worth seeking out.
