The Pursuers (1961)

This has something of a television episode look to it, but it's still quite an engaging thriller that follows the efforts of "David" (a rather wooden Francis Matthews) to track down a former Nazi living in London. "Luther" (Cyril Shaps) is living quietly and successfully when he discovers that he is in the firing line. He concludes that a friendship with a Jewish lady might help divert suspicion, so alights on holocaust survivor "Jenny" (Susan Denny) but will this prove sufficient to keep him safe? Will she be duped too? There is never any jeopardy as to the result with this, and the production is rather stage-bound and basic, but the story is quite well written and Shaps - as his character begins to succumb to panic and desperation - is quite effective before a rather rushed denouement. Fans of the BBC wartime sitcom "'Allo 'Allo" might spot Richard Marner in one of his early roles here too.
