Creature with the Blue Hand

Committed to an asylum after the family gardener is murdered, aristocrat Dave Emerson (Klaus Kinski) — who insists he is innocent — escapes the institution and returns to the family castle, where he assumes the identity of his twin brother, Richard (also played by Kinski). The intrigue multiplies when more people are slain, attracting the interest of Scotland Yard snoop Inspektor Craig (Harald Leipnitz) in this scary psychological thriller.
