Der Mann mit dem Glasauge

In the 1969 West German crime film "Der Mann mit dem Glasauge" (also known as "Terror on Half Moon Street"), Inspector Perkins (Horst Tappert) investigates a series of mysterious murders in London, with the first victim found dead in a hotel and a glass eye found in the killer's pocket. A second, high-profile murder takes place at the London Odeon Theater, where a city-famous dancer is poisoned. As Perkins delves deeper into the case, he follows a series of clues that lead him to a billiard club, where a glass eye is required as an admission ticket. With time running out, Perkins must untangle the connections between the two victims to catch the elusive killer.
