The film was released in America in 1966, when the producers capitalised on Caine's new-found fame and released it with his name above the title.[6]
Plot
Inspector Sparrow is a provincial detective. When crooks accidentally kill a shop cashier while stealing the keys to the jewellery shop where she works, Sparrow takes his annual leave and works on the case unofficially. He successfully tracks down the criminals and turns them over to Scotland Yard.
The Monthly Film Bulletin wrote: "Fairly routine case of crime and punishment in the Edgar Wallace series, with the sudden flashes of imagination that often redeem these purely commercial operations. Some of the minor crooks are quite skilfully drawn, and a starkly staged interview between Sparrow and a billiard-playing informer is conceived with a real flair for the sinister effect. The thrills are predictable, and the climactic rescue couldn't have been better timed if John Wayne were leading the U.S. Cavalry. But Glyn Houston gives a sturdy performance as Sparrow, and the whole thing is diverting enough."[7]
