This is a very strange film, the story (a murder and the subsequent investigation) is serious but it is performed with such an air of farce as to be completely ridiculous.
It stars Peter Reynolds as a smug young bounder who murders his rich uncle. He appears to be completely guilty but there is a problem: no bullet.
The crime story is actually quite innovative but the film is so full of ridiculous characters and nonsense it just can't be taken seriously. It does star a young Charles Hawtrey as a detective though which is interesting seeing him in a straight (well in theory) role.
