    A bobby, I learned , is a British slang word for cop, which itself is a slang word for policeman. In London, they are actually constables who work for Scotland Yard, and one by one, a dozen of them have been bumped off, stabbed to death by a vicious killer. Jewel thief Peter Lawford happens to commit a burglary (stealing a valuable emerald), and in his escape attempt, comes across the body of the latest victim. The necklace is left behind minus the emerald, and the jewel theft and murder are all of a sudden tied together. Lawford cleverly comes up with a way of both finding the killer and getting away with being able to get rid of the emerald and end up with double the profit, not only via the reward, but by the sale of the gem as well.

    While there is definitely some cleverness to this, it takes a while for that to settle in, the first quarter of this film being rather dry and humorless. Lawford does make fun of himself though in a scene where his character breaks into song and he is clearly off key, one of the listeners telling him politely how truly horrible he is. Dawn Addams plays the pretty daughter of the head of Scotland Yard (Michael Hordern) who is grateful to Lawford to coming to her fiancée's rescue. Roland Culver is the other officer whom Lawford turns the tables on after trying to give him a knock-out drug.

    The result of this remake of "The Mystery of Mr. X" is that it isn't at all spooky, eerie, foggy or really even a mystery because you know who's guilty of what, but in the case of the killer, you just don't know why. It isn't dreary, just nothing out of the ordinary.
