There have been a spate of London police murders, the victims always killed by a long knife (which the police know is a sword cane), the murders always taking place in a deserted but successively different part of town, and the police always being notified by the murderer that he will strike beforehand. By his signed notes, the murderer has dubbed himself as X. The police have their first real lead when the latest murder occurs outside the home where the Drayton Diamond was stolen on the same night. The diamond thief is Nick Revel, a suave, confident career thief, and his two accomplices, an insurance clerk named 'Hutch' Hutchinson, and a taxi driver named Joe Palmer. Nick, however, is not Mr. X, but he and his accomplices know they can't pawn the diamond or return the diamond for its insurance money now until Mr. X is caught. When a well known and respected man named Sir Christopher Marche is arrested for the murders on circumstantial evidence, Nick knows the police have the wrong ... Written by Huggo

Perfect timing
12 February 2015 | by (Baltimore MD) – See all my reviews

Modern directors who don't know how to make a movie in less than two hours could take a lesson from this fast-paced 84 minute thriller, shot in 1934. The tale centers on a killer who uses a cane-sword to skewer policemen, warning Scotland Yard of each murder before it occurs. Unfortunately, jewel thief Robert Montgomery happens to be heisting a diamond just as another bobby is slain -- and becomes the principal suspect. The only way he can clear his name is to catch the maniac, pausing from time to time to dally with Elizabeth Allan as the police commissioner's fetching daughter. As the mystery moves crisply along, there are no long tracking shots, lingering looks at people's faces or endless glimpses of scenery. Instead, Montgomery's bonhomie, Allan's saucy appeal, a clever, amusing script and tight editing make Mr. X a pleasure to watch.
