Trivia
Preview audiences rejected the original ending, where "Nick" did not get "Jane". Retakes and additional scenes were ordered, but directed by Richard Boleslawski because director Edgar Selwyn was unavailable.

Goofs
When Robert Montgomery lists the crime scenes, he says that X always strikes in a deserted area of London. However, one of the crime scenes mentioned is Marble Arch, which is a very busy area in central London. Also, the first murder shown takes place on the bank of the Thames, but none of the crime scenes mentioned is anywhere near the river, and Gates End Lane, the scene of the last murder, is a fictitious street, although the other streets named are real.

Quotes
Jane Frensham: Do you know why I like you?
Nicholas 'Nick' Revel: No, Why?
Jane Frensham: Because you're so straight. I think you're the straightest man I've ever met.

Robert Montgomery as a diamond thief

Robert Montgomery stars with Elizabeth Allen and Lewis Stone in "The Mysterious Mr. X" from 1934.

A serial killer is going around London killing policemen. Unfortunately for Nick Revel and his band of merry men, a taxi driver named Joe and an insurance clerk named Hutch, the killer struck outside a home where the famous Drayton Diamond was stolen. Nick is the thief. But he's not the killer known as "Mr. X," who writes letters to the police just before he strikes. The police think the robber is the killer.

Nick and his cronies know that they can't return the diamond for the insurance reward or pawn it until the serial killer is caught. When a man is arrested, one Sir Christopher March, Nick knows he's the wrong man. He has an idea as to how the police can catch the killer. He figures if he testifies on behalf of March, he will be able to present his plan to the police.

March turns out to be the fiancé of Jane, the daughter of the police commissioner, and Revel and Jane are attracted to one another. Meanwhile, her father is suspicious of Revel.

Pleasant mystery, with a charming performance by Montgomery. Some fun moments, especially when an accomplice delivers the diamond to Revel and drops it in a glass of liquid. The end is quite exciting, with a very dynamic either set or location.

Good movie.
