Mysterious Intruder

Directed by William Castle, the production features Richard Dix, Barton MacLane and Nina Vale.

A young woman claiming to be Elora Lund shows up at Stillwell's shop, supposedly in answer to his newspaper advertisement.

Stillwell tells her that her mother gave him some "odds and ends" to sell; he discovered something very valuable among them, but refuses to give her any details until he telephones Gale.

Finding Pontos drunk and passed out, he looks around, but just then, Police Detectives Taggart and Burns bang on the door.

When there is a knock on the door, he hides and finds a newspaper clipping indicating that a magnate has offered $100,000 each for two wax cylinder recordings legendary Swedish singer Jenny Lind made shortly before her death.

James Summers, the manager of the apartment building in which Hanson lives, finds her strangled body in her closet.

William Castle (The Tingler/Strait-Jacket/Shanks) directs this low-budget black-and-white enjoyable minor film noir, that comes with a choice narration by the disguised Whistler (Otto Forrest) ...

It has a good performance by Richard Dix as the unscrupulous private detective and a plausible surprise ending.
