This is the sixth of the Whistler films. Once again Richard Dix stars, this time as an impecunious artist who has married a very rich woman. The versatility of Dix really is astonishing. He changes like a chameleon from picture to picture. This film is not directed by William Castle like the others, but by George Sherman. It has a completely different feel about it. It is not so quirky and mysterious, but is more of a glamorous melodrama. The budget seems to have been a bit higher, and the film is more of an ordinary murder mystery. The film opens well with a woman going to a monument maker and commissioning a very expensive gravestone for herself. ($5000, a lot of money then.) She is Dix's wife. She has a severe heart condition and believes she has only months to live. Dix is a dutiful husband towards his wife, seriously concerned for her health, until he falls into the clutches of a scheming young femme fatale played by Leslie Brooks. This curvaceous blonde artist's model sees dollar signs and goes for Dix bigtime. He naturally becomes infatuated and says when he is free (i.e., when his wife has died) he wants to marry her. But then along comes a clever doctor with a new treatment which restores the wife to health very suddenly. She overhears Dix and the blonde talking and realizes the situation, so phones her lawyer to arrange to change her will so that he inherits nothing whenever she does die, and to commence divorce proceedings immediately. However, this is a film noir, so she dies during the night. So what has happened? "The Whistler knows."
