The Case of the Howling Dog is a 1934 American mystery film directed by Alan Crosland, based on the 1934 novel of the same name by Erle Stanley Gardner.

Perry explains how Cartwright should word his odd bequest and after receiving a huge retainer fee, gives him a form to fill out and return.

One of Perry's men is assigned to watch Foley's house and sees Lucy drive away with an unknown man.

Later, acting on a hunch when none of the handwriting samples of the three women gathered by his operatives matches the note and the handwritten copy of the telegram, Perry devises a ruse to obtain a page from Lucy's diary of the day after the Cartwrights disappeared.

During the trial, Perry discredits the cab driver's identification of his passenger when he demonstrates that he misidentified Della as Bessie.

Just then, workers excavating the foundation of the garage addition discover the bodies of Cartwright and Evelyn, murdered by Foley.

Perry states that when the howling suddenly stopped, he searched kennels in the area and found one where a man matching Foley's description exchanged the dog for a lookalike.
