The Vanishing Corpse is a 1941 mystery thriller novel by Anthony Gilbert, the pen name of British writer Lucy Beatrice Malleson.

It is the eighth in her long-running series featuring the unscrupulous London solicitor Arthur Crook, one of the more unorthodox detectives of the Golden Age.

He suggests that she is now in grave danger from the murderer and persuades her to move to a large, busy hotel in Brighton where she will be safer.

Newspaper publicity at last draws the police into the case, and with Crook's advice they find a body hidden in the well of the cottage.

In 1943 it was very loosely adapted into the British film They Met in the Dark directed by Carl Lamac and starring James Mason, Joyce Howard, Tom Walls.
