Detective Jefferson Hastings is visiting the home of wealthy and eccentric Arthur Sloane when two guests stumble across a body on the lawn. Sloane’s daughter Lucille asks Hastings to help solve the crime, but Hastings gets surprisingly little help from anyone else -- including Mr. Sloane, and even the mother of the victim! With few clues to aid him and nobody beyond suspicion Hastings must rely on subtle expressions and scant evidence to solve the murder.
