[1] Adapted from the 1954 novel of the same title by Erle Stanley Gardner, this episode marked the beginning of Raymond Burr's long-running portrayal of the famous fictional lawyer.

Red-headed waitress Evelyn Bagby (Whitney Blake) comes home to her apartment one night and is shocked to find a revolver, which she'd never seen before, in her cigarette box.

Having once been accused, then acquitted, of stealing jewelry from a famous movie star, Evelyn calls defense attorney Perry Mason (Raymond Burr) to ask for his advice.

Mason goes to the scene of the incident, and finds that the homicide police are already there; the hooded driver was killed by a bullet to the head.

After a great many twists and turns (including Mason using an identical gun to fire two bullets into a tree and a post at the crash site), Mason, with help from private investigator Paul Drake (William Hopper), exposes the true killer in the courtroom; as a result, Evelyn is cleared of all charges.
