Case of the One-Eyed Witness
Erle Stanley Gardner

Good old Perry Mason. If you committed a murder... well, if it LOOKED like you committed murder, you'd really REALLY want him on your side.

...A frantic woman desperate to retain Perry Mason's services suddenly disappears. The only clues are a news clipping about a blackmail case and the combination to a safe. The case is a tangled web involving an eccentric widower, a sexy cigarette girl, a shady real-estate broker, a wife, a lover, and too many loose ends....
