THE CASE OF THE RUNAWAY CORPSE- Erle Stanley Gardner

Her husband was stealing her money, while accusing her of a plot to poison him – or so claims the frightened young Mrs. Myrna Davenport. She wants Perry Mason to find the incriminating note her husband left for the authorities accusing her of murder – especially now that Davenport is dying.

Perry finds the envelope, but it’s filled with blank paper. Then Davenport does die, or so everyone thinks until his alleged corpse climbs out a window and drives away-straight into a prepared open grave in another country.

With Davenport finally dead, Perry could become a possible accessory to murder. And thought the victim died twice, Perry gets only one clear shot at saving his client – and himself.
