No Coffin for the Corpse — Clayton Rawson

A murdered blackmailer haunts a captain of industry When Ross Harte gets into a screaming match with his fiancee's father, millionaire Dudley Wolff, the old man cuts Harte's beloved out of his will. As far as Wolff is concerned, this is an empty threat, because he plans to live forever. He has a team of scientists working to extend his life as long as possible, and should they fail, a renowned psychic will contact him after his death. Wolff is obsessed with death's mysteries, and he is about to get a first-hand look. When a detective attempts to blackmail him, Wolff punches him in the jaw so hard that it stops the crook's heart. Fearing scandal, Wolff and his staff bury the body in the woods. When the dead blackmailer comes back to haunt him, the millionaire is forced to call on Harte and his friend the Great Merlini, conjurer and sleuth, to banish the spirits that have brought death to his door.
