1979 Penguin Books mass market paperback, Patrick Watson (Fasanella's The Paintings of Ralph Fasanella with the Story of his Life and art). Daisy Nelson knew that her husband was dead. She had seen him, cold and mutilated, so he couldn't be facing her across the room. There weren't two Rob Nelsons. Or were there? Rob Nelson had no idea of what might happen when he volunteered to help his friend - renegade scientist Alexander Haig -with his bizarre experiment. But now he finds himself trying to sweet-talk his wife (who has just buried him) into believing that he is alive; convince a ruthless murderer that he is dead; and prove to himself that he is himself. - Amazon
