Gilbert Worth, adulterous husband and acerbic novelist, is found dead in his study with a bullet in his temple and the smoking gun clenched in his hand. Much to Gilbert's surprise he seems to have survived the murder -- or rather his ghost has survived to look upon his own corpse. While the members of his family believe he has committed suicide Gilbert knows better. Someone killed him. Someone who tried unsuccessfully twice before - once with a carefully placed glass marble on the staircase, the second when his nighttime warmed milk was tainted with something bitter and palatable. He fed it to the cat and it was dead in the morning. Gilbert's spirit seems doomed to walk the Earth until he is satisfied with just who in his household hated him so much to send him off to an early reward. Though it's not so rewarding to Gilbert even if he can pass through walls and enter locked rooms without being seen.
