HBJ, 1976. Ex-lib reading copy.
It seemed simple at first; a retired manufacturer is found dead, shot with his own pistol, and the last person to see him was his son-in-law, a respected doctor. When Inspector Maigret examines the scene, he finds that the situation is a complex one involving the man's whole family. With no real evidence, Maigret relies on his famous intuition to find the surprising truth.
