'When someone takes advantage of a duck hunt to murder publisher Athol Sefton at a remote hunting inn, it soon turns out that almost everyone, guests and staff alike, had good reason to shoot him. Sefton’s nephew Charles believes he can solve the crime by applying the traditional “rules of the game” he’s absorbed over years as a reviewer of detective fiction. Much to his annoyance, however, the killer doesn’t seem to be playing by those rules, and Charles finds that he is the one under suspicion.'
