With her gift for sniffing out the malevolent side of human nature, Miss Marple is led on her first case to a crime scene at the local vicarage. Colonel Protheroe, the magistrate whom everyone in town hates, has been shot through the head. No one heard the shot. There are no leads. Yet, everyone surrounding the vicarage seems to have a reason to want the Colonel dead. It is a race against the clock as Miss Marple sets out on the twisted trail of the mysterious killer without so much as a bit of help from the local police.
