Detection Unlimited - Georgette Heyerová

Slumped on a seat under an oak tree is old Sampson Warrenby, with a bullet through his brain. He is discovered by his anxious niece, Mavis, who is just one of the tne people in the village in the running for chief suspect, having just cause to dislike Warrenby intensely. Only Chief Inspector Hemingway can uncover which of the ten has turned hatred into murder.
