A Divided Loyalty by Charles Todd--Inspector Ian Rutledge returns in this intriguing mystery, set in England in 1921. A young woman is found murdered at the bottom of one of the plinths that make up the Avebury stone circle. No one knows who she is so the hunt is on. Rutledge is a terrific character who gets more interesting with each book. Here he struggles with the politics of Scotland Yard; his supervisor would be happy if he failed to solve the crime.
