In her twenty-second book featuring Inspector Wexford, the diligent detective debuted in 1964Â’s From Doon with Death, Ruth Rendell delivers a brilliant and fascinating tale that revolves around a man Wexford suspects to be a serial killer.Wexford had almost made up his mind that he would never again set eyes on Eric Targo's short, muscular figure. And yet there he was, back in Kingsmarkham, still with that cocky, strutting walk. Years earlier, when Wexford was a young police officer, a woman called Elsie Carroll had been found strangled in her bedroom. Although many still had their suspicions that her husband was guilty, no one was convicted. Shortly afterwards, another woman was strangled, and every personal and professional instinct told Wexford that the killer was still at large.
