Rottweiler

The first victim was discovered with a bite on her neck. The police traced the DNA to the girl's boyfriend, but the tabloids had already dubbed the murderer "The Rottweiler," and the name stuck. The latest body was found near Inez Ferry's shop in Marylebone. Someone spotted a figure fleeing into the shadows, but couldn't say even if it was man or woman. The only other clues are the murderer's penchant for strangling his prey, and for then removing a small token -- a necklace, a lighter. Rendell is in top form here as she deftly propels the narrative, alternating between the inner life of a compulsive killer and the daily affairs of those who live nearby, unknowing yet somehow aware of his presence.
