The first girl had a bite mark on her neck. When the tabloids got hold of the story, they immediately called the killer 'The Rottweiler', and the name stuck. The latest body was discovered very near Inez Ferry's antique shop in Marylebone. Someone spotted a shadowy figure running away past the station, but couldn't say for sure if it was a man or a woman. There were only two other clues. The murderer seemed to have a preference for strangling his victims and then removing something personal - like a cigarette lighter or a necklace...Since her actor husband died, too early into their marriage, Inez supplemented her modest income by taking in tenants above the shop. The unpredictably obsessive activities of 'The Rottweiler' would exert a profound influence on this heterogeneous little community, especially when the suspicion began to emerge that one of them might be a homicidal maniac.
