And Minty does see ghosts

The Rottweiler

A series of apparently motiveless murders disrupts the lives of some very different people in Rendell’s darkly atmospheric London.

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.

To make ends meet, widowed Inez Ferry takes in tenants above her antique store. The unpredictable and obsessive acts of the serial murderer begin profoundly to disturb the lives of the heterogeneous little community of lodgers, especially when suspicion grows that one of them might be “The Rottweiler.”

17 August 2003. I did like this new Rendell very much. She has created characters who really live and the plot is great.
