This is a departure from Harvey's normal detective Resnick series, introducing a couple of new characters, both police officers. One is a black woman based in London, the other an almost retired man living in Cornwall. Harvey tries to link their stories together, but is unsuccessful. I got lost trying to figure out who some of the characters were. By the end of the book I was still none the wiser in some cases. I assume the stories came to a satisfactory conclusion, but I'll have to read it again to make sure.
