A Cold Heart, by Jonathan Kellerman

An Alex Delaware / Milo Sturgis novel. This was an audio book. Published in 2003.

This book begins with the murder of a blues guitarist named Baby Boy who has just come out of rehab and is on the road to making a comeback with his music. As Delaware and Sturgis become involved, as well as Det. Petra Connor and a new character named Det. Stahl, it becomes evident that this murder is related to others, and the mystery deepens.

I was a bit worried about Detective Eric Stahl, as he seemed doomed from the beginning of the story, similar to the joke about the nameless character you've never seen before in any given Star Trek episode, but he turned out to be a bit more multi-dimensional.

It's a good mystery with decent denoument. Kellerman is a master of the form.

At this stage of the series, Delaware is not living with Robin, and has a new woman-friend named Allison, who is also a psychotherapist. Milo is still with Rick, Petra is single. Eric Stahl's story is revealed near the end of the book.
