Kellerman Jonathan. Mystery 3/3

The title, "Mystery" refers to the name taken by a high end prostitute in Los Angeles, who manages to get murdered by persons unknown. "Persons" unknown, because she was killed by two shots - fired simultaneously - by two guns.
Alex Delaware and his lady friend, Robin, were among the last to see her alive and he's brought into the case by his friend, Lt Milo Sturgis. There's a secondary case - about a dying madam - that Delaware is also involved in. As usual in these plots, the two storylines do meet briefly. There's also the requisite rich and creepy and malevolent Beverly Hills family involved in all this.One of the past complaints about Jonathan Kellerman's series is the highlighting of Milo Sturgis instead of Alex Delaware. This book brings the two together in a more even way. It's a good story, well-written, and one his long-time fans will enjoy.
