This is the fourth book in the John Dunning's "Bookman" series, with Cliff Janeway, an ex-cop turned book dealer as the protagonist. Janeway's lawyer girlfriend Erin has been contacted by her ex-best friend Laura to help defend her against a murder rap. The victim is Laura's husband; Laura had "stolen" him from Erin years ago. Erin asks Janeway to check it out, and, predictably, mayhem ensues.
I really liked the first book in this series, Booked to Die; the second and third, while good, let me down a little. This one, however, I liked a lot. It's full of interesting characters and tense situations, held together by sharp writing.
