Stone Rain (Zack Walker, Bk. 4)

Metropolitan newspaper writer Zack Walker has a knack for stumbling onto deadly stories. But it's one that his good friend Trixie Snelling doesn't want told that's about to unleash a storm of trouble. As a professional dominatrix in the suburbs, Trixie has her share of secrets, but Zack has no idea what she's really hiding when a local newspaperman threatens to do an expose on her...not until Zack finds a dead body strapped to the bondage cross in her basement dungeon.
Now Zack is implicated in a murder, Trixie is missing, and everything he thought he knew about his friend, his town, even his own marriage, reveals a darker side. Zack's twisted trail to the truth will lead to a long-unsolved triple homicide, bikers, drug wars, and a stone-cold killer hell-bent on revenge. It's a story that's already cost him his job and possibly his wife, and, if Zack's not very lucky, it will cost him his life.
