Flipping Out by Marshall Karp
Someone is making a real killing on the housing market - Bestselling mystery author Nora Bannister has found herself a very lucrative sideline. Along with a group of female friends, she buys a run-down house in Los Angeles, and while her business partners turn it into a show home, Nora makes it the scene of a grisly murder in her latest bestseller. It seems people are only too happy to live in a house where someone has died a violent death - in fiction, at least. But, much to the horror of Nora and her pals, a series of real murders start taking place - Detectives Mike Lomax and Terry Biggs have to track down the killer before he murders his next logical target - Marilyn, Terry's wife.
