Body Double by Tess Gerritsen

I'm a firm believer that the first book in a series is always going to be the best and most of the novels afterwards are a waste of time on the writers part. However, Body Double definitely reaches the same level as the Surgeon. Although this book was more focused on connecting cold cases than present murders it was constantly intriguing. When it appears as though Maura has been murdered, it is discovered that she in fact had an identical twin who was given to a different family during their adoptions. In the mix of finding the truth about Isles's birth family, Jane is carrying her first child and trying to solve a serial killing mystery involving the "harvesting" of babies and murders of their mothers. The two issues collide when Maura finds out the true identity of her schizophrenic mother who is serving life in prison for murder. The cycling pattern of murdered women proves to be a result of a twisted family business, which is finally ended by the most recently abducted housewife, Mattie.
