Paging Dr. Scarpetta: Fans of Patricia Cornwell's crime series starring medical examiner Kay Scarpetta have much to cheer about. The Bone Bed, 20th in the series, makes its debut at No. 1 on the list. It's the 12th Scarpetta novel to land on the list at No. 1. Cornwell, who once worked for Virginia's chief medical examiner, published her first Scarpetta novel, Postmortem, in 1990. Cornwell's attendance at thousands of autopsies and her expertise in law enforcement are credited with giving her books their authenticity. -Carol Memmott
