Sleeping Doll by Jeffery Deaver

Featuring Katheryn Dance

Kathryn Dance, an investigator with the California Bureau of Investigation, is the lead cop handling the escape of psychopathic killer Daniel Pell. Pell dubbed "Son of Manson" by the press for his "family" of young runaways and his most horrendous crime, the murders of computer engineer William Croyton, Croyton's wife and two of their three children. The only child left alive, nine-year-old Theresa, is known as the Sleeping Doll. Pell, charismatic and diabolically intelligent, continually eludes capture, but Dance, a specialist in interrogation and kinesics (or body language), is never more than a few suspenseful minutes behind.

As with all Deaver's books there is a big twist that kept on coming. It kept me guessing and I enjoyed learning more about Dance's character and her specialty of kinesics. This series is much less violent than his other series and I enjoy the mental aspects of it as well.
