From Potter's Field Cornwell, Patricia

Christmas Eve in New York, and Kay Scarpetta is chasing a killer through the frozen tunnels beneath the city. A woman's body, stripped and mutilated, left in the snow outside a church — the signature marks of Temple Brooks Gault, the psychopath who's haunted Scarpetta across state lines and case files. This time it's personal. Gault is taunting her, and the hunt leads from the morgue to the underground homeless camps where the city's forgotten live in shadows. Cornwell writes with surgical precision — literally. The forensics are brutal, the pacing relentless, the psychological stakes suffocating. This is the sixth in the Scarpetta series, and it's Patricia Cornwell at her darkest. For fans of Kathy Reichs, Jeffery Deaver, or anyone who likes their crime fiction cold, methodical, and impossible to put down after midnight.
