Freaks — Tess Gerritsen

In the murky shadows of Boston's Chinatown lies a severed hand. On the tenement rooftop above is the corpse belonging to that hand, a red-haired woman dressed in black, her head nearly decapitated. Two strands of silver hair -- not human -- cling to her body. They are homicide cop Jane Rizzoli's only clues, but they're enough for her and medical examiner Maura Isles to make the startling discovery: that this violent death had a chilling prequel. Nineteen years earlier, a horrifying murder-suicide in a Chinatown restaurant left five people dead. One woman connected to that massacre is still alive -- a mysterious martial arts master who is now the target of someone, or something, deeply and relentlessly evil. Cracking a crime with bone-chilling echoes of an ancient Chinese legend, Rizzoli and Isles must outwit an unseen enemy with centuries of cunning -- and a swift, avenging blade.
