Alex Cross Run (#17) by James Patterson

Alex Cross is on the hunt for his life...in Washington, D.C., top plastic surgeon Elijah Creem is renowned for his operating skills-and his wild parties of drugs, champagne and illicit sex. When Detective Alex Cross busts one of Creem’s soirees, the doctor takes the most drastic step to avoid prison. Before Alex can finish this case, a beautiful woman is murdered with a lock of her hair viciously ripped off. Then a second woman is found, hanging from a window with a brutal scar slashed across her stomach. After a third mutilated body is discovered, rumors of three serial killers on the loose send the city into an all-out frenzy. But under intense pressure to solve all these grim cases, the detective doesn't notice that someone very obsessed and twisted is stalking him- and won’t stop until Alex is dead.
