Book excerpt: In a seedy hotel near Ground Zero, a woman lies face down in a pool of acid, features melted of her face, teeth missing, fingerprints gone. The room has been sprayed down with DNA-eradicating antiseptic spray. Pilgrim, the code name for a legendary, world-class segret agent, quickly realizes that all of the murderer's techniques were pulled directly from his own book, a cult classic of forensic science written under a pen name.
