I Am Pilgrim

Pilgrim is the codename for a man who doesn't exist. He once headed up a secret espionage unit for U.S. intelligence, and before he disappeared into anonymity, he wrote the definitive book on forensic criminal investigation. But that book will come back to haunt him. It will help NYPD detective Ben Bradley track him down, and it will force him into a terrifying race to save America from oblivion.
