Publisher's Synopsis
In New York City a murderer is on the loose: the Doomsday Killer has claimed six victims in two weeks. The police are mystified: the victims have nothing in common, all that connects them is that each had received a postcard, before they died, announcing their date of death. In desperation, the FBI assigns the case to maverick agent Will Piper, a man on a dissolute spiral to retirement. Battling his own demons, Will uncovers a shocking secret that has been closely guarded for centuries. This secret once lay buried in an underground library beneath a monastery and has now been unearthed. But the secret of the library is defended by people who would stop Will finding out the truth - at any cost.
