Writer's block is nothing compared to the sinister assignment London-based novelist Matt Wells has just received. A chain of seemingly innocent e-mails from a devoted fan turns deadly when Matt discovers the correspondent is a cold-blooded killer with an agenda for murder—and his family and friends are among the scheduled victims.

Under close surveillance, Matt is plunged into a plot more twisted than any he has used in his novels. This is the real thing, and with each killing, the man known as the White Devil tightens his grip by incriminating Matt at the murder scenes. Cast not only as the ghostwriter of his persecutor's terrifying story, but as the victim, Matt needs to risk everything to protect his loved ones. But with the police closing in and his friends being picked off, he is running out of time. The White Devil is out there— and he's watching.
