Nightingale, Book 1

Jack Nightingale Series Website
The last words spoken in Jack's final case as a police negotiator have been haunting him ever since leaving the job. He'd been a cop long enough to see people at their worst, to doubt the existence of God, heaven, hell, or souls. Now a struggling private detective, the chilling words return with a vengeance when Jack inherits a mansion with a priceless library—and a terrifying warning from a man who claims to be his father.
Nightingale quickly learns his soul was sold at birth and a devil will come to claim it on his thirty-third birthday, which is just three short weeks away. It’s a hard pill to swallow. He doesn't believe in Hell and probably doesn't believe in Heaven either. But when people close to him start to die horribly, he is led to the inescapable conclusion that real evil may be at work. And if he doesn't find a way out, he'll be damned for eternity.
