Jack Devlin and The One Series
The Jack Devlin “ONE” series is a hard‑edged, high‑velocity set of crime thrillers about a private security specialist who operates outside the boundaries of polite society—and often outside the law. Jack Devlin is the man people call when they’ve run out of options, when the system has failed them, or when the threat they face is too violent, too connected, or too corrupt for anyone else to touch.
Devlin is not a detective. He’s not a vigilante. He’s a fearsome force of will – shaped by reality, sharpened by violence, and driven by a personal code that demands action when others can’t or won’t.
RESCUE AND SURVIVAL
ONE WAY OUT
She is Jack Devlin’s first love, and her life is about to be destroyed. She’s trapped between a ruthless drug gang of Jamaican “Yardies” and Eastern Bloc criminals more violent than anything the London Met have ever faced. The only way out Devlin can find is a one-time only option that will change Devlin forever – if he
survives.
