Detective Constable Tom Kessler has spent his career chasing violent men, drug traffickers, and predators who thrive in the shadows. Pete Johnson has survived in those same shadows-sharp-witted, disciplined, and far more loyal than any criminal has a right to be. When a surveillance job goes catastrophically wrong and a ruthless crime boss threatens Tom's family, the straight-edged detective turns to the last man he should ever trust.

What begins as a desperate warning becomes an unlikely alliance. Pete becomes Tom's covert informant, guiding him through a world of encrypted phones, Irish suppliers, violent enforcers, and the constant threat of discovery. Their partnership deepens as they close in on a dangerous kingpin-until a powerful MP assaults Pete's wife and walks away untouched, forcing Tom and Pete into a darker, more personal war.

From the estates of Surrey to the backstreets of Holyhead and Dublin, and into the orbit of foreign intelligence services, the two men navigate betrayal, surveillance, political corruption, and escalating violence. Every move draws them closer to the truth, closer to each other, and closer to disaster.

Gritty, authentic, and driven by moral complexity, this two-book bundle blends procedural realism with high-stakes intrigue. Perfect for readers of Stephen Leather, Mick Herron, Henry Porter, and anyone who craves British crime thrillers where loyalty is dangerous, justice is costly, and one mistake can get you killed.
