"Sometimes, kid, we have to dance with the devil. And he's calling the tune."

Tommy Kelly may be banged up, but he's still pulling the strings. Calling Eddie Savage back into the world of intelligence to track down his daughter, Sophie, the king of crime is venturing into an uneasy relationship with the law. Eddie, meanwhile, has his own reasons for accepting the job. But it's one that requires him to infiltrate the dark heart of the real IRA, a world of kneecappings, bare-knuckle fighting and horse trading – and to go beyond that to a murkier, harder place altogether; one that brings flooding back the circumstances around his brother's death. Eddie wonders if this time he really has done a deal with the devil.
