The Detective Up Late
From New York Times bestselling author Adrian McKinty comes the next thrilling mystery in the Edgar Award-winning Sean Duffy detective series
Slamming the door on the hellscape of 1980s Belfast, Detective Inspector Sean Duffy hopes that the 1990s are going to be better for him and the people of Northern Ireland. As a Catholic cop in the mainly Protestant RUC he still has a target on his back, and with a steady girlfriend and a child the stakes couldn't be higher.
After handling a mercurial triple agent and surviving the riots and bombings and assassination attempts, all Duffy wants to do now is live. But in his final days in charge of Carrickfergus CID, a missing persons report captures his attention. A fifteen-year-old traveler girl has disappeared and no one seems to give a damn about it. Duffy begins to dig and uncovers a disturbing underground of men who seem to know her very well. The deeper he digs the more sinister it all gets. Is finding out the truth worth it if DI Duffy is going to get himself and his colleagues killed? Can he survive one last case before getting himself and his family out over the water?

He first gained attention with the Sean Duffy series, beginning with The Cold Cold Ground, which follows a Catholic detective navigating the perilous landscape of 1980s Northern Ireland. McKinty’s work is defined by its moral complexity, unflinching realism, and darkly intelligent humor. He doesn’t just tell crime stories; he immerses readers in the pressures of a world where every choice carries weight and consequences are inevitable.
