The Cold Cold Ground
Northern Ireland, spring 1981. Hunger strikes, riots, power cuts, a homophobic serial killer with a penchant for opera, and a young woman’s suicide that may yet turn out to be murder: on the surface, the events are unconnected, but then things—and people—aren’t always what they seem. Detective Sergeant Duffy is the man tasked with trying to get to the bottom of it all. It’s no easy job—especially when it turns out that one of the victims was involved in the IRA but was last seen discussing business with someone from the loyalist Ulster Volunteer Force. Add to this the fact that, as a Catholic policeman, it doesn’t matter which side he’s on, because nobody trusts him, and Sergeant Duffy really is in a no-win situation.

Adrian McKinty
Adrian McKinty writes crime fiction where the ordinary collides with the unforgiving, and the tension never lets go. Born in Belfast in 1968, he grew up amid the Troubles, a backdrop of political unrest and divided loyalties that quietly shaped his sense of morality and justice. Those early experiences of a society on edge became the heartbeat of his fiction, giving his novels a texture that’s both authentic and unsettling.
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.
Sean Duffy
Amid the foggy streets and tense neighborhoods of 1980s Belfast, the Sean Duffy series immerses readers in a city brimming with secrets, suspicion, and moral complexity. At its heart is a detective navigating not just violent crime, but the invisible pressures of a society divided by politics, religion, and loyalty. Each case is more than a puzzle, it is a collision of personal ethics, institutional corruption, and the everyday realities of life under constant scrutiny.
Sean Duffy consists of eight primary books, and includes one additional book that complement the series but is not considered mandatory reads and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
