About the Sean Duffy series
Sean Duffy is a Catholic detective in the overwhelmingly Protestant Royal Ulster Constabulary, working murder cases in Carrickfergus, Northern Ireland, during the worst years of the Troubles -- a position that makes him a target from both sides before he's even opened a case file. Adrian McKinty, who grew up in Carrickfergus himself, uses Duffy's beat to walk readers through the paranoia and dark comedy of daily life under bomb checks, checkpoints, and sectarian murder: he mirrors his car for booby traps every morning as a matter of routine, drinks and reads Camus to cope, and solves genuinely twisty locked-room and impossible-crime mysteries while the political violence around him escalates from book to book.
The series opens with The Cold Cold Ground in 1981, against the backdrop of the IRA hunger strikes, and advances roughly a year or two at a time through the decade, with real historical events -- the Falklands War, the Brighton hotel bombing, the 1984-85 miners' strike, the fall of the Berlin Wall -- woven into the plots rather than merely referenced. McKinty pauses the series after six novels covering 1981-1984, then returns years later to continue Duffy's story into the later 1980s and early 1990s. Critically garlanded from the start, the series has won the Edgar Award, the Ned Kelly Award (three times), the Anthony Award, the Barry Award, and the Theakston Old Peculier Crime Novel of the Year Award, and is frequently cited as one of the finest sustained achievements in modern crime fiction.
