About the Cormac Reilly series
Dervla McTiernan's Cormac Reilly novels are atmospheric, intelligent Irish crime fiction set in and around Galway. Detective Cormac Reilly, transferred from Dublin under a cloud, finds himself reopening a decades-old case and navigating a police force riddled with secrets and quiet corruption.
McTiernan combines satisfying procedural mystery with sharp social observation about modern Ireland — institutional failure, class, the long shadow of the past. The cases are layered and the characters richly drawn.
Reilly's arc and the recurring cast develop across the books, so reading in order from "The Ruin" is recommended.
