The Cormac Reilly series begins with The Ruin (2018), where Reilly returns to Galway and is drawn back into a case he first encountered as a young officer. The Scholar (2019) keeps him in the university city for a new investigation. The series grows from there with The Good Turn (2020) and The Unquiet Grave (2025), plus shorter entries like The Sisters (2019) and The Roommate (2020).
McTiernan writes Galway as a character in its own right, with the rain, the university, and the small-city tensions shaping every story. Reilly is a patient, observant detective, and the books reward readers who follow the recurring characters across multiple entries.
