Dervla McTiernan grew up in Ireland and moved to Australia, where she began writing crime fiction. Her debut, The Ruin (2018), introduced Detective Cormac Reilly and the Galway, Ireland setting that would anchor her main series. The Cormac Reilly books follow Reilly through cold cases and new crimes in the west of Ireland, with each book building on the relationships and tensions from earlier entries.
Outside the series, McTiernan has written standalone thrillers that show a different side of her work. The Murder Rule (2022) is a legal thriller set in the United States. The Fireground (2023) and What Happened to Nina? (2024) are both standalones with separate casts and settings, letting McTiernan explore different kinds of crime stories.
