Seamus Ferreira is an Irish-Portuguese novelist whose atmospheric crime fiction maps the fault lines where cities keep their secrets. Born in 1983 to a schoolteacher from Galway and a shipwright from Aveiro, Seamus grew up between Connemara's wind-scoured harbors and Porto's steep, tile-bright streets. He studied comparative literature at Trinity College Dublin and later worked as a forensic auditor for an NGO investigating municipal corruption—an experience that sharpened his fascination with paper trails, silences, and the stories numbers tell.
Ferreira's work has been published in English and Portuguese. His breakout novel, Saltglass (2017), was followed by The Drowned Key (2020) and Nightjar's Claim (2022), both shortlisted for the Irish Book Awards Crime Novel of the Year and longlisted for the CWA Gold Dagger. He has contributed essays on Lusophone noir to the Journal of European Crime Writing and taught a seminar on urban secrecy at the Universidade do Porto. Seamus divides his time between Lisbon and Galway, researches in archives more than is probably healthy, and still writes first drafts with his grandfather's fountain pen.
