Hailing from Navan in the royal county of Meath, Domhnall is a graduate of the Bachelor in Acting Studies Programme, Trinity College Dublin, later completing a Master's in Screenwriting at Dún Laoghaire IADT. He now works as an actor and a journalist, dividing his time between Galway, where he films TG4’s flagship series, Ros na Rún, and Venice, where he and his Italian lover continuously promise their well-worn livers that they will refrain from quaffing so much Prosecco. (Unfortunately, it seems some vows, just like nearby Rome, were not built in a day.)

Wine-drinking aside, for more than four years, Domhnall has also enjoyed the responsibility of being Assistant Editor at Irish Tatler Man, a title that won Consumer Magazine of the Year '15/16. Thanks to this role, he interviewed a host of high-profile names, such as Tommy Hilfiger, Chris Pine, Kevin Spacey, David Gandy and Jacques Villeneuve. As a screenwriter, Domhnall co-wrote the short film, A Clown’s Requiem, which was the recipient of funding from the Irish Film Board and premièred at the Galway Film Fleadh. With Co-operation Ireland, a peace-building charity, Domhnall works as an arts mentor. As a result of this work, he met Queen Elizabeth and President Higgins in Belfast in 2012.

When writing his debut novel, Sister Agatha: The World’s Oldest Serial Killer — a comedy thriller that follows a 118-year-old nun who will go to any length in her quest to become the globe’s most senior citizen — Domhnall, the actor, called upon his natural curiosity of the human spirit to create larger-than-life characters, while Domhnall, the journalist, drew upon his extensive experience as a travel writer to provide inspiration for the story’s numerous settings. And as for his fascination with religious orders and the Catholic Church? Being an enthusiastic altar boy for most of his childhood might be the best explanation for that.

Sister Agatha: The World's Oldest Serial Killer

Sister Agatha is a colossal 118 years of age and has one ambition in life: to be the oldest person in the world. At last count, she’s the fifth. During a routine check-up, however, her doctor says she has just one week to live. Passport in hand, she plans to travel across three continents and meet the four people standing in her way. And then, one by one, she intends on killing them.
