Novels for adults
Doyle's first three novels, The Commitments (1987), The Snapper (1990) and The Van (1991) comprise The Barrytown Trilogy, a trilogy centred on the Rabbitte family. All three novels were made into successful films.
The Commitments is about a group of Dublin teenagers, led by Jimmy Rabbitte Jr., who form a soul band in the tradition of Wilson Pickett. The novel was made into a film in 1991. The Snapper, made into a film in 1993, focuses on Jimmy's sister, Sharon, who becomes pregnant. She is determined to have the child but refuses to reveal the father's identity to her family. In The Van, which was shortlisted for the 1991 Booker Prize and made into a film in 1996, Jimmy Sr. is laid off, as is his friend Bimbo; the two buy a used fish and chips van and they go into business for themselves.
In 1993, Doyle published Paddy Clarke Ha Ha Ha, which later won the 1993 Booker Prize, and which showed the world as described, understood and misunderstood by a ten-year-old Dubliner living in 1968.
Doyle's next novel dealt with darker themes. The Woman Who Walked into Doors, published in 1996, is the story of a battered wife, Paula Spencer, who was introduced in his 1994 television series Family, and is narrated by her. Despite her husband's increasingly violent behaviour, Paula defends him, using the classic excuse "I walked into a door" to explain her bruises. Ten years later, the protagonist returned in Paula Spencer, published in 2006.
Doyle's most recent trilogy of adult novels is The Last Roundup series, which follows the adventures of protagonist Henry Smart through several decades. A Star Called Henry (published 1999) is the first book in the series, and tells the story of Henry Smart, an IRA volunteer and 1916 Easter Rebellion fighter, from his birth in Dublin to his adulthood when he becomes a father. Oh, Play That Thing! (2004) continues Henry's story in 1924 America, beginning on the Lower East Side of Manhattan, where he catches the attention of local mobsters by hiring kids to carry his sandwich boards. He also goes to Chicago where he becomes a business partner with Louis Armstrong. The title is taken from a phrase that is shouted in one of Armstrong's songs, "Dippermouth Blues". In the final novel in the trilogy, The Dead Republic (published 2010), Henry collaborates on writing the script for a Hollywood film. He returns to Ireland and is offered work as the caretaker in a school when circumstances lead to him re-establishing his link with the IRA.
Doyle frequently posts short comic dialogues on his Facebook page which are implied to be between two older men in a pub, often relating to current events in Ireland (such as the 2015 marriage referendum) and further afield. These developed into the novella Two Pints (2012). Other recent works are The Guts (2013), which continues the story of the Rabbitte family from the Barrytown Trilogy, focusing on a 48-year-old Jimmy Rabbite and his diagnosis of bowel cancer and Two More Pints (2014).
