The eponymous character in the Quirke series is a pathologist based in 1950s Dublin. The first three books, Christine Falls (2006), The Silver Swan (2007), and Elegy for April (2011) were made into a drama series, Quirke which — after being shown in Ireland — aired on British television. Subsequent books in this series were: A Death in Summer (2011), Vengeance (2012), Holy Orders (2013), Even the Dead (2016), April in Spain (2021), The Lock-Up (2023) and The Drowned (2024). The last three of those appeared under Banville's own name. A related book — this one also published under Banville's name — is Snow (2020). This featured a character named Detective Inspector St John Strafford, who appeared in subsequent books April in Spain and The Lock-Up.

Also published under the name Benjamin Black are crime books The Lemur (2008), The Black-Eyed Blonde (a Philip Marlowe novel, 2014), and Prague Nights (2017).

The Secret Guests (2020) is a work of alternative history crime, based on a scenario in which the young British princesses, Elizabeth and Margaret, are evacuated to County Tipperary in 1940 to escape the London Blitz and a possible German invasion of Britain. Again featuring St John Strafford, this book was published under the name B. W. Black.

Style

The critics regard Banville as a master stylist of English, with his writing considered as perfectly crafted and dazzling. Described as "the heir to Proust, via Nabokov", he is known for his dark humour and sharp wit.

Michael Ross stated that Banville is "perhaps the only living writer capable of advancing fiction beyond the point reached by Beckett". Gerry Dukes, reviewing The Sea in the Irish Independent, hailed Banville as a "lord of language".

Literary influences

Banville said in an interview with The Paris Review that he liked Vladimir Nabokov's style; however, he went on, "But I always thought there was something odd about it that I couldn't quite put my finger on. Then I read an interview in which he admitted he was tone deaf."

Banville has said that, as a boy, he imitated James Joyce: "After I'd read The Dubliners, and was struck at the way Joyce wrote about real life, I immediately started writing bad imitations of The Dubliners." Responding to a suggestion that Fyodor Dostoevsky and Albert Camus were worthy comparisons, Banville said: "Dostoyevsky is such a bad writer it is hard to take him seriously... Ditto Camus". On women in his own writing, Banville told Niamh Horan of the Sunday Independent in 2012: "I don't make a distinction between men and women. To me they are just people". Horan herself noted Banville's "special flair for writing about women and delving into the female psyche".

Banville contributed the introduction to the fifty-year retrospective of Edna O'Brien's work, The Love Object: Selected Stories, praising her as "one of the most sophisticated writers now at work" and noting how it was "hard to think of any contemporary writer who could match [O'Brien's] combination of immediacy and sympathetic recall". He noted how "striking" is the figuring of O'Brien's characters and acknowledged that all her characters "are in some way damaged by the world, and specifically by the world of men". Banville concluded by describing O'Brien as "simply one of the finest writers of our time".

Banville dedicated himself to the task of writing the screenplay for an adaptation of Elizabeth Bowen's novel The Last September. Banville later wrote the introduction for her Collected Stories.

Close to the literary editor Caroline Walsh, Banville spoke of his devastation upon learning of her death. He dedicated Ancient Light to her. Likewise, Banville was close to Eileen Battersby, at whose funeral he was moved to tears whilst reciting a poem in her memory.

Crime and punishment

Speaking to Niamh Horan in 2012, Banville related his thoughts on hurt and responsibility: "To hurt other people is the worst thing you can do. To be hurt oneself is bad enough, but hurting other people is unforgivable... Unforgivable. Literally unforgivable. I think that one has to take responsibility for one's life and one has to take responsibility for one's bad deeds as well as one's good deeds. One has to, as I say, be responsible... Failure in art, or failure in making a living, or a success—none of them compares, everything pales beside hurting other people, because, you know, we are here for such a short time and basic life itself is so hard one has a duty to try to be decent to other people".

On 21 August 2017, the RTÉ Radio 1 weekday afternoon show Liveline was discussing a report on Trinity College Dublin's use of 100,000 animals to conduct scientific research over the previous four years when a listener pointed out that Banville had previously raised the matter but been ignored. Banville personally telephoned Liveline to call the practice "absolutely disgraceful" and told the tale of how he had come upon some women protesting:
