Under which pen name was J.K. Rowling’s crime novel The Cuckoo’s Calling first published?

J.K. Rowling’s crime novel The Cuckoo’s Calling was first published under the pen name Robert Galbraith.

The novel appeared in 2013 and introduced private investigator Cormoran Strike, who investigates the death of a famous model in London. Rowling chose the pseudonym to publish in a different genre without the immediate expectations attached to her Harry Potter reputation.

The authorship was revealed later in 2013, after an analysis identified Rowling as the writer. Robert Galbraith remains the credited author name for the Cormoran Strike series. The name is not a character in the novels: Cormoran Strike is the detective, while Robert Galbraith is the authorial pseudonym.
