Under what pseudonym did J.K. Rowling publish crime novels?

J.K. Rowling published her crime novels under the pseudonym Robert Galbraith.

The name first appeared on The Cuckoo’s Calling, a detective novel published in 2013. Its central investigator is Cormoran Strike, a private detective, and the series is co-written in the fictional author’s identity by Rowling. The pseudonym allowed her to publish in a different genre without the immediate expectations attached to her Harry Potter fame.

The book’s authorship was revealed after its publication, following analysis by linguists and later confirmation. Rowling then continued using the Robert Galbraith name for subsequent Cormoran Strike novels. The books are adult crime fiction rather than fantasy for children.

Robert Galbraith is not a separate person who independently created the series. The pseudonym is also distinct from Rowling’s name on The Casual Vacancy, her first adult novel, which was published under J.K. Rowling in 2012. The Galbraith books focus on investigations, London settings, and the partnership between Strike and Robin Ellacott.
