Under what pseudonym did J.K. Rowling write the Cormoran Strike novels?

J.K. Rowling wrote the Cormoran Strike novels under the pseudonym Robert Galbraith.

The first book in the series, The Cuckoo’s Calling, was published in 2013 and introduced private detective Cormoran Strike and his assistant Robin Ellacott. The books are crime novels rather than fantasy, with investigations set mainly in contemporary Britain.

The pseudonym was intended to let Rowling publish without the immediate expectations attached to her name. The identity was publicly revealed in 2013 after an analysis connected the writing to Rowling. She continued the series under the Galbraith name after the revelation.

Robert Galbraith should not be confused with Stephen King’s pseudonym Richard Bachman or Daniel Handler’s literary persona Lemony Snicket. Those are separate author identities belonging to different writers.
