Which pseudonym was revealed as J.K. Rowling’s in 2013?

Robert Galbraith was the pseudonym revealed as J.K. Rowling’s in 2013.

The name appeared on The Cuckoo’s Calling, a crime novel published in April 2013. The book was presented as the work of a former military police investigator, but Rowling was later identified as its actual author. The revelation led to a sharp increase in sales and widespread media coverage.

Rowling had wanted the crime novel to stand on its own and to receive an independent assessment from readers and reviewers. Robert Galbraith therefore differs from her public Harry Potter identity, while remaining an author credit associated with the Cormoran Strike books. The pseudonym is sometimes mistaken for a separate writer because it was initially promoted as one.
