Which pseudonym did J.K. Rowling use when publishing The Cuckoo’s Calling in 2013?

J.K. Rowling used the pseudonym Robert Galbraith when publishing The Cuckoo’s Calling in 2013.

The novel is a crime mystery featuring Cormoran Strike, a private investigator and former military police officer. It was presented as the debut work of Robert Galbraith, whose supposed background was described as connected to the security services.

The book received positive reviews before Rowling’s identity became public. A linguistic analysis by Patrick Juola helped identify Rowling as the author, and the disclosure was reported in July 2013. Rowling later confirmed that she had written the novel.

The revelation did not end the pseudonym. Subsequent Cormoran Strike novels, including The Silkworm and Career of Evil, continued to be published under the Robert Galbraith name. This identity is separate from Rowling’s own-name adult fiction and children’s books.
