Which pseudonym appears on J.K. Rowling’s crime-fiction series featuring Cormoran Strike?

The pseudonym Robert Galbraith appears on J.K. Rowling’s crime-fiction series featuring Cormoran Strike.

The series began with The Cuckoo’s Calling, published in 2013. Its central character, Cormoran Strike, is a former military investigator who works as a private detective in London. Robin Ellacott joins his agency, and their evolving partnership becomes one of the series’ continuing threads.

Rowling selected a separate author identity to let the books stand on their own merits and to write in a different genre. The pseudonym was presented as belonging to a former Royal Military Police investigator, a detail that supported the books’ crime-fiction framing.

A leak exposed Rowling as the author soon after publication, and later editions identified the connection. The series has retained the Robert Galbraith credit, so readers may see both names associated with the same novels.
