What is the name of J.K. Rowling’s detective series written under a pseudonym?

J.K. Rowling’s detective series written under a pseudonym is the Cormoran Strike series. She published the books under the name Robert Galbraith.

The series follows Cormoran Strike, a private investigator in London, and Robin Ellacott, who becomes his professional partner. The first novel, The Cuckoo’s Calling, appeared in 2013. Its crime-fiction style differs from the fantasy setting of Harry Potter, focusing on investigations, evidence, suspects, and the social worlds surrounding each case.

The pseudonym was publicly revealed in 2013, after the author’s identity was reported. Rowling continued using Robert Galbraith for the series, and later novels expanded both the cases and the relationship between Strike and Robin. Cormoran Strike should not be confused with the names of the individual novels, which include The Silkworm and Career of Evil.
