What is the title of J.K. Rowling’s first published adult novel under the pseudonym Robert Galbraith?

The Cuckoo’s Calling is J.K. Rowling’s first published adult novel under the pseudonym Robert Galbraith. The crime novel was published in 2013 and introduces private investigator Cormoran Strike and his temporary secretary, Robin Ellacott.

The story begins with the death of model Lula Landry, which is initially treated as a suicide. Strike investigates the case and the novel develops through interviews, conflicting testimony, and the details of London social life. Its detective structure differs sharply from the fantasy setting of Harry Potter.

The novel was initially attributed to Robert Galbraith, but Rowling’s authorship became public soon after publication. The revelation led to a large increase in attention and sales. The later books The Silkworm, Career of Evil, Lethal White, Troubled Blood, and The Running Grave continue the Cormoran Strike series, so they are not the first Galbraith novel.
