What is the name of J.K. Rowling’s first published Cormoran Strike novel?

The Cuckoo’s Calling is the first published Cormoran Strike novel by J.K. Rowling.

The book was published in 2013 under the pseudonym Robert Galbraith. It introduces Cormoran Strike, a private detective and former military investigator, who is hired to examine the death of model Lula Landry. Robin Ellacott joins the investigation as Strike’s temporary secretary and becomes an important continuing character.

The novel was initially received as the work of a new crime writer. Rowling’s authorship was later revealed, creating major public interest and sending the book back up bestseller lists. She continued the series with The Silkworm, Career of Evil, Lethal White, Troubled Blood, and The Ink Black Heart.

The title is sometimes confused with later Strike books, especially The Silkworm. The Cuckoo’s Calling is specifically the series opener and the novel that establishes Strike and Robin’s professional partnership.
