Which J.K. Rowling novel introduced the character Cormoran Strike?

The Cuckoo’s Calling introduced J.K. Rowling’s detective character Cormoran Strike.

The novel was published in 2013 under the pseudonym Robert Galbraith. Strike investigates the death of model Lula Landry in London, assisted by Robin Ellacott, who becomes an important recurring character in the series.

Rowling’s authorship was initially kept secret, but it was publicly identified later in 2013. The revelation changed the book’s commercial fortunes and confirmed that the new crime series came from the author of Harry Potter.

The later novels The Silkworm, Career of Evil, Lethal White, Troubled Blood, The Ink Black Heart, and The Running Grave continue the Strike series. The books are sometimes listed under Rowling’s name and sometimes under the Galbraith pseudonym.
