Which detective character did J.K. Rowling create under the pseudonym Robert Galbraith?

J.K. Rowling created the detective character Cormoran Strike under the pseudonym Robert Galbraith.

Cormoran Strike first appears in The Cuckoo’s Calling, published in 2013. He is a private investigator and former military police investigator working in London. His business partner, Robin Ellacott, becomes an important recurring character as the series develops.

Rowling initially published the book under the name Robert Galbraith. The pseudonym was publicly identified as Rowling in 2013, after the book’s authorship was revealed. Later Strike novels continued to be credited to Robert Galbraith, preserving the detective series’ separate author identity.

Strike is not a wizarding character and does not belong to the Harry Potter universe. The series is contemporary crime fiction, and its titles include The Silkworm, Career of Evil, and Lethal White.
