Which J.K. Rowling novel introduces detective Cormoran Strike?

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

Published in 2013 under the name Robert Galbraith, the novel follows Strike as he investigates the death of model Lula Landry in London. Robin Ellacott joins his struggling detective agency as a temporary secretary and becomes central to the series.

The book is the first of the Cormoran Strike novels. Later entries include The Silkworm, Career of Evil, Lethal White, Troubled Blood, The Ink Black Heart, and The Running Grave. Rowling’s use of a pseudonym allowed the crime series to develop independently before her authorship became public.
