What was the title of J.K. Rowling’s first published crime novel featuring Cormoran Strike?

J.K. Rowling’s first published crime novel featuring Cormoran Strike was The Cuckoo’s Calling.

The novel was published in 2013 under the name Robert Galbraith. It introduces Cormoran Strike, a private detective and former military investigator, and Robin Ellacott, who becomes his temporary secretary and later an important professional partner.
