What was the title of J.K. Rowling’s first published book under the Robert Galbraith name?

J.K. Rowling’s first published book under the Robert Galbraith name was The Cuckoo’s Calling.

The crime novel was published in April 2013 and introduced private detective Cormoran Strike and his temporary secretary, Robin Ellacott. Its plot follows Strike’s investigation into the death of supermodel Lula Landry in London.

The book was initially presented as the work of Robert Galbraith, described as a former military policeman. Rowling’s authorship was revealed later in 2013 after a linguistic analysis and media reporting connected her with the novel. She then confirmed that she had written it.

The later Strike novels continued under the Galbraith name. Readers sometimes confuse this title with The Silkworm, which is the second novel in the series, or with Rowling’s separate adult novel The Casual Vacancy.
