What is the title of J.K. Rowling’s first novel written as Robert Galbraith?

J.K. Rowling’s first novel written as Robert Galbraith is The Cuckoo’s Calling.

The Cuckoo’s Calling is a crime novel featuring private detective Cormoran Strike and his temporary secretary, Robin Ellacott. It was first published in April 2013 under the name Robert Galbraith, presented at the time as the debut of a former military police officer.

The story begins when model Lula Landry dies after falling from a London apartment balcony. Police treat the death as suicide, but Lula’s brother hires Strike to investigate whether she was killed. The novel develops through interviews, evidence, and Strike’s deductions.

Rowling’s authorship became public in July 2013 after an analysis identified similarities between the book and her known writing. The later Strike novels continued to use the Robert Galbraith name. The Cuckoo’s Calling is the title of the first book, while the series is generally called the Cormoran Strike series.
