What was the name of J.K. Rowling’s debut detective novel as Robert Galbraith?

The Cuckoo’s Calling was J.K. Rowling’s debut detective novel published under the name Robert Galbraith. It appeared in 2013 and introduces private investigator Cormoran Strike.

The mystery begins when model Lula Landry dies after falling from a London apartment balcony. Although the death is treated as suicide, Lula’s brother hires Strike to investigate. The case introduces Strike’s professional methods and his working relationship with Robin Ellacott.

The book was initially received as the work of an unknown former military investigator named Robert Galbraith. Rowling’s authorship was revealed later in 2013. The title is drawn from the cuckoo’s distinctive reproductive behavior, in which it lays eggs in the nests of other birds. The novel launched the Cormoran Strike series, which continued with The Silkworm, Career of Evil, and later installments.
