Which pseudonymous novel by J.K. Rowling features private detective Cormoran Strike’s first case?

The Cuckoo’s Calling is the pseudonymous J.K. Rowling novel featuring Cormoran Strike’s first case.

Published in 2013 under the name Robert Galbraith, the novel introduces Cormoran Strike, a private detective in London. Strike investigates the death of model Lula Landry, whose death was initially treated as a suicide. His temporary secretary, Robin Ellacott, becomes an important part of the investigation.

The novel was marketed as the work of a first-time crime writer until Rowling’s authorship was exposed. After the revelation, sales increased sharply, but the book continued to be published under the Galbraith name for the series.

The Cuckoo’s Calling is the first of several Strike mysteries. Its sequels include The Silkworm, Career of Evil, Lethal White, Troubled Blood, The Ink Black Heart, and The Running Grave. The series is sometimes described as Rowling’s crime-fiction project rather than a continuation of Harry Potter.
