Which detective is the main character in J.K. Rowling’s crime novels?

Cormoran Strike is the main detective in J.K. Rowling’s crime novels published as Robert Galbraith.

Strike is a private investigator based in London. The series begins with The Cuckoo’s Calling, in which he investigates the death of model Lula Landry. Strike’s work is shaped by his military police background and by physical injuries sustained while serving in Afghanistan.

Robin Ellacott becomes his secretary and investigative partner. Their professional relationship develops across the novels, making Robin an important continuing character rather than a one-book assistant.

The books are credited to Robert Galbraith, Rowling’s crime-fiction pseudonym. Although the stories are independent of Harry Potter, they share Rowling’s interest in detailed character relationships, clues, and long-running plot threads.
