What is the name of J.K. Rowling’s detective-fiction protagonist?

J.K. Rowling’s detective-fiction protagonist is Cormoran Strike.

Strike is a private investigator and former Royal Military Police investigator who appears in Rowling’s crime novels published under the name Robert Galbraith. The first book, The Cuckoo’s Calling, follows his investigation into the death of a famous model.

Robin Ellacott becomes his temporary secretary in the first novel and develops into a central investigative partner. Their professional partnership is one of the continuing threads of the series, while each book presents a separate major case.

Cormoran Strike is distinct from Harry Potter, Rowling’s wizarding protagonist, and from Newt Scamander, a fictional magizoologist in the Wizarding World. The Strike books belong to the detective-fiction genre rather than children’s fantasy.
