Which pseudonymous author wrote J.K. Rowling’s 2020 crime novel Troubled Blood?

Robert Galbraith wrote J.K. Rowling’s 2020 crime novel Troubled Blood.

Troubled Blood is the fifth novel in the Cormoran Strike series. Like the earlier books, it is credited to Robert Galbraith, Rowling’s pseudonym for this body of detective fiction. The story follows private investigator Cormoran Strike and Robin Ellacott as they investigate a long-unsolved disappearance.

The novel was published in 2020 and is substantially longer than many conventional crime novels. Its investigation reaches back decades, making historical evidence and memory important parts of the plot.

Robert Galbraith is the author name on the books, while J.K. Rowling is the person behind the pseudonym. Cormoran Strike is the detective character, not the author, and Jack Thorne and John Tiffany are associated with Harry Potter and the Cursed Child.
