What is the name of the detective in the 'Cormoran Strike' series?

The detective in the Cormoran Strike series is Cormoran Strike. He is a London-based private investigator and the central character of crime novels written by J. K. Rowling under the pen name Robert Galbraith.

Strike first appears in The Cuckoo's Calling, published in 2013. A former Royal Military Police Special Investigation Branch investigator, he leaves military service after losing part of one leg in Afghanistan and establishes a private detective agency. His professional experience gives him investigative skill, while his financial and personal difficulties add a more grounded dimension to the stories.

Robin Ellacott becomes Strike's temporary secretary at the beginning of the series and gradually develops into his investigative partner. Their working relationship is a major continuing thread. Matthew Cunliffe is Robin's fiancé and later husband for part of the series, while Charlotte Campbell is Strike's former fiancée; neither is the detective.

The novels combine murder investigations with longer character arcs and the pressures of modern London life. The series has also been adapted for television as Strike, with Tom Burke portraying Cormoran Strike and Holliday Grainger playing Robin Ellacott.
