Strike is the surname of J.K. Rowling’s protagonist in the Cormoran Strike novels.
Cormoran Strike is a private detective and former military investigator who operates in London. The character first appeared in The Cuckoo’s Calling, published in 2013 under Rowling’s pseudonym Robert Galbraith. Strike is the son of the rock star Jonny Rokeby and Leda Strike, a background that gives him a connection to public attention despite his investigative work.
Robin Ellacott begins as Strike’s temporary secretary and becomes his professional partner. Their evolving working relationship is a major thread across the series, but Robin is not the protagonist named in the series title.
“Galbraith” is the author pseudonym, while “Cormoran” is Strike’s first name. These distinctions matter because the books’ marketing presents Robert Galbraith as the credited writer and Cormoran Strike as the detective at the center of the stories.
