Cormoran Strike’s investigative partner is named Robin in J.K. Rowling’s crime series.
Robin Ellacott first works with Strike as a temporary secretary in The Cuckoo’s Calling. Her organizational ability, intelligence, and interest in investigation lead her to become increasingly involved in cases rather than remaining only an office assistant.
Across the series, Robin develops as an investigator while navigating professional pressures and a complicated personal life. Her partnership with Strike is central to the books’ mystery plots, and their contrasting personalities shape the series’ long-running narrative.
The character is sometimes identified only by her surname, Ellacott, or confused with other Robin characters in British crime fiction. In Rowling’s Cormoran Strike books, Robin is the partner whose professional relationship with Strike evolves from administrative work into investigative collaboration.
