Cormoran Strike is a private detective. He operates out of a tiny office in London’s Denmark Street. Grainger’s character Robin is his assistant. While she begins as a temporary secretary, managing Strike’s chaotic life, she will soon become involved with his cases. It is then she will begin to see her true potential.

Holliday Grainger says: “I’m thrilled to be joining the talented creative team behind The Strike Series, especially with the role of Robin Ellacott. Her grounded strength and intelligence is going to be a joy to explore. I can’t wait to dive straight into the wit and grit of Strike’s cannily well observed London.”

J.K. Rowling says: “I couldn’t be more delighted about the casting of Holliday Grainger, who brought my Robin to perfect onscreen life during her audition. We’ve now secured two superb actors in the lead roles and I think they will create something very special together.”

Rowling is executive producing The Strike series, with Neil Blair, Ruth Kenley-Letts, and Elizabeth Kilgarriff. Ben Richards is writing the scripts for The Cuckoo’s Calling and The Silkworm. Tom Edge will script Career of Evil. Michael Keillor will direct The Cuckoo’s Calling. Jackie Larkin is producing.

Grainger’s other television work includes Lady Chatterley’s Lover, Bonnie & Clyde, and The Borgias.
