Holliday Grainger will play the female lead in Strike, a series of new BBC event dramas based on the crime books of J.K. Rowling.

As previously reported, the first three thrillers she wrote under the pseudonym Robert Galbraith are being adapted for television, with shooting due to begin this month.

Tom Burke, best known for his role in The Musketeers, will play private eye Cormoran Strike, while Grainger – last seen here on DVD in The Finest Hours – will take on the role of his assistant Robin Ellacott. In the books, she is originally taken on as a temp, but soon gets becomes involved with his investigations.

“I’m thrilled to be joining the talented creative team behind the Strike series, especially with the role of Robin Ellacott,” she says. “Her grounded strength and intelligence is going to be a joy to explore.”

Rowling adds: “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.”

The first Galbraith book, The Cuckoo’s Calling, will be adapted into a 3 x 60 minute mini-series, while The Silkworm and Career of Evil will both be two-parters.

Rowling’s fans, meanwhile, are counting down the days to the arrival of Fantastic Beasts And Where To Find Them, which opens in cinemas in just under a fortnight.
