LONDON — The BBC is to adapt J.K. Rowling’s Cormoran Strike crime novels, which were written under the pen name of Robert Galbraith, as a series.

The books center on Cormoran Strike, a former army officer turned private investigator.

The first book in the series to be adapted will be “The Cuckoo’s Calling,” which will air on the broadcaster’s flagship channel, BBC One.

In “The Cuckoo’s Calling,” Strike looks into the supposed suicide of a model, who plunges to her death from a balcony in London’s high-class neighborhood Mayfair. Strike suspects it was murder.

The series will be produced by Bronte Film and TV, which is run by Rowling and Neil Blair. Bronte also produced the adaptation of Rowling’s “The Casual Vacancy,” which was commissioned by the BBC and HBO, and airs on BBC One in February.

Rowling revealed the news about the Cormoran Strike series herself, tweeting: “My friend @RGalbraith’s first novel is going to be a TV drama on @BBCOne. He’s very excited, but expressing it with characteristic silence.”

She added: “I am exactly as excited as he is.”

Rowling will be advising on the project, “with the number and length of episodes to be decided once the creative adaptation process has formally begun,” the BBC said. Casting is underway.

Danny Cohen, director of BBC television, said: “It’s a wonderful coup for the BBC to be bringing J.K. Rowling’s latest books to the screen. With the rich character of Cormoran Strike at their heart, these dramas will be event television across the world.”
