On 10 December 2014, it was announced that the Cormoran Strike novel series, written by J. K. Rowling under the pseudonym Robert Galbraith, would be adapted for television by the BBC, for broadcast on BBC One, beginning with The Cuckoo's Calling. Two years later, it was confirmed that the series would total seven episodes of sixty minutes, with shooting to begin in London in the autumn of 2016.^[11] Tom Burke was announced in the role of Cormoran Strike in September 2016,^[12] while Holliday Grainger was announced in the role of Robin Ellacott in November 2016.^[13]

Ben Richards adapted The Cuckoo's Calling, and Tom Edge adapted The Silkworm, Career of Evil, Lethal White and Troubled Blood. Richards stated that the series is "very different tonally and visually from other crime dramas." He compared Strike to the British detective television show Morse. Similarly, Edge commented that "people use old-fashioned as a pejorative word, but to me that's part of why these books, and, I hope, the TV series, works so well."^[14]

The Cuckoo's Calling received generally positive reviews from critics. Rotten Tomatoes gave it an approval rating of 85%, based on 20 reviews, and an average score of 6.8/10.

Similarly, the adaptation of The Silkworm was met with positive reviews, with critics again praising Burke and Grainger's performances.^[23][24] However, the first episode was criticised for showing a suicide scene on World Suicide Prevention Day, making some viewers claim that this scene was insensitive.^[25]
