Fans of J.K. Rowling in the US and Canada can sleep well knowing that the upcoming Cormoran Strike mini-series will air on HBO as well as BBC One. The novel series, written under the nom de plume Robert Galbraith, continues the 'Harry Potter' author's run of onscreen adaptations.

The speculation has been confirmed; the television adaptation to J.K. Rowling's latest novel series is coming to HBO, following in the footsteps of her 2012 book 'The Casual Vacancy' which aired as a limited series in the States in April 2015.

First announced in Fall 2015, the show has been in the works for two years and it was revealed in September this year that 'War And Peace' star Tom Burke would star as the surly private detective. No other stars have been announced as of yet, but filming begins in London this Fall and we can expect seven 60 minute episodes spanning the three books released so far: 'The Cuckoo's Calling', 'The Silkworm' and 'Career Of Evil'.

The story follows a former Special Investigation Branch detective turned private investigator named Cormoran Strike and his adventures with his assistant Robin Ellacott. Left with a prosthetic leg following his tour of duty in Afghanistan and with a bruised ego from a messy break-up, he has to put his personal problems behind him if he wants to solve a series of brutal murders. It's a difficult job, but at least it pays the bills.

J.K. Rowling acts as executive producer on the project through her own production company Brontë Film & TV. Meanwhile, Michael Keillor ('Line Of Duty', 'Critical') is due to direct the first episode at least, with Ben Richards writing the screenplays for 'The Cuckoo's Calling' and 'The Silkworm' episodes and Tom Edge doing 'Career of Evil'. 

A fourth installment of the novel series is expected to arrive in 2017.
