Move aside wizards, J.K. Rowling's private detective Cormoran Strike is headed to the screen. 

HBO has acquired U.S. and Canadian rights to a limited TV series based on the Harry Potter creator's bestselling trio of gritty, gruesome mystery novels about a war vet-turned-private detective. 

Cormoran Strike is being produced by the BBC, which first announced plans for the series in 2015.

It will star British stage and screen actor Tom Burke as the title character: a troubled former investigator of the British military's Special Investigative Branch who lost a leg while serving in Afghanistan. Now working as a private investigator out of a tiny London office, Strike becomes involved in solving a trio of cases that have stumped police.

Burke has appeared in recent BBC productions of War and Peace as well as the British public broadcaster's series The Musketeers. No other casting has yet been announced.

The Cuckoo's Calling, the first novel in the series, will unspool as three one-hour episodes. The second and third books — The Silkworm and Career of Evil, respectively — will each be divided into two one-hour episodes. Filming is set to begin this fall. 

Secret's out

Rowling initially published the first book in 2013 under the pseudonym Robert Galbraith, with her secret identity subsequently leaked by a partner at a British law firm that worked with the author. She published the follow up novels in 2014 and 2015, with a fourth book expected to emerge in 2017.

Rowling's first adult-targeted novel, the social drama The Casual Vacancy, was also filmed by the BBC and carried by HBO. 

Meanwhile, the first instalment of the Fantastic Beasts and Where to Find Them film series, the latest spin-off from her blockbuster Harry Potter wizarding stories, hits theatres in mid-November. 

Rowling also continues to expand the wizarding world she created through writing for her website Pottermore.
