The Musketeers and War And Peace star Tom Burke will take on the role of Cormoran Strike in a new TV adaptation of JK Rowling's crime novels, which she wrote under the pseudonym Robert Galbraith.
The three event dramas will begin shooting in London this autumn and will air on BBC One.
The Cuckoo's Calling, The Silkworm and Career Of Evil will feature Tom as the war veteran turned private detective operating out of a tiny office in London's Denmark Street.
Though he's wounded both physically and psychologically, Strike's unique insight and his background as an SIB investigator prove crucial in solving three complex cases which have eluded the police.
The first Cormoran Strike book, The Cuckoo's Calling, was published in 2013 under the name of Robert Galbraith but it was later revealed that it was penned by the Harry Potter author.
JK said she is thrilled by Tom's casting, saying he is "a massively talented actor who'll bring the character to perfect life".
She added: "Cormoran Strike is pure joy to write and I can't wait to see Tom play him."
Tom said: "I'm overjoyed to be immersing myself in the role of Cormoran Strike, who is as complex as he is larger than life.
"I know I'm joining an extraordinary team of people on a series that for me is peppered with moments of real emotional depth and meticulously grounded in the page-turning momentum of these novels. Cormoran's world is rich and raw."
