JK Rowling wrote the ‘Strike’ series under the pseudonym, Robert Galbraith.
The detective novels about Cormoran Strike have been adapted into a BBC television drama starring Tom Burke.
The first adaptation of the series, 'The Cuckoo's Calling', has been released on DVD.
Tom Burke spoke to Toby Earle about his high calorie diet which got him into character as the grumpy detective Cormoran Strike for the popular series.
The third part of the story is coming to BBC One in 2018.
