Danish actor Lars Mikkelsen has landed a villainous new role in the upcoming third season of hit Tv series Sherlock.

The star of cult Danish drama The Killing will portray the title character in the Tv adaptation of Arthur Conan Doyle's crime novel The Adventure of Charles Augustus Milverton, about a blackmailer who cons wealthy nobles.

Benedict Cumberbatch plays the modern version of Doyle's literary supersleuth, Sherlock Holmes, on the popular Bbc show, opposite Martin Freeman.
