Move over, Joan Watson: The woman is coming to "Elementary."
"Game of Thrones" star Natalie Dormer has been cast as Irene Adler, Sherlock Holmes' presumed dead former lover, on the CBS detective drama.
Dormer makes her first appearance on May 9, the season's penultimate episode, and returns the following week in the two-hour finale.
"We're moving to the next chapter in our show -- and in some ways, to a previous chapter in Holmes' story," executive producer Rob Doherty said in a statement. His unique adaptation Arthur Conan Doyle's iconic mystery series -- especially changing Dr. Watson's gender -- sparked controversy before "Elementary's" successful premiere.
"Irene Adler is perhaps the most pivotal relationship in Sherlock's life," added Doherty, "and I can't think of an actress better suited to the challenge than Natalie."
Dormer is developing a reputation for playing iconic characters: Before joining "Game of Thrones" as Margaery Tyrell, she lost her head on "The Tudors" as Anne Boleyn, Henry VIII's doomed second wife.
"Elementary" airs at 10 p.m. Thursdays on CBS.
