Sian Brooke Talks Playing Eurus Holmes
Actress Sian Brooke fooled a lot of people in her portrayal of four different characters in the fourth series of Sherlock. We first meet her in The Six Thatchers as Elizabeth, the girl on the bus that John Watson texts with. Then in The Lying Detective, she plays both a version of Culverton Smith's daughter Faith and John's new psychiatrist Issa. While in the third episode, The Final Problem, she is revealed to be the third Holmes sibling, Eurus Holmes. Brooke talks about playing the four roles and how having worked with Benedict Cumberbatch in Hamlet helped with the chemistry between the two.
