Morstan Vs Milverton was the 3rd and final episode of the 1st series of The Mary Morstan Mysteries. It originally ran in 5 parts between December 23rd 2012-January 12th 2013.
In the episode, following the receipt of some very saucy and scandalous letters between Mrs. Forrester and her former butler, Moriarty commissions Milverton to administer the blackmail on his behalf, but unfortunately for him, Mrs. Forrester just happens to be the best friend of Mary Morstan, who vows to fight the threat any way she can.
This is one of Lexi Wolfe's personal favourite episodes. In the companion guide to the show, she wrote:
"This, if anything, has to be my favourite one that we have done thus far. I’ve always been a strong supporter of LGBT rights and I fell in love with Ross’s speech that Mary has when she gives Milverton some consideration for what would have, back at that point in history, been outlawed and so strongly penalised. I felt more in touch with Mary as a forward-thinking woman when we filmed this than I ever had previously. Touching on an issue I’ve always felt so strongly about was very enjoyable for me.
