The series received critical acclaim and featured fellow young actress Lily James also known for her period dramas. The Daily Express said: "Rising star Tuppence Middleton takes on the role of the delightfully evil Hélène Kuragina, who is one half of the incestuous duo. Audiences witnessed her brother getting a little too intimate with his sibling in the first episode before she turned her attentions to Pierre and dug her claws into him. She is a vile character who will use and abuse Pierre without giving him a second thought, to stop the beautiful Natasha (Lily James) Pierre real love marrying him." She has in interviews described herself as shy. "I liked to be in my own company, so when I came home from school, I'd just go up to my room and hang out by myself. I wouldn't really have friends over or go to see friends much. I was very, very shy in public and school, and quite loud and brash at home. As I got older, I auditioned for drama school and shocked myself by getting in."
