British actress perhaps best known for the TV series Outnumbered, My Mother and Other Strangers, and Sense and Sensibility, and the films Mr Holmes and The Bank Job. She is the daughter of actress Anna Carteret and director Christopher Morahan, and her partner is fellow actor Blake Ritson.
The story is set in 1947, following a long-retired Holmes living in a Sussex village with his housekeeper and rising detective son. But then he finds himself haunted by an unsolved 50-year old case. Holmes' memory isn't what it used to be, so he only remembers fragments of the case: a confrontation with an angry husband, a secret bond with his beautiful but unstable wife.
After overhearing a shocking secret, precocious orphan Lyra Belacqua trades her carefree existence roaming the halls of Jordan College for an otherworldly adventure in the far North, unaware that it's part of her destiny.
