Who Was That Lady? - S1.E5

Deirdre St. John Featherstone-Haugh is stunning, elegant, and cunning - and she has her sights set on Norman. Not out of attraction, but because she requires a partner in crime to secure a large sum of money. With amnesia, Norman is unwittingly drawn into her deceitful scheme. He is forced to masquerade as a prominent aristocrat and a former head-boy of Eton.
