The Duchess of Duke Street

Louisa and Lottie are at loggerheads -- Louisa wants her daughter to be a proper lady, as befits the daughter of a Viscount. Lottie is confident that she has the talent and the looks to become a major musical star of the London stage.

Lottie returns to the Bentinck from finishing school in Switzerland for a bit of a holiday and has her art teacher, Miss Olive Bradford, in tow. Lottie has become quite the young lady, having learned the rules of high society and losing her Yorkshire accent. The Major takes quite an interest in Miss Bradford but Louisa warns him that she is an old maid who may be out to get her hooks into him. Lottie also finds a beau, hotel guest Howard Blenkiron who takes an interest in her from their first meeting.

While a few of the staff know of Lottie's origins, others have set their tongues wagging about just why this young girls seems to be staying at the Bentinck. Louisa wont put up with it and sets out to end the gossip. Mary meanwhile takes an interest in her and invites her to tea with her friend Brian, the violin player. He immediately takes an interest in Lottie and grates at the constant stream of orders from Mary.
