Mr. and Mrs. Lawrence Kirbridge return from their honeymoon and set up their new household in nearby Greenwich.

Sarah tells James she's having his baby and the Bellamys make provisions to avoid a major scandal.

Things have not improved in the Kirbridge household. It turns out they have yet to consummate their marriage. Lizzie, unaware she's married to a homosexual, is miserable and angry, making Lawrence miserable, too. Realising he cannot fulfil that need for her, Lawrence decides to enlist the help of a friend to step in as proxy.

Elizabeth comes home for Christmas without Lawrence. The Bellamys face another family crisis when it is discovered that Elizabeth is expecting a baby.

There is great excitement among the servants when King Edward VII attends a supper party at Eaton Place. During the evening the arrival of an unexpected visitor creates an emergency below stairs.

Thomas is approached by a blackmailer who claims to have love letters from Lady Marjorie to Captain Hammond.

The brothers of both Richard and Hudson are visiting, causing both men to do things they otherwise would not. For Hudson, it means putting on airs, and for Richard, the visit causes him to snoop; an action he considers beneath him.

Elizabeth returns home with her newborn daughter, Lucy, and the very disagreeable and old Nanny Webster, to look after "Baby".

Everyone's nerves are frazzled when Lord Southwold dies, Lady Southwold and her companion, Miss Hodges, spend some time with Richard and Lady Marjorie and a valuable diamond brooch goes missing.

Elizabeth joins the suffragette movement, but in her effort to protect her, Rose is imprisoned.

The Bellamys are in shock when they learn that Eaton Place, which is part of the Southwold estate, must be sold in order to satisfy the terms of the deceased Lord Southwold's will. Adding to their worries is news of Elizabeth's involvement with Julius Karekin, a man they strongly disapprove of, but in the end, the relationship proves very beneficial.

Sarah is pregnant with Watkins' baby and Lady Marjorie has run out of patience with both of them.

Elizabeth's affair with Julius is over, James returns to England with his fiancée, Phyllis, and a major event marks the end of an era.
