The Duchess of Duke Street

A feisty, determined, kind hearted young woman embarks on her career 'to be the best cook in England,' when she's employed in the London home of a well connected aristocrat.

Hardly flattered and severely compromised, Louisa has caught the eye of the Prince of Wales and is pressed into marrying Augustus Trotter.

All bets are off when HRH becomes His Majesty, King Edward VII and Louisa and Augustus must plan what lies ahead for them.

Heavily in debt, Louisa is on a juggernaut that lands in her in the hospital, after she collapses from exhaustion. But, that handsome devil and consoling angel, Charlie Tyrrell, devises a plan to save her hotel.

With Charlie Tyrell now in residence as the first guest, the hotel is now officially open to the public. Louisa has set a high standard for herself and is relying on word of mouth among the right kind of people to bring in the clientèle. Charlie invites an attractive, but married, woman for dinner in his rooms only to have her leave when she realizes she is the only guest. He invites Louisa to join him and unexpectedly, they soon are lovers. When Charlie must leave for America, Louisa is heartbroken but she also is pregnant. At the appropriate time, she leaves the hotel with Mary in charge to go and give birth. Soon Charlie is back and completely unaware of what has been going on, tracks her down. He also has a proposition on how to care for their child

A con artist, posing as a Baron, dupes a greedy American guest and seduces a lonely young bride, as a vigilant and intrigued Louisa monitors his every move.

Louisa's only brother, ne'er do well Arthur, returns to London after a decade. Her mother pressures Louisa into offering him a job at the Bentinck, running the risk of alienating the rest of her staff.

When two high spirited Oxford students play a prank on Louisa, she goes along with the fun and finds a Professor of Classics pitching the woo to her. Meanwhile, Lord and Lady Haslemere come down from Yorkshire to shop for their London home.

Louisa takes a callow chauffeur in tow and tries to turn him into a 'proper gentleman,' when his kind, elderly and wealthy employer dies suddenly and leaves him the bulk of her estate.

Louisa visits Lord and Lady Haslemere in Yorkshire and finds a bleak and desperately unhappy household.

Louisa urges Charlie to get on with his life and a smooth and very suave actor beds Violet, who promptly gets the sack.

With the outbreak of the Great War, the staff are galvanized to help in the effort and keep the hotel running as usual. Louisa takes in a Belgian refugee, a master pastry chef. Charlie enlists and leaves a worried Louisa as he departs for France .
