The bestselling author of The Bolterreturns with a delicious novel about two determined women whose lives collide in the halls of a pedigreed London town home. When eighteen-year-old Grace Carlisle arrives in London in 1914, she's unable to fulfill her family's ambitions and find a position as an office secretary. Lying to her parents and her brother, Michael, she takes a job as a housemaid at Number 35, Park Lane, where she is quickly caught up in lives of its inhabitants, most especially those of its privileged son, Edward, and daughter, Beatrice. Beatrice has just returned from America after being unceremoniously jilted by her fiancé, and, desperate to find a new purpose, has joined the radical suffragist movement and struck up an intriguing romance with an impassioned young lawyer. But unbeknownst to both of the young women, the choices they make will connect their chances at future happiness in dramatic and inevitable ways.
