The Dowager Duchess of Royston made a bet with her friends that her handsome grandson Justin St. Just would announce his engagement in the next two weeks. The task is not easy since the young Duke had no intention of getting married. But his grandmother has started a brilliant intrigue, which her young companion Eleanor watches with bated breath. She has been in love with Justin for a long time, which she doesn’t even admit to herself. And her situation is hopeless: the girl has neither money nor a decent background, but she is smart and unusually pretty.
