Sarah is not averse to romantic adventures and so becomes the patron of the young country lord Arthur Masham, unceremoniously making him an ensign in the queens guards. However, Henry St. John sees through the plan, knowing that Masham is engaged to Abigail, a jealous shop assistant in a jewellery store, who he wants to win for himself.Masham kills a very rich cousin of Henry in a duel. Henry thus inherits a huge fortune and the title Lord Bolingbroke. He wins the next round of intrigues, getting a position in the queens court for Abigail and thus gaining influence there for himself. Via Abigail he learns that the queen has her eye on Masham without him being aware of it. As a signal for a planned rendezvous, she wants to pass him a glass of water during a ball. Henry thus explains to Sarah that she has a rival, but does not name names. However, at the queens next ball she vies with the queen for Mashams favour and then panics, meaning both she and Masham have to resign their roles as the queens confidantes. ........
