Mrs Cusack-Bremmil loses her baby, and her grief estranges her husband's affections. Mrs Hauksbee sees the situation and flirts outrageously with him. Gossip reaches Mrs Cusack-Bremmil, and she, deciding that the memory of a dead child is not worth a lost husband, buys a magnificent new frock, and attends a ball at which she is not expected. She makes a superb entrance, and carries her husband off again. This is the first appearance of Mrs Hauksbee, described here as 'a little, brown, thin, almost skinny, woman, with big, rolling, violet-blue eyes, and the sweetest manners in the world.'
