This is a cut above the average Regency romance. Olivia and her brother-in-law don't get on, though they try to tolerate each other for the sake of Clara, Olivia's sister and Miles' wife; mainly they avoid each other. Olivia is a 'bluestocking' with no understanding of Polite Society or relationships between men and women; she certainly does not understand the physical problems between Miles and Olivia which have led Miles to take a mistress. Thus her condemnation of Miles' behaviour makes it much harder, after Clara's death, for them to accept that they need each other's help and comfort. The way in which Olivia eventually helps Miles to come to an understanding with his children is, in the end, the key to their understanding of each other.
Elizabeth Mansfield's writing is sensitive and reflective as she pictures for her readers the coming to sexual awareness of a young woman who, even more than most in her time, has been sheltered from knowledge of male-female relationships. A number of the arguments between Olivia and Miles are very funny, although others - as they are intended - are saddening as the two of them contrive to drive each other further away by their mutual misunderstanding and pride.
Recommended; I certainly intend to keep and re-read my copy.
