A fairly honourable defeat.

"One of Iris Murdoch’s more successful novels, A Fairly Honourable Defeat combines elements of realism and allegory to create a commentary on the moral shortcomings of the individual and society. The book opens as Hilda and Rupert Foster, an ostensibly happily-married couple, anticipate their forthcoming twentieth anniversary party." ([Source][1])
