Fru Inés is a city novel, vividly evoking the sights, sounds and smells of nineteenth-century Constantinople. The city is a hub, a meeting point of East and West, where privileged Europeans enjoy a cossetted existence screened from the tumult and misery of the streets. One of the privileged is Ines, a Spanish Levantine from Alexandria, whose marriage to a Swedish consul has brought her a life of enviable luxury; but behind the polished facade she is lonely and unfulfilled, trapped in a loveless marriage. Her yearning for passion leads her to embark on an affair with a naive young Swede, Arthur Flemming; but their love is threatened from the start by portents of disaster and the threat of discovery, and Inés is inexorably drawn to seek rescue from the sordid dealers from whom she had been so careful to keep aloof.
