Thomas Lynch is a libidinous aesthete and non-achieving art historian in disgrace for his sexual misdemeanors. There seems to be only one means of redemption - the opportunity to prove his life-long theory of the existence of an uncatalogued Madonna by the great Venetian Renaissance master, Giovanni Bellini. Lynch's obsessive search at last brings him to Mawle, a run-down English country house owned by the Roper family in Berkshire. Here in his search for the picture, Lynch has to confront a multitude of paradoxes: of desire and eroticism, art and life, truth and lies.
