The Minotaur - Barbara Vine - Bog

Kerstin Kvist enters crumbling Lydstep Old Hall to live with the Cosways and to act as nurse to John: a grown man fed drugs by his family to control his lunatic episodes. But John's strangeness is grotesquely mirrored in that of his four sisters who roam the dark, mazy Essex country house under the strict gaze of eighty-year-old Mrs Cosway.
