In her gloomy mausoleum of a home, the terrifying matriarch Great Granny Webster spends her days sitting bolt upright in a Victorian chair, entirely alone except for her one-eyed maid - and her orphaned great-granddaughter, sent to stay for the sea air.

She presides over three generations of ill-fated women, and a twisted family history which spools back through hedonistic 20s London to a crumbling aristocratic pile where two children are kept silently hidden in a distant wing.

This macabre, viciously funny, partly autobiographical novel cuts to the bone of a dysfunctional dynasty, and captures Blackwood at her pitch-black best.
