Durraghglass is a beautiful mansion in Southern Ireland, now crumbling in neglect. The time is the present - a present that churns with the bizarre passions of its owners' past. The Swifts - three sisters of marked eccentricity, defiantly christened April, May and Baby June, and their only brother, one-eyed Jasper - have little in common, save vivid memories of darling Mummy, and a long lost youth peculiarly prone to acts of treachery.
Into their world comes Cousin Leda from Vienna, a visitor from the past, blind but beguiling - a thrilling guest. But within days, the lifestyle of the Swifts has been dramatically overturned - and desires, dormant for so long, flame fierce and bright as ever.
