Sparrow Hall by John Aspinall
When his parents and uncle - a fatal triangle - self-destruct in 1982, Damien Frobisher, a well-meaning upper class socialist, inherits the huge, run-down Sparrow Hall. Damien would be more than happy to sell his embarassing inheritance to developers, but his domineering and sexually voracious wife Julie sees this as the perfect opportunity to found a commune, based on the socialist principles close to both their hearts. However the illassorted group of losers and oddballs they manage to assemble seems doomed from the outset. As anarchy becomes the new policy and then New Ageism begins to creep in, Julie's affairs and barely concealed contempt for her husband force Damien to retreat even further into his shell, until the Sparrow Hall community implodes once again in a fatal fire. But was it an accident, murder, or suicide?
