GOOD BEHAVIOUR by Molly Keane

We kept our heads above the morass, stifled screaming despairs only by the exercise of Good Behaviour. Behind the gates of Temple Alice, the aristocratic St Charles family is sinking into a state of decaying grace. Aroon, the unlovely daughter of the house, silently longs for affection - which she receives neither from her icy mother nor her hunting-obsessed father.

But no crumbling codes of conduct can save the members of the St Charles family from their own dark secrets and repressed cruelties . . .
