Oystercatchers : Amy lies in a coma. Her older sister, Moira, comes to her in the evenings, sits beside her in a green-walled hospital room. Here, Moira confesses. She admits to her childhood selfishness which deeply hurt her family; to her savagery at boarding school; to the wild, bitter and destructive heart that she carried into her adult life. Moira knows this: that's she's been a poor daughter, and a deceptive wife. But it is as Amy lies half-dying that she sees the real truth: she's been a cruel sister, and it is this cruelty that has led them both here, to this hospital bed.
