What was less comprehensible, however, was how Robbie imperiously raised his hand now, as though issuing a command which Cecilia dared not disobey. It was extraordinary that she was unable to resist him. At his insistence she was removing her clothes, and at such speed.
She was out of her blouse, now she had let her skirt drop to the ground and was stepping out of it, while he looked on impatiently, hands on hips. What strange power did he have over her? Blackmail? Threats? Briony raised two hands to her face and stepped back a little way from the window. She should shut her eyes, she thought, and spare herself the sight of her sister’s shame. But that was impossible, because there were further surprises. Cecilia, mercifully still in her underwear, was climbing into the pond, was standing waist deep in the water, was pinching her nose- and then she was gone. There was only Robbie, and the clothes on the gravel, and beyond, the silent park and the distant, blue hills.
