He strode away, disappearing quickly from sight over the brow of a hill, and with a small sigh of contentment she tucked her feet under her on the improvised cushion and lit a cigarette. She had had a busy morning, and was really more tired than she knew. First of all there had been the car to clean, then there were flowers to be arranged for the house, and after that various small shopping errands had cropped up, so that Ann had found herself very fully occupied until at length, accompanied by Sir Philip, Lady Susan had departed for Evian. She wondered fugitively how the pair were enjoying themselves. It was very pleasant sitting there. The huge boulder against which she leant sheltered her from the wind and the spot was bathed in brilliant sunshine. She finished her cigarette and lapsed into a brown study provoked by Tony's sudden question: "What will happen if one day you--or Robin--should get married?" She had never asked herself that question. It was so much an understood thing between brother and sister that, as soon as Robin found a sufficiently remunerative post, they should live together, that any alternative had not entered her head. But now she came to think of it, of course it was quite possible that Robin might some day meet the woman whom he would want to marry. Her mouth twisted in a little wry grimace of distaste. She was sure she should detest any woman who robbed her of her brother. And if such a thing happened, she would certainly take herself off and live somewhere else. Nothing would ever induce her to remain in a married brother's house--an unwanted third. There would always be one avenue of escape open to her, she reflected ironically--by way of her own marriage with Tony. She wished it were possible to fall in love to order! It would simplify things so much. As Tony's wife she felt sure she could keep him straight and so fulfil the trust Virginia had imposed on her. He had always shown himself sensitively responsive to her influence--like a penitent boy if she scolded him, radiant if he had won her approval. And he had a very special niche of his own in her heart. Next to Robin, there was no one she loved more. ... A sudden cloud across the sun roused her to the fact that she had been sitting still for some time, and that, at that altitude, the air held all the mountain keenness. She felt chilled, and scrambled up hastily to her feet. She would go to the crest of the hill and signal to Tony that she was ready to return.
