‘Was there a battle, then?’ Mr Cullen asked.

‘No,’ Grant said. ‘Scotland stepped thankfully on to England’s band-wagon, and fell heir to all the benefits. Colonies, Shakespeare, soap, solvency and so forth.’

‘I hope Mr Brown doesn’t go lecture-touring in the States,’ Zoë said, half asleep.

‘He will,’ Grant said. ‘He will. All vociferous minorities go lecture-touring in the States.’

‘It will give them very wrong ideas, won’t it?’ Zoë said mildly. Grant thought with what a blistering phrase Laura would have expressed the same idea. ‘They have the oddest ideas. When David and I were there, the year before he was killed, we were always being asked why we didn’t stop taxing Canada. When we said we had never taxed Canada they just looked at us as if we were telling lies. Not very good lies, either.’

From Mr Cullen’s expression Grant deduced that he too had had ‘odd’ ideas about Canadian taxation, but Zoë’s eyes were closed. Grant wondered if Mr Cullen realised that Zoë was quite unaware that he was an American; that it had not occurred to her to consider his accent, his nationality, his clothes or any personal thing about him. She had accepted him as he stood, as a person. He was just a flyer, like her brother; someone who had turned up in time to share their picnic and who was pleasant and interesting to talk to. It would not occur to her to pigeon-hole him, to put him in any special category. If she was conscious at all of his narrow a’s she no doubt took him for a North-countryman.

He looked at her, half asleep there in the sun, and thought how beautiful she was. He looked across at Mr Cullen and saw that he too was looking at Zoë Kentallen and thinking how beautiful she was. Their glances met and ran away from each other.

But Grant, who last night could imagine no greater felicity than to sit and look at Zoë Kentallen, was conscious now of a faint impatience with her, and this so shocked him that he took it out, in his self-analytical way, to examine it. What flaw could there be in this divinity? What imperfection in this princess from a fairy-tale?

‘You know very well what’s wrong,’ said that irreverent voice in him. ‘You want her to get the hell out of here so that you can find out about B Seven.’

And for once he did not try to contradict the voice. He did in brutal fact wish that Zoë would ‘get the hell out of here’. The Zoë whose very presence had made magic of yesterday afternoon was now an encumbrance. Tiny prickles of boredom chased each other up and down his spine. Lovely, simple, heavenly Zoë, do get a move on. Creature of delight and princess of my dreams, go away.
