'I think it's gay and fun.'
'It's charming,' I said.
In less than half an hour we had reached the main Ismailia-Jerusalem road. Mr Aziz turned the Rolls on to the black tarmac strip and headed for the filling-station at seventy miles an hour. In a few minutes we would be there. So now I tried moving a little closer to the subject of another visit, fishing gently for an invitation. 'I can't get over your house,' I said. 'I think it's simply wonderful.'
'It is nice, isn't it?'
'I suppose you're bound to get pretty lonely out there, on and off, just the three of you together?'
'It's no worse than anywhere else,' he said. 'People get lonely wherever they are. A desert, or a city - it doesn't make much difference, really. But we do have visitors, you know. You'd be surprised at the number of people who drop in from time to time. Like you, for instance. It was a great pleasure having you with us, my dear fellow.'
'I shall never forget it,' I said. 'It is a rare thing to find kindness and hospitality of that order nowadays.'
I waited for him to tell me that I must come again, but he didn't. A little silence sprang up between us, a slightly uneasy little silence. To bridge it, I said, 'I think yours is the most thoughtful paternal gesture I've ever heard of in my life.'
'Mine?'
'Yes. Building a house right out there in the back of beyond and living in it just for your daughter's sake, to protect her. I think it's remarkable.'
I saw him smile, but he kept his eyes on the road and said nothing. The filling-station and the group of huts were now in sight about a mile ahead of us. The sun was high and it was getting hot inside the car.
'Not many fathers would put themselves out to that extent,' I went on.
Again he smiled, but somewhat bashfully, this time, I thought. And then he said, 'I don't deserve quite as much credit as you like to give me, really I don't. To be absolutely honest with you, that pretty daughter of mine isn't the only reason for my living in such splendid isolation.'
'I know that.'
'You do?'
'You told me. You said the other reason was the desert. You loved it, you said, as a sailor loves the sea.'
'So I did. And it's quite true. But there's still a third reason.'
'Oh, and what is that?'
He didn't answer me. He sat quite still with his hands on the wheel and his eyes fixed on the road ahead.
'I'm sorry,' I said. 'I shouldn't have asked the question. It's none of my business.'
'No, no, that's quite all right,' he said. 'Don't apologize.'
I stared out of the window at the desert. 'I think it's hotter than yesterday,' I said. 'It must be well over a hundred already.'
'Yes.'
I saw him shifting a little in his seat, as though trying to get comfortable, and then he said, 'I don't really see why I shouldn't tell you the truth about that house. You don't strike me as being a gossip.'
'Certainly not,' I said.
We were close to the filling-station now, and he had slowed the car down almost to walking-speed to give himself time to say what he had to say. I could see the two Arabs standing beside my Lagonda, watching us.
'That daughter,' he said at length, 'the one you met - she isn't the only daughter I have.'
'Oh, really?'
'I've got another who is five years older than she.'
'And just as beautiful, no doubt,' I said. 'Where does she live? In Beirut?'
