‘You should go to bed with one of us. As soon as possible. There’s no better cure for an infatuation than that,’ said Willi, in the brutally good-humoured voice he used when speaking out of his role as sophisticated Berliner. Ted grimaced, and removed his arm, making it clear that he was not prepared to ally himself with such cynicism, and that if he went to bed with Maryrose it would be out of the purest romanticism. Well, of course it would have been.

‘Anyway,’ observed Maryrose, ‘I don’t see the point. I keep thinking about my brother.’

‘I’ve never known anyone be so completely frank about incest,’ said Paul. He meant it as a kind of joke, but Maryrose replied, quite seriously, ‘Yes, I know it was incest. But the funny thing is, I never thought of it as incest at the time. You see, my brother and I loved each other.’

We were shocked again. I felt Willi’s shoulder stiffen, and I remember thinking that only a few moments before he had been the decadent European; but the idea that Maryrose had slept with her brother plunged him back into his real nature, which was puritanical.

There was a silence, then Maryrose observed: ‘Yes, I can see why you are shocked. But I think about it often these days. We didn’t do any harm, did we? And so I don’t see what was wrong with it.’

Silence again. Then Paul plunged in, gaily: ‘If it doesn’t make any difference to you, why don’t you go to bed with me, Maryrose? How do you know, you might be cured?’

Paul still sat upright, supporting the lolling child-like weight of Jimmy against him. He supported Jimmy tolerantly, just as Maryrose had allowed Ted to put his arm around her. Paul and Maryrose played the same roles in the group, from the opposite sides of the sex barrier.

Maryrose said calmly: ‘If my boy-friend in the Cape couldn’t really make me forget my brother, why should you?’

Paul said: ‘What is the nature of the obstacle that prevents you from marrying this swain of yours?’

Maryrose said: ‘He comes from a good Cape family, and his parents won’t let me marry him, because I’m not good enough.’

Paul allowed himself his deep attractive chuckle. I’m not saying he cultivated this chuckle, but he certainly knew it was one of his attractions. ‘A good family,’ he said derisively. ‘A good family from the Cape. It’s rich, it really is.’

This was not as snobbish as it sounds. Paul’s snobbishness was expressed indirectly, in jokes, or in a play on words. Actually he was indulging his ruling passion, the enjoyment of incongruity. And I’m not in a position to criticize, for I daresay the real reason I stayed in the Colony long after there was any need was because such places allow opportunity for this type of enjoyment. Paul was inviting us all to be amused, as he had when he had discovered Mr and Mrs Boothby, John and Mary Bull in person, running the Mashopi hotel.
