'So that's how you treat girls who are reduced to giving themselves for money, is it? And what about afterwards? Say you've put the wretched girl in the family way. I suppose that's no concern of your Lordship's?'

'Really, Margot!' he protested. 'I can't think what's got into you. A tart is a tart, and is doing a job of work like any other, even if at times it is not a very pleasant one. It is up to her to learn how to take care of herself. If she doesn't bother and gets caught, you can't hold the man responsible.'

'As he did it, he is.'

'I don't agree. If a chap is having an affair with a decent girl that, of course, is different. It is up to him to see that nothing goes wrong, and should they have the bad luck to have an accident, obviously it's his responsibility to get her out of trouble. Listen, I'll give you a parallel. When I was younger and lived in . . . out in Kenya, I often used to ride for other people in steeplechases. Say an owner had a really fractious horse and asked me as a favour to ride him, if the brute had thrown me and I'd broken a leg I'd have had the right to expect the owner to cough up my doctor's fees and hospital expenses. But if he had paid me for the job, and I'd taken the risk for money, it wouldn't even have occurred to me to ask the owner to foot the bill. In the same way, with tarts, getting in the family way is simply an occupational risk; that's all there is to it.'

'But supposing the girl is young and ignorant?'

He shrugged. 'If she's been paid I don't see that that makes much difference. These girls always have older friends to whom they can go for advice, or know of some old woman who'll do the necessary. But what beats me is why you should have become so het-up about all this.'

Mary saw the red light. She had already been dangerously near to stating her own case. If she pursued the subject further it might easily ring a bell in his mind and cause him to recognize her. Then goodbye to all hope of getting her own back on him. With an effort she pulled herself together and said in a calmer voice. 'You are quite right. It is only that I'm sorry for girls who have to earn their living that way and, as a woman, resent the fact that men's lust should force them to it.'
