"Five per cent.!" shouted Mr. Caffyn. "Your mother was only getting three and a half per cent."
"Oh, please don't interrupt," Dorothy begged, "because this is getting very complicated. In that case mother owes me, roughly, about another two hundred and fifty pounds. However, we'll let that pass. You are both released from all responsibility for me, and if you both live more than twenty years longer you will actually be making twenty-five pounds a year out of this arrangement. In twenty years you'll be sixty-eight, won't you? Well, there's no reason why you shouldn't live to seventy-two, and if you do you'll make one hundred pounds out of me. So I don't think you can grumble."
"Dear child," sobbed Mrs. Caffyn, "I don't think it's very polite, and it certainly isn't kind, to talk about poor father's age like that. Let's admit we both did wrong and ask him to forgive us."
"I am not going into the question of right and wrong," replied Dorothy, loftily. "It's quite obvious to me that you have a perfect right to do what you like with your own money and that I have a perfect right to avail myself of your kindness. Father's extraordinary behavior has made it equally clear to me that I can't possibly stay on in this house; in any case, the noise the children make in the morning will end by driving me away, and the sooner I go the better."
"I forbid you to speak to your parents like that," said Mr. Caffyn.
Dorothy could not help laughing at his authority, and he played his last card:
"Do you realize that you are not yet of age and that if I choose I can compel you to remain at home?"
"I don't think it would be worth your while," she told him, "for the sake of five hundred pounds, which in that case you'd certainly never see again. I don't want to break with my family completely, but if I find that your prehistoric way of behaving is liable to spoil my career, I sha'n't hesitate to do so."
Dorothy guessed that she had defeated her father; Mrs. Caffyn, too, must have guessed it, for she suddenly gasped:
"I think I must be going to faint."
