"You are an heiress," he said, "for, whatever you did, I should never change my mind. Oh, I know you will do nothing of which I should disapprove, but there is the fact. If you marry Frank you would still get your two hundred thousand, though I should bitterly regret your marriage. No, my girl," he said more kindly than was his wont, "I only ask you this--that whatever else you do, you will not make your choice until the next fortnight has expired." With a jerk of his head, John Minute summoned a waiter and paid his bill. No more was said until he handed her into her cab in the courtyard. "I shall be in town next week," he said.
