"I know I don't," said Tony cheerfully. "That's what's so charming about it." He paused. "Suppose we have a week's trial at all events?" he suggested. "If it turns out a failure it will be just as easy for you to disappear then. You know both Guy and I improve on acquaintance--really. You mustn't judge us by what we are like at breakfast. We get much more bright and pleasant as the day wears on." In spite of herself Isabel laughed. "It isn't that I don't want to stay," she said. "I--I like you both very much." She hesitated and looked nervously round the room as if seeking for inspiration. "It's what might happen," she added. "I can't explain, but I might be the cause of getting you into trouble or--or even danger." "That's all right," said Tony. "I like danger, and Guy simply adores trouble. He takes it with everything." Isabel made a faint gesture of helplessness. "Oh," she said. "I can't go on arguing. You are so obstinate. But I have warned you, haven't I?" Tony nodded. "If you like to call it a warning," he said. "I look on it more as a promise. If you knew how dull Hampstead was you would understand our morbid thirst for a little unhealthy excitement." "I don't think I should find Hampstead dull," remarked Isabel a shade wistfully. "It seems to me just beautifully peaceful. I think I should like to live here for ever, and do exactly what I want to, and not be bothered about anything." "But that's precisely what I am suggesting," observed Tony. Isabel smiled again. She seemed to be recovering her spirits. "I should have to get some clothes first," she said. "I couldn't live here for ever on the contents of one small dressing-bag." "It sounds inadequate," agreed Tony, "but I think that's a difficulty we might get over. I was just going to propose that you should take the car and Mrs. Spalding this afternoon, and go and do some shopping." Isabel's eyes sparkled. "How lovely!" she exclaimed. Then a sudden cloud came over her face. "But I forgot," she added, "I haven't any money--not until you have sold the brooch for me." "That doesn't matter," said Tony. "If you will let me, I will advance you fifty pounds, and you can pay me to-morrow when we settle up." Isabel took a deep breath. "Oh, you are kind," she said. Then for a moment she paused, her forehead knitted as though some unpleasant thought had suddenly come into her mind. "Anything wrong?" inquired Tony. She looked round again with the same half-nervous, half-hunted expression he had seen before. "I was thinking," she faltered. "Those two men. I wonder if there is any chance that I might meet them again. I--I know it's silly to be frightened, but somehow or other--" She broke off as if hardly knowing how to finish the sentence. Tony leaned across the table and took her hand in his.
