"Oh, Harry's been in England," she said quickly; and then, with a flashing thought, came to her the one scene Harry had mentioned in his English experience. Was it at a ball? The question came to her lips, but she checked it there. She remembered how Harry had stopped her the night before with a nod, with a look, from mentioning that very thing. Still she hesitated--for the temptation was strong. But no; it was only loyal to Harry to speak to him first. "So you're not going to tell me?" Kerr remarked, and she came back to a sudden consciousness of how her face must have reflected her thought. "No--not this time!" she said, smiling, though somewhat flushed. He knitted his brows at her. They had reached the arched gate, and the car that would carry her home was approaching. "Ah, then, I am afraid it will be never," he said. Was it possible this was their last meeting? Did he mean he was going away? The questions formed in her mind, but there was no time for words. He had stopped the car with a flick of his agile cane, and handed her in as if he had handed her into a carriage; and not a word as to whether they would see each other again, though she hoped and hesitated to the last moment. Her hand was in his for the fraction of a minute. Then the car was widening the distance between them, and she was no longer looking into his face, which had seemed at their last moment both merry and wistful, but back at his diminishing figure, showing black against the pale Presidio hills. V ON GUARD He had so disturbed her, his presence had so obliterated other presences and annihilated time, that it took an encounter with Clara to remind her of her arrangement for the evening. The dance? No, she had given that up. She had promised Harry to be at home. Clara wanted to know rather austerely what she intended to do about the dinner. This was dreadful! Flora had forgotten it completely. Nothing to be done but go, and leave a message for Harry--apology, and assurance that she would be home early. She wondered if she were losing her memory. She appeared to be changing altogether, for the dinner--a merry one--bored her. What she wanted was to get away from it as soon as possible for that interesting evening. When she had made the appointment with Harry she had been excited by the thought that he might tell her whether he had learned anything from the major that morning in the matter of the ring. But now she was more engrossed with the idea of asking about Kerr--whether Harry had really met him--if so, where; and, finally, why did not Harry want her to mention that Embassy ball?
