"But why should it?" asked Duncan, in unfeigned astonishment. "Why should ordinary social courtesy on my part mean more than the same thing means in the case of any other young man?"

"I don't know that I can tell you," she answered. "At least, I don't know that I can make you understand."

"I sincerely wish you would try. I certainly do not want to——" He hesitated, and did not complete the sentence.

"Oh, I know all that. I know what you mean, because it is what I mean. I tell you that if you pay more than just a little, and a very casual, attention to any girl, the girl, and, worse still, all her elderly female relatives, are likely to misconstrue your motives. You are in serious danger of breaking some tender hearts, and winning for yourself the reputation of being that most detestable thing—a male flirt."

"But really, Mrs. Hallam," interrupted the perplexed young man, "I don't understand——"

"Of course you don't, and of course I'm glad you don't. You'd be a detestably conceited popinjay if you did. But I do, and in a strictly limited way I'm going to explain it to you for your own good, and as a warning. I can't explain it fully without treason to my own sex. But I'll tell you this much: you have a singularly pleasing, soothing, caressing, and most winning manner with women—all women. You are respectful—no, that isn't the word. You are courteously gentle and deferential, and solicitous to give pleasure. Anyhow, you please women. Then, again, you have made yourself the most conspicuous young man in Cairo, and everybody counts upon your success as certain. There, I'm not going to explain further; I only warn you."

"But, Mrs. Hallam, I have not called more than twice upon any one girl, and——"

"Well, don't. That's all I've got to say."

Duncan went away puzzled. He had intended to be very shrewd and circumspect in this matter. He had intended, by calling once or twice upon each of several young women, to deprive the calls he intended to make upon Barbara of any look of significance, and now, before he had even begun to cultivate acquaintance with Barbara, he found his small preparatory callings the subject of curiosity and gossip.

He was resolved not to be balked of his purpose, however. He saw no reason to permit that. He would go that very evening to see Barbara, and he would repeat the visit from time to time, until a fuller acquaintance with the girl should cure him of his fascination. Acquaintance must do that, he was persuaded.
