Monica hinted an amused surprise.

“You see,” he went on, “I expected nothing, and happy for me that it was so. Miss Nunn was in her severest mood; I think she didn’t smile once through the evening. I will confess to you I wrote her a letter whilst I was abroad, and it offended her, I suppose.”

“I don’t think you can always judge of her thoughts by her face.”

“Perhaps not. But I have studied her face so often and so closely. For all that, she is more a mystery to me than any woman I have ever known. That, of course, is partly the reason of her power over me. I feel that if ever—if ever she should disclose herself to me, it would be the strangest revelation. Every woman wears a mask, except to one man; but Rhoda’s—Miss Nunn’s—is, I fancy, a far completer disguise than I ever tried to pierce.”

Monica had a sense of something perilous in this conversation. It arose from a secret trouble in her own heart, which she might, involuntarily, be led to betray. She had never talked thus confidentially with any man; not, in truth, with her husband. There was no fear whatever of her conceiving an undue interest in Barfoot; certain reasons assured her of that; but talk that was at all sentimental gravely threatened her peace—what little remained to her. It would have been better to discourage this man’s confidences; yet they flattered her so pleasantly, and afforded such a fruitful subject for speculation, that she could not obey the prompting of prudence.

“Do you mean,” she said, “that Miss Nunn seems to disguise her feelings?”

“It is supposed to be wrong—isn’t it?—for a man to ask one woman her opinion of another.”

“I can’t be treacherous if I wished,” Monica replied. “I don’t feel that I understand her.”

Barfoot wondered how much intelligence he might attribute to Mrs. Widdowson. Obviously her level was much below that of Rhoda. Yet she seemed to possess delicate sensibilities, and a refinement of thought not often met with in women of her position. Seriously desiring her aid, he looked at her with a grave smile, and asked,—

“Do you believe her capable of falling in love?”
