looking rather uncomfortable

  The conference was here ended, to Isabel's great relief, by the entrance of Everard, who looked inquiringly at each.   "How are you, old fellow?" he said (for Isabel's proud anger fled at his approach), "what brought you here so unexpectedly?"   "Oh, a little private affair," he replied, looking rather uncomfortable; but there was that in Louis's eye, as he said this, that made Isabel distrust him; something that made her determined to put it out of his power to misrepresent and make mischief. True, he had said how changed he was, and spoken of the reformation his trials had made. Certainly he had been more calm under disappointment than had been his wont. But still she doubted him. She had seen that look before, and knew that it was the same false Louis, not so changed as he imagined. The dark side was only lying dormant; she could read his malicious enjoyment in that cruel smile, and knew its meaning well. Meeting his glance with one of proud defiance and quiet determination, which said, as plainly as words, "I will thwart your fine plans, Mr. Louis," she said:   "You are aware that I was formerly engaged to Dr. Taschereau. His business here to-day was to endeavor to renew that engagement. I need not say how very strange and absurd this appears, as you are acquainted with the circumstances under which the former engagement terminated."   "Yes, that was the 'little private affair,' but I find that you have already won the prize; allow me to congratulate you."   Louis said this in a frank, pleasant manner, appearing to take his own disappointment with so much good nature, at the same time blending a certain degree of sadness in his tone as quite to deceive Everard and win his sympathy. But the thundering black look which he cast at Isabel fully convinced her that she was right.   "You will dine with us, of course," said Everard, cordially.   "I shall do so with pleasure," returned Louis.
