"You couldn't be one of those, if you tried," he replied. "You see, if I may be permitted to say so, nature has endowed you with rather a rare gift so far as your sex is concerned." "Don't be over-diffident," she begged. "I may know it, mayn't I?" "A sense of humour." "When a man tells a woman that she has a sense of humour," Letitia declared, "it is a sure sign that he--" She suddenly realised how intensely observant those steely grey eyes could be. She broke off in her sentence. They still held her, however. "That he what?" "Such a bad habit of mine," she confided frankly. "I so often begin a sentence and have no idea how to finish it. Ada," she went on, addressing Mrs. Honeywell, "has Mr. Thain taught you how to become a millionairess?" "I haven't even tried to learn," that lady replied. "He has promised me a subscription to my Cripples' Guild, though." "What extraordinary bad taste," Letitia remarked, "to cadge from him at dinner time!" "If your father weren't within hearing," Mrs. Honeywell retorted, "I'd let you know what I think of you as a hostess! Why are we all so frightened of your father, Letitia? Look at him now. He is the most picturesque and kindly object you can imagine, yet I find myself always choosing my phrases, and slipping into a sort of pre-Victorian English, when I fancy that he is listening." "I see him more from the family point of view, I suppose," Letitia observed, "and yet, in a way, he is rather a wonderful person. For instance, I have never seen him hurry, I have never seen him angry, in the ordinary sense of the word; in fact he has the most amazing complacency I ever knew. Of course, Aunt Caroline," she went on, turning to the Duchess a few moments later, "if you want to stay with the men, pray do so. If not, you might take into account the fact that I have been trying to catch your eye for the last three minutes." Thain drew up nearer to his host after the women had withdrawn, and found himself next Sir Robert, who talked railways with eloquence and some understanding. Lord Charles was frankly bored, and bestowed his whole attention upon the port. The Marquis discussed a recent land bill with his brother-in-law, but in a very few moments gave the signal to rise. He attached himself at once to David Thain. "You play bridge?" he asked. "Never if I can avoid it," was the frank reply. "Then you and I will entertain one another," his host suggested. The Marquis's idea of entertainment was to install his guest in a comfortable chair in a small den at the back of the house, which he kept for his absolutely private use, and to broach the subject which had led to David's welcome at Grosvenor Square. "Let me ask you," he began, "have you seen anything more of this man Vont?" "Nothing." The Marquis looked ruminatively at the cedar spill with which he had just lit his cigarette.
