“For instance, Monsieur Chauvelin?”

“There is the destruction of his honour,” he replied slowly.

A long, bitter laugh, almost hysterical in its loud outburst, broke from the very depths of Marguerite's convulsed heart.

“The destruction of his honour!... ha! ha! ha! ha!... of a truth, Monsieur Chauvelin, your inventive powers have led you beyond the bounds of dreamland!... Ha! ha! ha! ha!... It is in the land of madness that you are wandering, sir, when you talk in one breath of Sir Percy Blakeney and the possible destruction of his honour!”

But he remained apparently quite unruffled, and when her laughter had somewhat subsided, he said placidly:

“Perhaps!...”

Then he rose from his chair, and once more approached her. This time she did not shrink from him. The suggestion which he had made just now, this talk of attacking her husband's honour rather than his life, seemed so wild and preposterous—the conception truly of a mind unhinged—that she looked upon it as a sign of extreme weakness on his part, almost as an acknowledgement of impotence.

But she watched him as he moved round the table more in curiosity now than in fright. He puzzled her, and she still had a feeling at the back of her mind that there must be something more definite and more evil lurking at the back of that tortuous brain.

“Will your ladyship allow me to conduct you to yonder window?” he said, “the air is cool, and what I have to say can best be done in sight of yonder sleeping city.”

His tone was one of perfect courtesy, even of respectful deference through which not the slightest trace of sarcasm could be discerned, and she, still actuated by curiosity and interest, not in any way by fear, quietly rose to obey him. Though she ignored the hand which he was holding out towards her, she followed him readily enough as he walked up to the window.
