Chauvelin made no retort, pressed his thin lips more tightly together as if to smother any incipient expression of the resentment which he felt. Instinctively his glance sought those of Robespierre, who sat by, still apparently disinterested and impassive, with head bent and arms crossed over his narrow chest.

"Ah, yes!" here interposed Tallien unctuously. "Citizen Chauvelin has had one or two opportunities of measuring his prowess against that of the mysterious Englishman; but we are told that, despite his great talents, he has met with no success in that direction."

"Do not tease our modest friend Chauvelin, I pray you, citizen," Theresia broke in gaily. "The Scarlet Pimpernel—that is the name of the mysterious Englishman, is it not?—is far more elusive and a thousand times more resourceful and daring than any mere man can possibly conceive. 'Tis woman's wits that will bring him to his knees one day. You may take my word for that!"

"Your wits, citoyenne?"

Robespierre had spoken. It was the first time, since the discussion had turned on the present subject, that he had opened his lips. All eyes were at once reverentially turned to him. His own, cold and sarcastic, were fixed upon Theresia Cabarrus.

She returned his glance with provoking coolness, shrugged her splendid shoulders, and retorted airily:

"Oh, you want a woman with some talent as a sleuthhound—a female counterpart of citizen Chauvelin. I have no genius in that direction."

"Why not?" Robespierre went on drily. "You, fair citoyenne, would be well qualified to deal with the Scarlet Pimpernel, seeing that your adorer, Bertrand Moncrif, appears to be a protégé of the mysterious League."

At this taunt, uttered by the dictator with deliberate emphasis, like one who knows what he is talking about, Tallien gave a gasp and his sallow cheeks became the colour of lead. But Theresia placed her cool, reassuring hand upon his.

"Bertrand Moncrif," she said serenely, "is no adorer of mine. He foreswore his allegiance to me on the day that I plighted my troth to citizen Tallien."
