"You know quite well what right I had, citizen Lebel," replied Chauvelin with perfect composure. "The right conferred upon me by the Committee of Public Safety, of whom I am still an unworthy member. They sent me down here to lend you a hand in an investigation which is of grave importance to them."

"I know that!" retorted Lebel sulkily. "But why have invented the story of the papers?"

"It is no invention, citizen," rejoined Chauvelin with slow emphasis. "The papers do exist. They are actually in the possession of the Montorgueils, father and son. To capture the two aristos would be not only a blunder, but criminal folly, unless we can lay hands on the papers at the same time."

"But what in Satan's name are those papers?" ejaculated Lebel with a fierce oath."

"Think, citizen Lebel! Think!" was Chauvelin's cool rejoinder. "Methinks you might arrive at a pretty shrewd guess." Then, as the other's bluster and bounce suddenly collapsed under his colleague's calm, accusing gaze, the latter continued with impressive deliberation:

"The papers which the two aristos have in their possession, citizen, are receipts for money, for bribes paid to various members of the Committee of Public Safety by royalist agents for the overthrow of our glorious Republic. You know all about them, do you not?"

While Chauvelin spoke, a look of furtive terror had crept into Lebel's eyes; his cheeks became the colour of lead. But even so, he tried to keep up an air of incredulity and of amazement.

"I?" he exclaimed. "What do you mean, citizen Chauvelin? What should I know about it?"

"Some of those receipts are signed with your name, citizen Lebel," retorted Chauvelin forcefully. "Bah!" he added, and a tone of savage contempt crept into his even, calm voice now. "Hériot, Foucquier, Ducros and the whole gang of you are in it up to the neck: trafficking with our enemies, trading with England, taking bribes from every quarter for working against the safety of the Republic. Ah! if I had my way, I would let the hatred of those aristos take its course. I would let the Montorgueils and the whole pack of Royalist agents publish those infamous proofs of your treachery and of your baseness to the entire world, and send the whole lot of you to the guillotine!"

He had spoken with so much concentrated fury, and the hatred and contempt expressed in his pale eyes were so fierce than an involuntary ice-cold shiver ran down the length of Lebel's spine. But, even so, he would not give in; he tried to sneer and to keep up something of his former surly defiance.

"Bah!" he exclaimed, and with a lowering glance gave hatred for hatred, and contempt for contempt. "What can you do? An I am not mistaken, there is no more discredited man in France to-day than the unsuccessful tracker of the Scarlet Pimpernel."

The taunt went home. It was Chauvelin's turn now to lose countenance, to pale to the lips. The glow of virtuous indignation died out of his eyes, his look became furtive and shamed.

"You are right, citizen Lebel," he said calmly after a while. "Recriminations between us are out of place. I am a discredited man, as you say. Perhaps it would have been better if the Committee had sent me long ago to expiate my failures on the guillotine. I should at least not have suffered, as I am suffering now, daily, hourly humiliation at the thought of the triumph of an enemy, whom I hate with a passion which consumes my very soul. But do not let us speak of me," he went on quietly. "There are graver affairs at stake just now than mine own."

Lebel said nothing more for the moment. Perhaps he was satisfied at the success of his taunt, even though the terror within his craven soul still caused the cold shiver to course up and down his spine. Chauvelin had once more turned to the window; his gaze was fixed upon the distance far away. The window gave on the North. That way, in a straight line, lay Calais, Boulogne, England - where he had been made to suffer such bitter humiliation at the hands of his elusive enemy. And immediately before him was Paris, where the very walls seemed to echo that mocking laugh of the daring Englishman which would haunt him even to his grave.

Lebel, unnerved by his colleague's silence, broke in a gruffly at last:

"Well, then, citizen," he said, with a feeble attempt at another sneer, "if you are not thinking of sending us all to the guillotine just yet, perhaps you will be good enough to explain just how the matter stands?"

"Fairly simply, alas!" replied Chauvelin dryly. "The two Montorgueils, father and son, under assumed names, were the Royalist agents who succeeded in suborning men such as you, citizen - the whole gang of you. We have tracked them down to this district, have confiscated their lands and ransacked the old château for valuables and so on. Two days later, the first of a series of pestilential anonymous letters reached the Committee of Public Safety, threatening the publication of a whole series of compromising documents if the Marquis and the Vicomte de Montorgueil were in any way molested, and if all the Montorgueil property is not immediately restored."

"I suppose it is quite certain that those receipts and documents do exist?" suggested Lebel.

"Perfectly certain. One of the receipts, signed by Hériot, was sent as a specimen."

"My God!" ejaculated Lebel, and wiped the cold sweat from his brow.

"Yes, you'll all want help from somewhere," retorted Chauvelin coolly. "From above or from below, what? if the people get to know what miscreants you are. I do believe," he added, with a vicious snap of his thin lips, "that they would cheat the guillotine of you and, in the end, drag you out of the tumbrils and tear you to pieces limb from limb!"

Once more that look of furtive terror crept into the commissary's bloodshot eyes.

"Thank the Lord," he muttered, "that we were able to get hold of the wench Clamette!"

"At my suggestion," retorted Chauvelin curtly. "I always believe in threatening the weak if you want to coerce the strong. The Montorgueils cannot resist the wench's appeal. Even if they do at first, we can apply the screw by clapping one of the young ones into gaol. Within a week we shall have those papers, citizen Lebel; and if, in the meanwhile, no one commits a further blunder, we can close the trap on the Montorgueils without further trouble."

Lebel said nothing more, and after awhile Chauvelin went back to the desk, picked up the letter which poor Lucile had written and watered with her tears, folded it deliberately and slipped it into the inner pocket of his coat.

"What are you going to do?" queried Lebel anxiously.

"Drop this letter into the hollow tree by the side of the stable gate at Montorgueil," replied Chauvelin simply.

"What?" exclaimed the other. "Yourself?"

"Why, of course! Think you I would entrust such an errand to another living soul?"

Chapter III:

A couple of hours later, when the two children had had their dinner and had settled down to play in the garden, and father been cosily tucked up for his afternoon sleep, Lucile called her brother Etienne to her. The boy had not spoken to her since that terrible time spent in the presence of those two awful men. He had eaten no dinner, only sat glowering, staring straight out before him, from time to time, throwing a look of burning reproach upon his sister. now, when she called to him, he tried to run away, was halfway up the stairs before she could seize hold of him.
