Vol. II, Book III, Chap. X: “He Who Seeks to Better Himself May Render His Situation Worse” Victor Hugo

Madame Thenardier had allowed her husband to have his own way, as was her wont. She had expected great results. When the man and Cosette had taken their departure, Thenardier allowed a full quarter of an hour to elapse; then he took her aside and showed her the fifteen hundred francs.
"Is that all?" said she.
It was the first time since they had set up housekeeping that she had dared to criticise one of the master's acts.
The blow told.
"You are right, in sooth," said he; "I am a fool. Give me my hat."
He folded up the three bank-bills, thrust them into his pocket, and ran out in all haste; but he made a mistake and turned to the right first. Some neighbors, of whom he made inquiries, put him on the track again; the Lark and the man had been seen going in the direction of Livry. He followed these hints, walking with great strides, and talking to himself the while:—
"That man is evidently a million dressed in yellow, and I am an animal. First he gave twenty sous, then five francs, then fifty francs, then fifteen hundred francs, all with equal readiness. He would have given fifteen thousand francs. But I shall overtake him."
And then, that bundle of clothes prepared beforehand for the child; all that was singular; many mysteries lay concealed under it. One does not let mysteries out of one's hand when one has once grasped them. The secrets of the wealthy are sponges of gold; one must know how to subject them to pressure. All these thoughts whirled through his brain. "I am an animal," said he.
When one leaves Montfermeil and reaches the turn which the road takes that runs to Livry, it can be seen stretching out before one to a great distance across the plateau. On arriving there, he calculated that he ought to be able to see the old man and the child. He looked as far as his vision reached, and saw nothing. He made fresh inquiries, but he had wasted time. Some passers-by informed him that the man and child of whom he was in search had gone towards the forest in the direction of Gagny. He hastened in that direction.
They were far in advance of him; but a child walks slowly, and he walked fast; and then, he was well acquainted with the country.
All at once he paused and dealt himself a blow on his forehead like a man who has forgotten some essential point and who is ready to retrace his steps.
"I ought to have taken my gun," said he to himself.
Thenardier was one of those double natures which sometimes pass through our midst without our being aware of the fact, and who disappear without our finding them out, because destiny has only exhibited one side of them. It is the fate of many men to live thus half submerged. In a calm and even situation, Thenardier possessed all that is required to make—we will not say to be—what people have agreed to call an honest trader, a good bourgeois. At the same time certain circumstances being given, certain shocks arriving to bring his under-nature to the surface, he had all the requisites for a blackguard. He was a shopkeeper in whom there was some taint of the monster. Satan must have occasionally crouched down in some corner of the hovel in which Thenardier dwelt, and have fallen a-dreaming in the presence of this hideous masterpiece.
After a momentary hesitation:—
"Bah!" he thought; "they will have time to make their escape."
And he pursued his road, walking rapidly straight ahead, and with almost an air of certainty, with the sagacity of a fox scenting a covey of partridges.
In truth, when he had passed the ponds and had traversed in an oblique direction the large clearing which lies on the right of the Avenue de Bellevue, and reached that turf alley which nearly makes the circuit of the hill, and covers the arch of the ancient aqueduct of the Abbéy of Chelles, he caught sight, over the top of the brushwood, of the hat on which he had already erected so many conjectures; it was that man's hat. The brushwood was not high. Thenardier recognized the fact that the man and Cosette were sitting there. The child could not be seen on account of her small size, but the head of her doll was visible.
Thenardier was not mistaken. The man was sitting there, and letting Cosette get somewhat rested. The inn-keeper walked round the brushwood and presented himself abruptly to the eyes of those whom he was in search of.
"Pardon, excuse me, sir," he said, quite breathless, "but here are your fifteen hundred francs."
So saying, he handed the stranger the three bank-bills.
The man raised his eyes.
"What is the meaning of this?"
Thenardier replied respectfully:—
"It means, sir, that I shall take back Cosette."
Cosette shuddered, and pressed close to the old man.
He replied, gazing to the very bottom of Thenardier's eyes the while, and enunciating every syllable distinctly:—
"You are go-ing to take back Co-sette?"
"Yes, sir, I am. I will tell you; I have considered the matter. In fact, I have not the right to give her to you. I am an honest man, you see; this child does not belong to me; she belongs to her mother. It was her mother who confided her to me; I can only resign her to her mother. You will say to me, 'But her mother is dead.' Good; in that case I can only give the child up to the person who shall bring me a writing, signed by her mother, to the effect that I am to hand the child over to the person therein mentioned; that is clear."
The man, without making any reply, fumbled in his pocket, and Thenardier beheld the pocket-book of bank-bills make its appearance once more.
The tavern-keeper shivered with joy.
"Good!" thought he; "let us hold firm; he is going to bribe me!"
Before opening the pocket-book, the traveller cast a glance about him: the spot was absolutely deserted; there was not a soul either in the woods or in the valley. The man opened his pocket-book once more and drew from it, not the handful of bills which Thenardier expected, but a simple little paper, which he unfolded and presented fully open to the inn-keeper, saying:—
"You are right; read!"
Thenardier took the paper and read:—
"M. SUR M., March 25, 1823.
