This anterior existence could no longer be denied, although he knew nothing about it. In the uncertainty of his mind he could not associate the date 1721 with his visit to the Conciergerie.
However, he came to this final conclusion. In 1721 he had been confined in the Conciergerie Prison, probably as a prisoner of state. He could not admit for a second that he, Théophraste Longuet, had been shut up, even under Louis XV, as a common criminal. In a solemn moment, perhaps before being put to torture, he had drawn up this document and hidden the paper between the stones in the dungeon, and passing by there two centuries later, had found it again. This was simple enough and not the result of any supernatural inspiration. The facts themselves were enough.
Certain words of the document were in themselves quite natural and of the most momentous importance. These were “Treasure... treachery of the first of April.”
It was with these words that he hoped to discover his identity. First, he had been rich and powerful. The words about the treasure showed conclusively that the man had been rich and that he had buried his treasure. He had been powerful and had been betrayed. Théophraste had in his mind that the treason had been a memorable treason, perhaps historic-the treachery of the first of April.
Yes, all the oddities and all the mysteries of the document left at least a glimpse of something certain: that he had been a great personage, that he had buried his treasures; and that after having buried them mysteriously, more mysteriously still revealed their existence, at the price of much cunning; perhaps at the price of his own blood. Without doubt those tinted words had been written with blood.
Later he proposed to ask a distinguished chemist to examine it. The treasures belonged to him, and if necessary he would use this document to establish his right to them.
Théophraste was not rich. He had retired from business with a modest little income. He had a comfortable little house with a garden and bowling alley. However, this was little, with the somewhat extravagant tastes of Marceline, and so the treasure would be most acceptable. He therefore applied himself diligently to the research.
It must be said, though, to his credit, that he was much more puzzled by the mystery of his personality than by the mystery of the treasure, and that he resolved to temporarily suspend his research until the time when he could at least give a name to this personage that he had been-Théophraste Longuet in 1721. That discovery which interested him most came to be in his mind the key of all the others.
That which astonished him most was the sudden development of what he called his “historical instinct,” the instinct which had been deficient in him all his life, but which had been revealed to him with the suddenness and force of a clap of thunder in the depths of the Conciergerie. In one moment, the Other, as he used to say in conversing of this great 18th-century personage, had possessed him. It was the Other who had found the document; it was the Other who had cried out in the Conciergerie; it was the Other who had called to Simon l’Anvergust, and since the Other had disappeared, Théophraste did not know what had become of him. He sought him in vain; he examined himself; he searched his very soul.
Before this adventure Théophraste had no curiosity about the beginning or ending of things, he had not wasted time in wondering over philosophical mysteries; in his vanity he had always shrugged his shoulders at such things. However, now things were different; here was a quiet citizen, with little scientific knowledge, who had to prove that a manufacturer of India rubber in the year 1899 had been shut up in a dungeon after having buried treasures in 1721. But the revelation of this extraordinary fact had come to him spontaneously and remained so fixed in his mind that he resolved to probe the matter to the bottom.
