The people were leaving their seats at the principal table. M. Beautrelet went and took the paper and handed it to his son. “Read it out! Read it out!” they cried, louder. And others said: “Listen! He’s going to read it! Listen!” Beautrelet stood facing his audience, looked in the evening paper which his father had given him for the article that was causing all this uproar and, suddenly, his eyes encountering a heading underlined in blue pencil, he raised his hand to call for silence and began in a loud voice to read a letter addressed to the editor by M. Massiban, of the Academy of Inscriptions and Belles-Lettres. His voice broke and fell, little by little, as he read those stupefying revelations, which reduced all his efforts to nothing, upset his notions concerning the Hollow Needle and proved the vanity of his struggle with Arsène Lupin: SIR: On the 17th of March, 1679, there appeared a little book with the following title: _The Mystery of the Hollow Needle. The Whole Truth now first exhibited. One hundred copies printed by myself for the instruction of the Court._ At nine o’clock on the morning of that day, the author, a very young man, well-dressed, whose name has remained unknown, began to leave his book on the principal persons at court. At ten o’clock, when he had fulfilled four of these errands, he was arrested by a captain in the guards, who took him to the king’s closet and forthwith set off in search of the four copies distributed. When the hundred copies were got together, counted, carefully looked through and verified, the king himself threw them into the fire and burnt them, all but one, which he kept for his own purposes. Then he ordered the captain of the guards to take the author of the book to M. de Saint-Mars, who confined his prisoner first at Pignerol and then in the fortress of the Ile Sainte-Marguerite. This man was obviously no other than the famous Man with the Iron Mask. The truth would never have been known, or at least a part of the truth, if the captain in the guards had not been present at the interview and if, when the king’s back was turned, he had not been tempted to withdraw another of the copies from the chimney, before the fire got to it. Six months later, the captain was found dead on the highroad between Gaillon and Mantes. His murderers had stripped him of all his apparel, forgetting, however, in his right boot a jewel which was discovered there afterward, a diamond of the first water and of considerable value.
