"Good," replied Barbesieur. "Now, look at me full in the eyes. Look, I tell you!" repeated he, as Strozzi's face began to relapse into imbecility. "I have found the poison."
Strozzi uttered a triumphant yell, but Barbesieur silenced him. "Pay attention while I tell you how I became possessed of it. I was by, when La Voisin was put to the torture in La Chambre ardente, and I heard her confession. I was deputed to search for her papers; and before I delivered them up you may be sure that I examined them, to see what I could make out of them for my own profit. I found various receipts for love-potions, as well as for the renowned poudre de succession of the Countess Soissons; but of that anon. Do you mark me, Strozzi?"
"Oh, sir," cried Strozzi, trembling in every limb, "speak—speak quickly, or I shall die of suspense!"
Barbesieur then, emphasizing each word, replied: "I found a parchment on which were inscribed these words: 'Receipt for procuring death by inhalation. Queen Katherina de Medicis.'"
"That is it, that is it," howled Strozzi, and in his ecstasy he flung his arms around Barbesieur's great body. But suddenly his countenance became expressive of distrust, and his eye had a deadly glitter, like that of a snake.
"But will you give it to me? Where is it? I warn you, do not trifle with me, for you never shall leave this laboratory until I have it!" Meanwhile he made a furtive movement toward his breast.
But Barbesieur had seen the gesture, and with his powerful grasp he clutched Strozzi's hand, and withdrew it armed with a poniard of fine, glistening steel. Flinging it with such force against the wall that it buried itself in the masonry, Barbesieur gazed for a moment at the poor fool whose teeth were chattering with fear; then leading him to a seat—
"Come," said he, "let us talk like men. We are neither enemies nor rivals; we are brothers, having one and the same interest at stake."
"Yes, sir," murmured Strozzi, obsequiously.
"Well, then, look at me. Did you ever see me before?"
