"No; I want something that I left."

"Ah! thou didst leave something?"

"Yes, and thou didst not find it, maman. Fie, fie, for a clever woman! Well, if thou didst not find it, few could. Wait, now."

He went swiftly up-stairs with Toto, and unlocked the door, leaving the key outside in the lock. He put the writing-materials on a table. In the chimney, just within reach of his farthest touch, he found his pistol. It was not loaded, and he had no powder to recharge it. He laughed as, putting it behind him in his waist-belt, under his cloak, he descended the stair.

"All is right. Cordon, if you please," he cried from the hall. He had not waited outside five minutes when Grégoire appeared, in ordinary dress, without the official feathered hat or the scarf of a functionary. He was now sober enough, but uneasy, and looked about him as if fearing recognition.

"Come," said François. They mounted the ill-smelling stairway to the attic. Neither spoke. Once they were within the room, François said: "Sit down." He took a stool, placing himself between Grégoire and the door. "To business," he said, and slipped out the famous letter from Grégoire to De la Vicomterie. He glanced at it, laughing. "There are three or more heads in this," he said. "Robespierre would pay well for it, or Saint-Just. One might put it up at auction. There would be high bidding."

Grégoire said: "I have paid for it. Give it to me—give it to me!"

"No hurry, commissioner." The thief enjoyed the situation. "Let us talk a little. Let us make things a trifle safer. Have the kindness to write a receipt for one hundred louis d'or accepted by thee as security for the head of one Louis de Ste. Luce, ci-devant marquis."

"Not I!" cried Grégoire, starting up.

"Ah, I think thou wilt"; and, with this, François drew his quite harmless pistol, and cocked it.
