The negro started back, rolling his eyes like a maniac, but he spoke no word. He was shivering with fear. I smiled and returned the weapon to my pocket. Thereupon I gripped his arm and muttered in his ear: "Proceed!"

Uttering a sort of groan, he set off slowly for the Rue Saint Denis. "Quicker!" I commanded. He increased his pace. We turned the corner, and a smart walk brought us quickly to the Rue D'Enghien. Turning into that street the negro stopped presently before the door of a large three-storied house, whose every window was closely shuttered.

"We have arrived, monsieur," he muttered in a hollow voice.

"You have a latch-key, perhaps?" I asked.

"Yes."

I looked steadily at the house for a moment or two, then curtly ordered my companion to proceed, still, however, retaining a firm hold of his arm. Five minutes later we came to the Faubourg Poissonnière. Hailing a fiacre, I invited Jussieu to enter, and quickly took a seat beside him. "The Hotel de Louvre!" I shouted to the driver, and we were off.

The negro was so still and docile that I began to suspect him of meditating some plan of escape. Producing my pistol, I thrust the muzzle into his side and cocked it with a loud click. "Death is very near to you, Jussieu!" I said.

"For God's sake, monsieur!" he groaned.

"Sit very still, Jussieu. It has a hair trigger, and my hand is trembling. I am remembering that it was you who pierced my fingers with needles and seared my foot with branding irons!"

"Mercy, mercy! Forgive!" he wailed.
