I walked farther into the room, and stood opposite to him on the rug before the fireplace. He drew a chair in front of the door, and sat down on it, with his left arm resting on the table. The cage with the white mice was close to him, and the little creatures scampered out of their sleeping-place as his heavy arm shook the table, and peered at him through the gaps in the smartly painted wires.

"You have said enough," he replied, with a sudden composure so unnatural and so ghastly that it tried my nerve
