“So for many months the laboratory door remained locked. Then there came a chill autumn evening when the man of science opened it again, and closed it behind him.
“He lighted his lamp, and gathered his instruments and books around him, and sat down before them in his high-backed chair. And the old terror returned to him.
“But this time he meant to conquer himself. His nerves were stronger now, and his brain clearer; he would fight his unreasoning fear. He crossed to the door and locked himself in, and flung the key to the other end of the room, where it fell among jars and bottles with an echoing clatter.
“Later on, his old housekeeper, going her final round, tapped at his door and wished him good-night, as was her custom. She received no response, at first, and, growing nervous, tapped louder and called again; and at length an answering ‘good-night’ came back to her.
“She thought little about it at the time, but afterwards she remembered that the voice that had replied to her had been strangely grating and mechanical. Trying to describe it, she likened it to such a voice as she would imagine coming from a statue.
“Next morning his door remained still locked. It was no unusual thing for him to work all night and far into the next day, so no one thought to be surprised. When, however, evening came, and yet he did not appear, his servants gathered outside the room and whispered, remembering what had happened once before.
“They listened, but could hear no sound. They shook the door and called to him, then beat with their fists upon the wooden panels. But still no sound came from the room.
“Becoming alarmed, they decided to burst open the door, and, after many blows, it gave way, and they crowded in.
“He sat bolt upright in his high-backed chair. They thought at first he had died in his sleep. But when they drew nearer and the light fell upon him, they saw the livid marks of bony fingers round his throat; and in his eyes there was a terror such as is not often seen in human eyes.”
