"Sit down," commanded the stern voice of the surgeon.

It was the voice of father to child, of master to slave. The fury left the visitor, who, weak and overcome, fell upon a chair.

Meanwhile, a peculiar light had appeared in the old surgeon's face, the dawn of a strange idea; a gloomy ray, strayed from the fires of the bottomless pit; the baleful light that illumines the way of the enthusiast. The old man remained a moment in profound abstraction, gleams of eager intelligence bursting momentarily through the cloud of sombre meditation that covered his face. Then broke the broad light of a deep, impenetrable determination. There was something sinister in it, suggesting the sacrifice of something held sacred. After a struggle, mind had vanquished conscience.

Taking a piece of paper and a pencil, the surgeon carefully wrote answers to questions which he peremptorily addressed to his visitor, such as his name, age, place of residence, occupation, and the like, and the same inquiries concerning his parents, together with other particular matters.

"Does any one know you came to this house?" he asked.

"No."

"You swear it?"

"Yes."

"But your prolonged absence will cause alarm and lead to search."

"I have provided against that."
