"Some one else, maybe," suggested Burt.
"The man who put you on your back at the station," said Ezra.
"Ha! I'll pay him for that," the navvy growled viciously.
"A human life, Mr. Burt," continued Girdlestone, "is a sacred thing, but a human life, when weighed against the existence of a great firm from which hundreds derive their means of livelihood, is a small consideration indeed. When the fate of Miss Harston is put against the fate of the great commercial house of Girdlestone, it is evident which must go to the wall."
Burt nodded, and poured some more Hollands from the square bottle.
"Having seen," Girdlestone continued, "that this sad necessity might arise, I had made every arrangement some time before. This building is, as you may have observed in your drive, situated in a lonely and secluded part of the country. It is walled round too in such a manner that any one residing here is practically a prisoner. I removed the lady so suddenly that no one can possibly know where she has gone to, and I have spread such reports as to her condition that no one down here would be surprised to hear of her decease."
"But there is bound to be an inquiry. How about a medical certificate?" asked Ezra.
"I shall insist upon a coroner's inquest," his father answered.
"An inquest! Are you mad?"
"When you have heard me I think that you will come to just the opposite conclusion. I think that I have hit upon a scheme which is really neat--neat in its simplicity." He rubbed his hands together, and showed his long yellow fangs in his enjoyment of his own astuteness.
Burt and Ezra leaned forward to listen, while the old man sank his voice to a whisper.
"They think that she is insane," he said.
"Yes."
"There's a small door in the boundary wall which leads out to the railway line."
"Well, what of that?"
"Suppose that door to be left open, would it be an impossible thing for a crazy woman to slip out through it, and to be run over by the ten o'clock express?"
"If she would only get in the way of it."
"You don't quite catch my idea yet. Suppose that the express ran over the dead body of a woman, would there be anything to prove afterwards that she was dead, and not alive at the time of the accident? Do you think that it would ever occur to any one's mind that the express ran over a dead body?"
"I see your meaning," said his son thoughtfully. "You would settle her, and then put her there."
