"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."
"Of course. What could be more delightfully simple. Friend Burt here does his work; we carry her through the garden gate, and lay her on the darkest part of the rails. Then we miss her at the house. There is an alarm and a search. The gate is found open. We naturally go through with lanterns, and find her on the line. I don't think we need fear the coroner, or any one else then?"
"He's a sharp 'un, is the guv'nor," cried Burt, slapping his thigh enthusiastically. "It's the downiest lay I have heard this many a day."
"I believe you are the devil incarnate," said Ezra, looking at his father with a mixture of horror and of admiration. "But how about Jorrocks and Stevens and Rebecca? Would you trust them?"
"Certainly not!" Girdlestone answered. "It is not necessary. Mr. Burt can do his part of the business out of doors. We can entice her out upon some excuse. There is no reason why any one should have a suspicion of the truth."
"But they know that she is not mad."
