"That is an original way to look at it. Perhaps you are right. Put what do you suppose he will do, in the way of taking extra precautions?"

"I think he will try to put me out of the way," said the detective, smiling.

"Do you mean that he will attempt to assassinate you?"

"Exactly that."

"And that you purposely invite such a thing?"

"Certainly."

"But, Mr. Carter, isn't that rather foolhardy?"

"No; I don't think so. My object is to get him to show his hand. If his system is as perfect as we think it is, he knows already that I am here, and that I am holding an interview with you. He fears me, as he fears nobody else. He has had a taste of what I can do to him, I hope this does not sound like egotism. I don't mean it so."

"Not at all."

"And therefore, since I am here again, he will guess at once that you have suspected his presence and have sent for me, and he will figure it out that the only way to be safe is to get rid of me."
