"May I ask why?"
"Because your life is in danger. Yes, I see you smile, but I know; I have reason to know."
"No," I replied, "my life is in no danger at all. I gather you are thinking of murder. I happen to be a lawyer, and have studied criminal cases for the last ten years, and I can never remember a murder to have taken place without some grave motive for it. No one has a sufficient motive to kill me. As far as I know, I haven't an enemy in the world, my death would benefit no one, and there is no reason why any would-be murderer would endanger his life by killing me."
The old man looked at me with an amused twinkle in his eye. He seemed to regard me as an interesting specimen of humanity.
"You are talking in the dark, my young friend," he said.
"No," I replied. "I am not talking in the dark, I am talking common sense. If I possessed a secret which was dangerous to any one, if I had it in my power to hurt any one, if I had money which some one desired, if some one hated me very much, if I had done any one any great injury, if I had stolen some young fellow's sweetheart, I could believe there might be truth in your words; but I have done none of these things. I have lived the most commonplace, humdrum life imaginable, and I haven't an enemy in the world. More than that, circumstances have made it unnecessary for any one to kill me. My death will come in a perfectly natural way in a very short time."
"What do you mean by that last sentence?"
"Just as I told you. If you do not believe me, I beg you to refer to Dr. Rhomboid, R-H-O-M-B-O-I-D, of Harley Street, London."
"I see. But you are a cool one!"
"I have no reason to be other than cool."
