I would have taken him by the throat; but, springing back, he pointed a revolver at my face.

“Stop that! I’ve had to deal with men like you before, John Ferguson. Attempt to touch me, and I’ll save the hangman his pains.”

I, also, on previous occasions had had to deal with men like him; more dangerous men than he was, free from all the restraints of civilisation, whom use had made handy with a pistol. There was something in the way in which he gripped his weapon which told me that he was not yet acquainted with all its capabilities. I dodged; struck up; the pistol went flying through the air. I took him by the waist; lifted him off his feet; held him tight; and shook him. If you have the trick of it, it is surprising how quickly you can shake the breath clean out of a man’s body, or, if you wish to go so far, by shaking him you can break his back, and make an end. My desires were less extensive. I shook him till I had him quiet; then I lowered him till his face was on a level with mine.

“Now, Dr. Hume, please tell me why I shouldn’t kill you?”

He could but gasp, and that with pain.

“You can—kill me—if you like. You killed him. Killing’s—your line.”

“And what’s your line? Sneaking, like a thief, into a man’s room, and prying into his possessions like some dirty nigger? However, since you are here, we’ll come to an understanding, you and I, before you go.”

I dropped him on to the floor, where he lay like a log, struggling to get back some of his breath. I picked up his revolver. It was a natty little thing, though not of the kind one carries where a gun is one of the chief necessities of existence. There a gun, to be worth anything, should send a bullet through an inch board at the distance of a dozen yards; it was all his would do to send a bullet through the skin of a man. I locked the door, and I waited for him to get his breath again.

“When you are ready, Dr. Hume.”

I sat and watched him. He had followed me with his eyes as I moved about the room; starting as I picked up his pistol. Now he returned me glance for glance. He was getting the better of his breathlessness; and presently raised himself to a sitting posture.
