I did so; and became at once conscious of an extraordinary throbbing and commotion which was going on inside. The walls of his chest seemed to thrill and quiver as a frail building would do inside when some powerful engine was at work. In the silence of the room I could hear a dull humming and buzzing noise which proceeded from the same source.

“Why,” I cried, “you have an aortic aneurism!”

“That’s what they call it,” he said, placidly. “I went to a Doctor last week about it, and he told me that it is bound to burst before many days passed. It has been getting worse for years. I got it from over-exposure and under-feeding among the Salt Lake Mountains. I’ve done my work now, and I don’t care how soon I go, but I should like to leave some account of the business behind me. I don’t want to be remembered as a common cut-throat.”

The Inspector and the two detectives had a hurried discussion as to the advisability of allowing him to tell his story.

“Do you consider, Doctor, that there is immediate danger?” the former asked.

“Most certainly there is,” I answered.

“In that case it is clearly our duty, in the interests of justice, to take his statement,” said the Inspector. “You are at liberty, sir, to give your account, which I again warn you will be taken down.”

“I’ll sit down, with your leave,” the prisoner said, suiting the action to the word. “This aneurism of mine makes me easily tired, and the tussle we had half an hour ago has not mended matters. I’m on the brink of the grave, and I am not likely to lie to you. Every word I say is the absolute truth, and how you use it is a matter of no consequence to me.”

With these words, Jefferson Hope leaned back in his chair and began the following remarkable statement. He spoke in a calm and methodical manner, as though the events which he narrated were commonplace enough. I can vouch for the accuracy of the subjoined account, for I have had access to Lestrade’s note-book, in which the prisoner’s words were taken down exactly as they were uttered.

“It don’t much matter to you why I hated these men,” he said; “it’s enough that they were guilty of the death of two human beings—a father and a daughter—and that they had, therefore, forfeited their own lives. After the lapse of time that has passed since their crime, it was impossible for me to secure a conviction against them in any court. I knew of their guilt though, and I determined that I should be judge, jury, and executioner all rolled into one. You’d have done the same, if you have any manhood in you, if you had been in my place.
