“Have you swallowed a bullet, Mr. Glenarm?” he called.

I could hear his feet scraping on the cement floor; he was moving away from me, doubtless intending to fire when he reached the area window and escape before I could reach him. I crept warily after him, ready to fire on the instant, but not wishing to throw away my last cartridge. That I resolved to keep for close quarters at the window.

He was now very near the end of the corridor; I heard his feet strike some boards that I remembered lay on the floor there, and I was nerved for a shot and a hand-to-hand struggle, if it came to that.

I was sure that he sought the window; I heard his hands on the wall as he felt for it. Then a breath of cold air swept the passage, and I knew he must be drawing himself up to the opening. I fired and dropped to the floor. With the roar of the explosion I heard him yell, but the expected return shot did not follow.

The pounding of my heart seemed to mark the passing of hours. I feared that my foe was playing some trick, creeping toward me, perhaps, to fire at close range, or to grapple with me in the dark. The cold air still whistled into the corridor, and I began to feel the chill of it. Being fired upon is disagreeable enough, but waiting in the dark for the shot is worse.

I rose and walked toward the end of the passage.

Then his revolver flashed and roared directly ahead, the flame of it so near that it blinded me. I fell forward confused and stunned, but shook myself together in a moment and got upon my feet. The draft of air no longer blew into the passage. Morgan had taken himself off through the window and closed it after him. I made sure of this by going to the window and feeling of it with my hands.

I went back and groped about for my candle, which I found without difficulty and lighted. I then returned to the window to examine the catch. To my utter astonishment it was fastened with staples, driven deep into the sash, in such way that it could not possibly have been opened without the aid of tools. I tried it at every point. Not only was it securely fastened, but it could not possibly be opened without an expenditure of time and labor.

There was no doubt whatever that Morgan knew more about Glenarm House than I did. It was possible, but not likely, that he had crept past me in the corridor and gone out through the house, or by some other cellar window. My eyes were smarting from the smoke of the last shot, and my cheek stung where the burnt powder had struck my face. I was alive, but in my vexation and perplexity not, I fear, grateful for my safety. It was, however, some consolation to feel sure I had winged the enemy.

I gathered up the fragments of Morgan’s lantern and went back to the library. The lights in half the candlesticks had sputtered out. I extinguished the remainder and started to my room.
