Something impelled me to go below, and, taking a lantern, I tramped somberly through the cellar, glanced at the heating apparatus, and, remembering that the chapel entrance to the tunnel was unguarded, followed the corridor to the trap, and opened it. The cold air blew up sharply and I thrust my head down to listen. A sound at once arrested me. I thought at first it must be the suction of the air, but Glenarm House was no place for conjectures, and I put the lantern aside and jumped down into the tunnel. A gleam of light showed for an instant, then the darkness and silence were complete. I ran rapidly over the smooth floor, which I had traversed so often that I knew its every line. My only weapon was one of Stoddard’s clubs. Near the Door of Bewilderment I paused and listened. The tunnel was perfectly quiet. I took a step forward and stumbled over a brick, fumbled on the wall for the opening which we had closed carefully that afternoon, and at the instant I found it a lantern flashed blindingly in my face and I drew back, crouching involuntarily, and clenching the club ready to strike. “Good evening, Mr. Glenarm!” Marian Devereux’s voice broke the silence, and Marian Devereux’s face, with the full light of the lantern upon it, was bent gravely upon me. Her voice, as I heard it there,—her face, as I saw it there,—are the things that I shall remember last when my hour comes to go hence from this world. The slim fingers, as they clasped the wire screen of the lantern, held my gaze for a second. The red tam-o’-shanter that I had associated with her youth and beauty was tilted rakishly on one side of her pretty head. To find her here, seeking, like a thief in the night, for some means of helping Arthur Pickering, was the bitterest drop in the cup. I felt as though I had been struck with a bludgeon. “I beg your pardon!” she said, and laughed. “There doesn’t seem to be anything to say, does there? Well, we do certainly meet under the most unusual, not to say unconventional, circumstances, Squire Glenarm. Please go away or turn your back. I want to get out of this donjon keep.” She took my hand coolly enough and stepped down into the passage. Then I broke upon her stormily. “You don’t seem to understand the gravity of what you are doing! Don’t you know that you are risking your life in crawling through this house at midnight? —that even to serve Arthur Pickering, a life is a pretty big thing to throw away? Your infatuation for that blackguard seems to carry you far, Miss Devereux.” She swung the lantern at arm’s length back and forth so that its rays at every forward motion struck my face like a blow. “It isn’t exactly pleasant in this cavern. Unless you wish to turn me over to the lord high executioner, I will bid you good night.” “But the infamy of this—of coming in here to spy upon me—to help my enemy—the man who is seeking plunder—doesn’t seem to trouble you.”
