I may have spoken significantly; she may have been at that moment peculiarly sharp to read the meanings behind plain sentences. Whatever the case, her face lit up with joy--the characteristic, joyful expression that never comes to the faces of men and few times to the face of a woman. For a moment youth seemed to return to her. The last traces of the limber strength of body, gone with her girlhood, came back. She wore no longer, at that second, the mien of a nun of household service. She was transfigured. "It's Monty Cranch!" she cried under her breath. "He isn't dead! I knew he wasn't. I knew it always." "Go now," I said. "Mr. Estabrook has something of a story to tell you." She left me then, standing alone before that white expanse of door. I was literally and figuratively on the threshold of poor MacMechem's mystery, knowing well that the solution of it would explain the strange influence that had registered its effects upon my patient, little Virginia Marbury. I listened with my ear pressed softly against the door. No other sign of life came to me than that of soft breathing. Indeed, even then I had to admit to myself that I might have imagined the sound. I stood back, as one does in such circumstances, half afraid to act--half afraid that to touch the knob or assault the closed and silent room would be to bring the sky crashing down to earth, turn loose a pestilence, set a demon free, or expose some sight grisly enough to turn the observer to stone. I found myself sensing the presence of a person or persons behind the opaque panels; my eyes were trying, as eyes will, to look through the painted wooden barrier. My glance wandered to the top of the door, back again to the middle, downward toward the bottom. The house was so still, now that Margaret had stepped out of it into the vestibule, that the ears imagined that they heard the beating of great velvety black wings. The gloom of the drawn blinds produced strange shadows, in which the eyes endeavored to find lurking, unseen things that watched the conduct and the destinies of men. But my eyes and ears returned again each time to their vain attention to the entrance of that room, as if the stillness and the gloom bade me listen and look, while I stood there hesitant. At last the reason for my hesitancy, the reason for my reluctance, the reason for my staring, suddenly appeared as if some fate had directed my observation. A corner of an envelope was protruding from beneath the door! I felt as I pulled the envelope through that the next moment might bring a piteous outcry from within, as if I had drawn upon the vital nerves of an organism. Yet none came; I found myself erect once more with the envelope in my hand, reading the writing on its face. It was scrawled in a trembling hand. "Margaret," it said, "send for my husband. Give him this envelope without opening it yourself. Give it to him before he comes to this door."
