And the discovery revived in me a far stronger emotion than any mere desire for immediate explanation. Not only did I not insist upon an answer, but I was actually terrified lest she would answer. More, I felt in me a terror lest I should be moved to describe my own experiences below-stairs, thus increasing their reality and so the reality of all. She might even explain them too! Still listening intently, she raised her head and looked me in the eyes. Her lips opened to speak. The words came to me from a great distance, it seemed, and her voice had a sound like a stone that drops into a deep well, its fate though hidden, known. "We are in it with her, too, Bill. We are in it with her. Our interpretations vary--because we are--in parts of it only. Mabel is in it--all." The desire for violence came over me. If only she would say a definite thing in plain King's English! If only I could find it in me to give utterance to what shouted so loud within me! If only--the same old cry-- something would happen! For all this elliptic talk that dazed my mind left obscurity everywhere. Her atrocious meaning, nonetheless, flashed through me, though vanishing before it wholly divulged itself. It brought a certain reaction with it. I found my tongue. Whether I actually believed what I said is more than I can swear to; that it seemed to me wise at the moment is all I remember. My mind was in a state of obscure perception less than that of normal consciousness. "Yes, Frances, I believe that what you say is the truth, and that we are in it with her"--I meant to say I with loud, hostile emphasis, but instead I whispered it lest she should hear the trembling of my voice-- "and for that reason, my dear sister, we leave tomorrow, you and I-- today, rather, since it is long past midnight--we leave this house of the damned. We go back to London." Frances looked up, her face distraught almost beyond recognition. But it was not my words that caused the tumult in her heart. It was a sound-- the sound she had been listening for--so faint I barely caught it myself, and had she not pointed I could never have known the direction whence it came. Small and terrible it rose again in the stillness of the night, the sound of gnashing teeth. And behind it came another--the tread of stealthy footsteps. Both were just outside the door. The room swung round me for a second. My first instinct to prevent my sister going out--she had dashed past me frantically to the door--gave place to another when I saw the expression in her eyes. I followed her lead instead; it was surer than my own. The pistol in my pocket swung uselessly against my thigh. I was flustered beyond belief and ashamed that I was so. "Keep close to me, Frances," I said huskily, as the door swung wide and a shaft of light fell upon a figure moving rapidly. Mabel was going down the corridor. Beyond her, in the shadows on the staircase, a second figure stood beckoning, scarcely visible.
