Whilst occupied with my thoughts I had arrived at the low old-fashioned door of the Mill House. Unlocking it with the key, I passed inside. The hall was low and dark, the place smelt forlorn and mildewy. In spite of myself, I shivered. Did the woman who had come here “smiling to herself” a few days ago feel no chill of premonition as she entered this house? I wondered. Did the smile fade from her lips, and did a nameless dread close round her heart? Or had she gone upstairs, smiling still, unconscious of the doom that was so soon to overtake her? My heart beat a little faster. Was the house really empty? Was doom waiting for me in it also? For the first time, I understood the meaning of the much-used word, “atmosphere.” There was an atmosphere in this house, an atmosphere of cruelty, of menace, of evil.
