"A thousand times I prepared to go back on my word; a thousand tumultuous emotions of some impending disaster rushed through me. I felt on the border of an abyss, dark and hopeless; I was pushed on by invisible and unfriendly hands. I knew I must fall; I knew that those black depths would engulf me eternally. I took the plunge. We talked over Sedbergh days, and arranged our train to the North. Leethwaite looked very boyish, I thought, as he rose to go, and stood smiling in the doorway. "He was all kindness; I liked him more than ever. And yet, somehow, as we stood looking at one another, a grey shadow swept around him, and an icy pang shot through my heart. * * * * * "It was night once more, and the moonlight poured in floods from over the summit of the knoll where the uncanny boulders lay. Every object stood silhouetted against the dark background. A house, with its white walls, stood grim and silent; the paths running in various directions up and alongside the hill were made doubly clear by the whiteness of the beams that fell on them. There were no swift clouds, no mists to hide the brilliance of the stars, and it was nearly midnight. The air was cold, colder than is usual at Helvore, and I shivered. Leethwaite stood by my side. I glanced apprehensively at him. Why did he stand in the moonlight? What business had he there? I laughed, but I fear there was but little mirth in the sound. "'I wish you would stop that infernal noise,' he said; 'I am pretty nervous as it is.' "'All right,' I whispered; 'I won't do it again.' "But I did, and he edged sharply away from me. I looked over his head. There was the gaunt tree with the great hands. I fancied once again the branches were fingers. I told him so. "'For God's sake, man, keep quiet,' he replied. 'You are enough to upset any one's nerves.' He looked at his watch for the hundredth time. 'It's close on the hour.' "I again looked at the trees and listened. Suddenly, although there had been absolute silence before, I heard a faint breathing sound, a very gentle murmur. It came from over the distant knoll. At first very soft and low, but gradually getting louder and louder, it rushed past us into the wood beyond. I saw once more the great trees rock beneath it; and again I heard those voices--those of the woman and the man. "Leethwaite looked ill, very ill, I thought. I touched him on the arm. 'You are not frightened,' I said; 'you--a member of the New Supernatural Investigation Society?' "'Something is going to happen,' he gasped. 'I feel it--I know it. We shall see the murder--we shall know the secret of death. What is that?' "Away in the distance the tap-tapping of shoes came through the still night air. Tap--tap--tap, down the path from the knoll. "I clutched Leethwaite by the arm. 'You think you will see the murder, do you? And the murderer!' "Leethwaite didn't answer. His breath came in gasps; he looked about him like a man at bay.
