I saw the boy sway nearer in his weakness, and the sudden flash of a knife. There was a little choking gurgle, and they all crashed down together, with the youngster underneath. And when the madman rose the boy lay still, with the shaft of the knife sticking out from his coat above his heart.
It was then that Rupert Carlingham laughed again, while his wife, mad with grief, knelt beside the dead boy, pillowing his head on her lap. For what seemed an eternity I stood watching, unable to move or speak; then the murderer bent down and swung his wife over his shoulder. And, before I realized what he was going to do, he had left the room, and I saw him passing the window outside.
The sight galvanised me into action; there was just a possibility I might avert a double tragedy. With a loud shout I dashed out of the front door, and down the ill-kept drive; but when I got to the open ground he seemed to have covered an incredible distance, considering his burden. I could see him shambling over the turf, up the side of the valley which led to the headland where the rain had caught me; and, as fast as I could, I followed him, shouting as I ran. But it was no use—gain on him I could not. Steadily, with apparent ease, he carried the girl up the hill, taking no more notice of my cries than he had of my presence earlier in the evening. And, with the water squelching from my boots, I ran after him—no longer wasting my breath on shouting, but saving it all in my frenzied endeavour to catch him before it was too late. For once again I knew what was going to happen, even as I had known when I heard the footsteps coming down the stairs.
I was still fifty yards from him when he reached the top of the cliff; and for a while he paused there silhouetted against the angry sky. He seemed to be staring out to sea, and the light from the flaming red sunset, under the black of the storm, shone on his great, gaunt figure, bathing it in a wonderful splendour. The next moment he was gone.... I heard him give one loud cry; then he sprang into space with the girl still clasped in his arms.
And when I reached the spot and peered over, only the low booming of the sullen Atlantic three hundred feet below came to my ears.... That, and the mocking shrieks of a thousand gulls. Of the madman and his wife there was no sign.
At last I got up and started to walk away mechanically. I felt that somehow I was to blame for the tragedy, that I should have done something, taken a hand in that grim fight. And yet I knew that if I was called upon to witness it again, I should act in the same way. I should feel as powerless to move as I had felt in that ill-omened house, with the candles guttering on the mantelpiece, and the lightning flashing through the dirty window. Even now I seemed to be moving in a dream, and after a while I stopped and made a determined effort to pull myself together.
"You will go back," I said out loud, "to that house. And you will make sure that that boy is dead. You are a grown man, and not an hysterical woman. You will go back."
And as if in answer a seagull screamed discordantly above my head. Not for five thousand pounds would I have gone back to that house alone, and when I argued with myself and said, "You are a fool, and a coward," the gull shrieked mockingly again.
"What is there to be afraid of?" I cried. "A dead body; and you have seen many hundreds."
It was as I asked the question out loud that I came to a road and sat down beside it. It was little more than a track, but it seemed to speak of other human beings, and I wanted human companionship at the moment—wanted it more than I had ever wanted anything in my life. At any other time I would have resented sharing with strangers the glorious beauty of the moors as they stretched back to a rugged tor a mile or two away, with their wonderful colouring of violet and black, and the scent of the wet earth rising all around. But now...
