Slowly the curtain shook and its folds dissolved as I moved against the wind. The clouds lifted; and by degrees I grew aware that I was standing on the barren moor. Night was stretched around to the horizon, where straight ahead a grey bar shone across the gloom. I pressed on towards it. The heath was uneven under my feet, and now and then I stumbled heavily; but still I held on. For it seemed that I must get to this grey bar or die a second time. All my muscles, all my will, were strained upon this purpose.
Drawing nearer, I observed that a wave-like motion kept passing over this brighter space, as it had passed over the mirror. The glimmer would be obscured for a moment, and then re-appear. At length a gentle acclivity of the moor hid it for a while. My legs positively raced up this slope, and upon the summit I hardly dared to look for a moment, knowing that if the light were an illusion all my hope must die with it.
But it was no illusion. There was the light, and there, before my feet, lay a sable sheet of water, over the surface of which the light was playing. There was no moon, no star in heaven; yet over this desolate tarn hovered a pale radiance that ceased again where the edge of its waves lapped the further bank of peat. Their monotonous wash hardly broke the stillness of the place.
The formless longing was now pulling at me with an attraction I could not deny, though within me there rose and fought against it a horror only less strong. Here, as in the Blue Room, two souls were struggling for me. It was the soul of Philip Cardinnock that drew me towards the tarn and the soul of Samuel Wraxall that resisted. Only, what was the thing towards which I was being pulled?
I must have stood at least a minute on the brink before I descried a black object floating at the far end of the tarn. What this object was I could not make out; but I knew it on the instant to be that for which I longed, and all my will grew suddenly intent on drawing it nearer. Even as my volition centred upon it, the black spot began to move slowly out into the pale radiance towards me. Silently, surely, as though my wish drew it by a rope, it floated nearer and nearer over the bosom of the tarn; and while it was still some twenty yards from me I saw it to be a long black box, shaped somewhat like a coffin.
There was no doubt about it. I could hear the water now sucking at its dark sides. I stepped down the bank, and waded up to my knees in the icy water to meet it. It was a plain box, with no writing upon the lid, nor any speck of metal to relieve the dead black: and it moved with the same even speed straight up to where I stood.
As it came, I laid my hand upon it and touched wood. But with the touch came a further sensation that made me fling both arms around the box and begin frantically to haul it towards the shore.
It was a feeling of suffocation; of a weight that pressed in upon my ribs and choked the lungs' action. I felt that I must open that box or die horribly; that until I had it upon the bank and had forced the lid up I should know no pause from the labour and torture of dying.
This put a wild strength into me. As the box grated upon the few pebbles by the shore, I bent over it, caught it once more by the sides, and with infinite effort dragged it up out of the water. It was heavy, and the weight upon my chest was heavier yet: but straining, panting, gasping, I hauled it up the bank, dropped it on the turf, and knelt over it, tugging furiously at the lid.
I was frenzied—no less. My nails were torn until the blood gushed. Lights danced before me; bells rang in my ears; the pressure on my lungs grew more intolerable with each moment; but still I fought with that lid. Seven devils were within me and helped me; and all the while I knew that I was dying, that unless the box were opened in a moment or two it would be too late.
