"A moment only it held me, for that cold grasp filled me with such deep, shuddering abhorrence that I wrenched myself loose and fled madly across the court, stumbling again on the first step of the great staircase. I raced up the stairs, and even as I ran I heard the thing in pursuit.
"Up I went, and across the landing, and grasped the edge of the railing, for I meant to throw myself down from there, to a clean death on the floor below. But under my hands, the top of the railing moved, one of the great blocks that evidently made up its top was loosened and rocked toward me. In a flash I grasped the great block and staggered across the landing with it in my arms, to the head of the staircase. Two men could hardly have lifted it, I think, yet I did more, in a sudden access of mad strength; for as I heard that monster coming swiftly up the great stairs, I raised the block, invisible as ever, above my head, and sent it crashing down the staircase upon the place where I thought the thing was at that moment.
"For an instant after the crash there was silence, and then a low humming sound began, that waxed into a loud droning. And at the same time, at a spot half-way down the staircase where the block had crashed, a thin, purple liquid seemed to well out of the empty air, giving form to a few of the invisible steps as it flowed over them, and outlining, too, the block I had thrown, and a great hairy limb that lay crushed beneath it, and from which the fluid that was the monster's blood was oozing. I had not killed the thing, but had chained it down with the block that held it prisoner.
"There was a thrashing sound on the staircase, and the purple stream ran more freely, and by the outline of its splashes, I saw, dimly, the monstrous god that had been known in Mamurth in ages past. It was like a giant spider, with angled limbs that were yards long, and a hairy, repellent body. Even as I stood there, I wondered that the thing, invisible as it was, was yet visible by the life-blood in it, when that blood was spilled. Yet so it was, nor can I even suggest a reason. But one glimpse I got of its half-visible, purple-splashed outline, and then, hugging the farther side of the stairs, I descended. When I passed the thing, the intolerable odor of a crushed insect almost smothered me, and the monster itself made frantic efforts to loosen itself and spring at me. But it could not, and I got safely down, shuddering and hardly able to walk.
"Straight across the great court I went, and ran shakily through the corridor, and down the long avenue, and out between the two great statues. The moonlight shone on them, and the tablets of inscriptions stood out clearly on the sides of the statues, with their strange symbols and carved spider forms. But I knew now what their message was!
"It was well that my camels had wandered into the ruins, for such was the fear that struck through me that I would never have returned for them had they lingered by the invisible wall. All that night I rode to the north, and when morning came I did not stop, but still pushed north. And as I went through the mountain pass, one camel stumbled and fell, and in falling burst open all my water supplies that were lashed on its back.
"No water at all was left, but I still held north, killing the other camel by my constant speed, and then staggered on, afoot. On hands and knees I crawled forward, when my legs gave out, always north, away from that temple of evil and its evil god. And tonight, I had been crawling, how many miles I do not know, and I saw your fire. And that is all."
