A great black shadow lay across the land, cleaving the red flame of the red sunset. To the man who toiled up the jungle trail it loomed like a symbol of death and horror, a menace brooding and terrible, like the shadow of a stealthy assassin flung upon some candle-lit wall.Yet it was only the shadow of the great crag which reared up in front of him, the first outpost of the grim foothills which were his goal. He halted a moment at its foot, staring upward where it rose blackly limned against the dying sun. He could have sworn that he caught the hint of a movement at the top, as he stared, hand shielding his eyes, but the fading glare dazzled him and he could not be sure. Was it a man who darted to cover? A man, or-?He shrugged his shoulders and fell to examining the rough trail which led up and over the brow of the crag. At first glance it seemed that only a mountain goat could scale it, but closer investigation showed numbers of finger holds drilled into the solid rock. It would be a task to try his powers to the utmost but he had not come a thousand miles to turn back now.He dropped the large pouch he wore at his shoulder, and laid down the clumsy musket, retaining only his long rapier, dagger, and one of his pistols, these he strapped behind him, and without a backward glance over the darkening trail he had come, he started the long ascent.He was a tall man, long-armed and iron-muscled, yet again and again he was forced to halt in his upward climb and rest for a moment clinging like an ant to the precipitous face of the cliff. Night fell swiftly and the crag above him was a shadowy blur in which he was forced to feel with his fingers, blindly, for the holes which served him as a precarious ladder.Below him, the night noises of the tropical jungle broke forth, yet it appeared to him that even these sounds were subdued and hushed as though the great black hills looming above threw a spell of silence and fear even over the jungle creatures.On up he struggled, and now to make his way harder, the cliff bulged outward near its summit, and the strain on nerve and muscle became heart-breaking. Time and again a hold slipped and he escaped falling by a hair's breadth. But every fibre in his lean hard body was perfectly co-ordinated, and his fingers were like steel talons with the grip of a vice. His progress grew slower and slower but on he went until at last he saw the cliffy brow splitting the stars a scant twenty feet above him.And even as he looked, a vague bulk heaved into view, toppled on the edge and hurtled down toward him with a great rush of air about it. Flesh crawling, he flattened himself against the cliff's face and felt a heavy blow against his shoulder, only a glancing blow, but even so it nearly tore him from his hold, and as he fought desperately to right himself, he heard a reverberating crash among the rocks far below. Cold sweat beading his brow, he looked up. Who-or what-had shoved that boulder over the cliff edge? He was brave, as the bones on many a battlefield could testify, but the thought of dying like a sheep, helpless and with no chance of resistance, turned his blood cold.Then a wave of fury supplanted his fear and he renewed his climb with reckless speed. The expected second boulder did not come, however, and no living thing met his sight as he clambered up over the edge and leaped erect, sword flashing from its scabbard.He stood upon a sort of plateau which debouched into a very broken hilly country some half mile to the west. The crag he had just mounted jutted out from the rest of the heights like a sullen promontory, looming above the sea of waving foliage below, now dark and mysterious in the tropic night.
