There was every reason to suspect that something inimical to human beings haunted this maze. What if the ornate door in the dungeon led out to this ravine?
A careful search disclosed the door whose existence Conan suspected. The thin cracks that betrayed its presence would have escaped the casual glance. On the side of the ravine, the door looked like the material of the cliff and fitted perfectly. Conan thrust powerfully at it, but it did not yield. He remembered its heavy, metal-bound construction and stout bolts. It would take a battering ram to shake that door. The strength of the door, together with the projecting blades overhead, implied' that the Yezmites were taking no chances that the haunter of the gulches might get into their city. On the other hand, there was comfort in the thought that it must be a creature of flesh and blood, not a demon against whom bolts and spikes would be of no avail.
Conan looked down the gully toward the mysterious labyrinth, wondering what skulking horror its mazes hid. The sun had not yet set but was hidden from the bottoms of the gulches. Although vision was still clear, the ravine was full of shadows.
Then Conan became aware of another sound: a muffled drumming, a slow boom … boom … boom, as if the drummer were striking alternate beats for marching men. There was something odd about the quality of the sound. Conan knew the clacking hollow log-drums of the Kushites, the whirring copper kettledrums of the Hyrkanians, and the thundering infantry drums of the Hyborians, but this did not sound like any of these. He glanced back at Yanaidar, but the sound did not seem to come from the city. It seemed to come from everywhere and nowhere … from beneath his feet as much as anything.
Then the sound ceased.
A mystical blue twilight hovered over the gulches as Conan reentered the labyrinth. Threading among winding channels, he came out into a slightly wider gully, which Conan believed was the one he had seen from the ridge, which ran to the south wall of the bowl. But he had not gone fifty yards when it split on a sharp spur into two narrower gorges. This division had not been visible from the ridge, and Conan did not know which branch to follow.
As he hesitated, peering along his alternative paths, he suddenly stiffened.
Down the right-hand ravine, a still narrower gulch opened into it, forming a well of blue shadows. And in that well something moved. Conan tensed rigidly as he stared at the monstrous, manlike thing that stood in the twilight before him.
It was like ghoulish incarnation of a terrible legend, clad in flesh and bone; a giant ape, as tall on its gnarled legs as a gorilla. It was like the monstrous man-apes that hunted the mountains around the Vilayet Sea, which Conan had seen and fought before. But it was even larger; its hair was longer and shaggier, as of an arctic beast, and paler, an ashen grey that was almost white.
Its feet and hands were more manlike than those of a gorilla, the great toes and thumbs being more like those of man than of the anthropoid. It was no tree-dweller but a beast bred on great plains and gaunt mountains. The face was apish in general appearance, though the nose-bridge was more pronounced, the jaw less bestial. But its manlike features merely increased the dreadfulness of its aspect, and the intelligence which gleamed from its small red eyes was wholly malignant.
Conan knew it for what it was: the monster named in myth and legend of the north … the snow ape, the desert man of forbidden Pathenia. He had heard rumors of its existence in wild tales drifting down from the lost, bleak plateau country of Loulan. Tribesmen had sworn to the stories of a manlike beast, which had dwelt there since time immemorial, adapted to the famine and bitter chill of the northern uplands.
All this flashed through Conan's mind as the two stood facing each other in menacing tenseness. Then the rocky walls of the ravine echoed to the ape's high, penetrating scream as it charged, low-hanging arms swinging wide, yellow fangs bared and dripping.
Conan waited, poised on the balls of his feet, craft and long knife pitted against the strength of the mighty ape.
The monster's victims had been given to it broken and shattered from torture, or dead. The semi-human spark in its brain, which set it apart from the true beasts, had found a horrible exultation in the death agonies of its prey. This man was only another weak creature to be torn and dismembered, and his skull broken to get at the brain, even though he stood up with a gleaming thing in his hand.
Conan, as he faced that onrushing death, knew his only chance was to keep out of the grip of those huge arms, which could crush him in an instant. The monster was swifter than its clumsy appearance indicated. It hurled itself through the air for the last few feet in a giant grotesque spring. Not until it was looming over him, the great arms closing upon him, did Conan move, and then his action would have shamed a striking leopard.
The talonlike nails only shredded his ragged tunic as he sprang clear, slashing, and a hideous scream ripped echoing through the ridges. The ape's right hand was half severed at the wrist. The thick mat of pale hair prevented Conan's slash from altogether severing the member. With blood spouting from the wound, the brute wheeled and rushed again. This time its lunge was too lightning-quick for any human thews to avoid.
Conan evaded the disembowelling sweep of the great misshapen left hand with its thick black nails, but the massive shoulder struck him and knocked him staggering. He was carried to the wall with the lunging brute, but even as he was swept back he drove his knife to the hilt in the great belly and ripped up in desperation in what he thought was his dying stroke.
They crashed together into the wall. The ape's great arm hooked terrifyingly about Conan's straining frame. The scream of the beast deafened him as the foaming jaws gaped above his head. Then they snapped in empty air as a great shudder shook the mighty body. A frightful convulsion hurled the Cimmerian clear, and he staggered up to see the ape thrashing in its death throes at the foot of the wall. His desperate upward rip had disembowelled it, and the tearing blade had plowed up through muscle and bone to find the anthropoid's fierce heart.
Conan's corded muscles were quivering as if from a long strain. His iron-hard frame had resisted the terrible strength of the ape long enough to let him come alive out of that awful grapple, which would have torn a weaker man to pieces.
But the terrific exertion had shaken even him. His tunic had been ripped nearly off his body and some links of the mail-shirt underneath were broken. Those horny-taloned fingers had left bloody marks across his back. He stood panting as if from a long run, smeared with blood, his own and the ape's.
Conan shuddered, then stood in thought as the red sun impaled itself on a far peak. The pattern was becoming clear now. Broken captives were thrown out to the ape through the door in the city wall. The ape, like those that lived around the Sea of Vilayet, ate flesh as well as fodder. But the irregular supply of captives would not satisfy the enormous appetite of so large and active a beast.
Therefore the Yezmites must feed it a regular ration; hence the remains of melons and turnips.
Conan swallowed, aware of thirst. He had rid the ravines of their haunter, but he could still perish of hunger and thirst if he did not find a way out of the depression. There was no doubt a spring or pool somewhere in the waste, where the ape had drunk, but it might take a month to find it.
Dusk masked the gullies and hung over the ridges as Conan moved off down the right-hand ravine. Forty paces further, the left branch rejoined its brother. As he advanced, the walls were more thickly pitted with cave-like lairs, in which the rank scent of the ape hung strongly. It occurred to him that there might be more than one of the creatures, but that was unlikely, because the scream of the first as it charged would have attracted any others.
