Three bal.u.s.traded galleries ran along on each side of the hall, one above the other.

"A four-storied house," grunted Conan, "and this hall extends to the roof. It's long as a street. I seem to see a door at the other end."

Valeria shrugged her white shoulders.

"Your eyes are better than mine, then, though I'm accounted sharp-eyed among the sea-rovers."

They turned into an open door at random, and traversed a series of empty chambers, floored like the hall, and with walls of the same green jade, or of marble or ivory or chalcedony, adorned with friezes of bronze, gold or silver. In the ceilings the green fire-gems were set, and their light was as ghostly and illusive as Conan had predicted. Under the witch-fire glow the intruders moved like specters.

Some of the chambers lacked this illumination, and their doorways showed black as the mouth of the Pit. These Conan and Valeria avoided, keeping always to the lighted chambers.

Cobwebs hung in the corners, but there was no perceptible acc.u.mulation of dust on the floor, or on the tables and seats of marble, jade or carnelian which occupied the chambers. Here and there were rugs of that silk known as Khitan which is practically indestructible. Nowhere did they find any windows, or doors opening into streets or courts. Each door merely opened into another chamber or hall.

"Why don't we come to a street?" grumbled Valeria. "This place or whatever we're in must be as big as the king of Turan's seraglio."

"They must not have perished of plague," said Conan, meditating upon the mystery of the empty city. "Otherwise we'd find skeletons. Maybe it became haunted, and everybody got up and left. Maybe----"

"Maybe, h.e.l.l!" broke in Valeria rudely. "We'll never know. Look at these friezes. They portray men. What race do they belong to?"

Conan scanned them and shook his head.

"I never saw people exactly like them. But there's the smack of the East about them--Vendhya, maybe, or Kosala."

"Were you a king in Kosala?" she asked, masking her keen curiosity with derision.

"No. But I was a war-chief of the Afghulis who live in the Himelian mountains above the borders of Vendhya. These people favor the Kosalans.

But why should Kosalans be building a city this far to west?"

The figures portrayed were those of slender, olive-skinned men and women, with finely chiseled, exotic features. They wore filmy robes and many delicate jeweled ornaments, and were depicted mostly in att.i.tudes of feasting, dancing or love-making.

"Easterners, all right," grunted Conan, "but from where I don't know.

They must have lived a disgustingly peaceful life, though, or they'd have scenes of wars and fights. Let's go up that stair."

It was an ivory spiral that wound up from the chamber in which they were standing. They mounted three flights and came into a broad chamber on the fourth floor, which seemed to be the highest tier in the building.

Skylights in the ceiling illuminated the room, in which light the fire-gems winked pallidly. Glancing through the doors they saw, except on one side, a series of similarly lighted chambers. This other door opened upon a bal.u.s.traded gallery that overhung a hall much smaller than the one they had recently explored on the lower floor.

"h.e.l.l!" Valeria sat down disgustedly on a jade bench. "The people who deserted this city must have taken all their treasures with them. I'm tired of wandering through these bare rooms at random."

"All these upper chambers seem to be lighted," said Conan. "I wish we could find a window that overlooked the city. Let's have a look through that door over there."

"You have a look," advised Valeria. "I'm going to sit here and rest my feet."

Conan disappeared through the door opposite that one opening upon the gallery, and Valeria leaned back with her hands clasped behind her head, and thrust her booted legs out in front of her. These silent rooms and halls with their gleaming green cl.u.s.ters of ornaments and burning crimson floors were beginning to depress her. She wished they could find their way out of the maze into which they had wandered and emerge into a street. She wondered idly what furtive, dark feet had glided over those flaming floors in past centuries, how many deeds of cruelty and mystery those winking ceiling-gems had blazed down upon.

It was a faint noise that brought her out of her reflections. She was on her feet with her sword in her hand before she realized what had disturbed her. Conan had not returned, and she knew it was not he that she had heard.

The sound had come from somewhere beyond the door that opened on to the gallery. Soundlessly in her soft leather boots she glided through it, crept across the balcony and peered down between the heavy bal.u.s.trades.

_A man was stealing along the hall._

The sight of a human being in this supposedly deserted city was a startling shock. Crouching down behind the stone bal.u.s.ters, with every nerve tingling, Valeria glared down at the stealthy figure.

The man in no way resembled the figures depicted on the friezes. He was slightly above middle height, very dark, though not negroid. He was naked but for a scanty silk clout that only partly covered his muscular hips, and a leather girdle, a hand's breadth broad, about his lean waist. His long black hair hung in lank strands about his shoulders, giving him a wild appearance. He was gaunt, but knots and cords of muscles stood out on his arms and legs, without that fleshy padding that presents a pleasing symmetry of contour. He was built with an economy that was almost repellent.

Yet it was not so much his physical appearance as his att.i.tude that impressed the woman who watched him. He slunk along, stooped in a semi-crouch, his head turning from side to side. He grasped a wide-tipped blade in his right hand, and she saw it shake with the intensity of the emotion that gripped him. He was afraid, trembling in the grip of some dire terror. When he turned his head she caught the blaze of wild eyes among the lank strands of black hair.

He did not see her. On tiptoe he glided across the hall and vanished through an open door. A moment later she heard a choking cry, and then silence fell again.

Consumed with curiosity, Valeria glided along the gallery until she came to a door above the one through which the man had pa.s.sed. It opened into another, smaller gallery that encircled a large chamber.

This chamber was on the third floor, and its ceiling was not so high as that of the hall. It was lighted only by the fire-stones, and their weird green glow left the s.p.a.ces under the balcony in shadows.

Valeria's eyes widened. The man she had seen was still in the chamber.

He lay face down on a dark crimson carpet in the middle of the room. His body was limp, his arms spread wide. His curved sword lay near him.

She wondered why he should lie there so motionless. Then her eyes narrowed as she stared down at the rug on which he lay. Beneath and about him the fabric showed a slightly different color, a deeper, brighter crimson.

Shivering slightly, she crouched down closer behind the bal.u.s.trade, intently scanning the shadows under the overhanging gallery. They gave up no secret.

Suddenly another figure entered the grim drama. He was a man similar to the first, and he came in by a door opposite that which gave upon the hall.

His eyes glared at the sight of the man on the floor, and he spoke something in a staccato voice that sounded like "Chicmec!" The other did not move.

The man stepped quickly across the floor, bent, gripped the fallen man's shoulder and turned him over. A choking cry escaped him as the head fell back limply, disclosing a throat that had been severed from ear to ear.

The man let the corpse fall back upon the blood-stained carpet, and sprang to his feet, shaking like a wind-blown leaf. His face was an ashy mask of fear. But with one knee flexed for flight, he froze suddenly, became as immobile as an image, staring across the chamber with dilated eyes.

In the shadows beneath the balcony a ghostly light began to glow and grow, a light that was not part of the fire-stone gleam. Valeria felt her hair stir as she watched it; for, dimly visible in the throbbing radiance, there floated a human skull, and it was from this skull--human yet appallingly misshapen--that the spectral light seemed to emanate. It hung there like a disembodied head, conjured out of night and the shadows, growing more and more distinct; human, and yet not human as she knew humanity.

The man stood motionless, an embodiment of paralyzed horror, staring fixedly at the apparition. The thing moved out from the wall and a grotesque shadow moved with it. Slowly the shadow became visible as a man-like figure whose naked torso and limbs shone whitely, with the hue of bleached bones. The bare skull on its shoulders grinned eyelessly, in the midst of its unholy nimbus, and the man confronting it seemed unable to take his eyes from it. He stood still, his sword dangling from nerveless fingers, on his face the expression of a man bound by the spells of a mesmerist.

Valeria realized that it was not fear alone that paralyzed him. Some h.e.l.lish quality of that throbbing glow had robbed him of his power to think and act. She herself, safely above the scene, felt the subtle impact of a nameless emanation that was a threat to sanity.

The horror swept toward its victim and he moved at last, but only to drop his sword and sink to his knees, covering his eyes with his hands.

Dumbly he awaited the stroke of the blade that now gleamed in the apparition's hand as it reared above him like Death triumphant over mankind.

Valeria acted according to the first impulse of her wayward nature. With one tigerish movement she was over the bal.u.s.trade and dropping to the floor behind the awful shape. It wheeled at the thud of her soft boots on the floor, but even as it turned, her keen blade lashed down, and a fierce exultation swept her as she felt the edge cleave solid flesh and mortal bone.

The apparition cried out gurglingly and went down, severed through shoulder, breast-bone and spine, and as it fell the burning skull rolled clear, revealing a lank mop of black hair and a dark face twisted in the convulsions of death. Beneath the horrific masquerade there was a human being, a man similar to the one kneeling supinely on the floor.

The latter looked up at the sound of the blow and the cry, and now he glared in wild-eyed amazement at the white-skinned woman who stood over the corpse with a dripping sword in her hand.
