The girl turned away. "Oh, very well," she said flatly, "if you don't want me with you."

"That's a good scout. I'll be back just as quickly as I can. And, by the way, lock the door from the inside, and don't open it till you hear my voice."

The girl looked at him wonderingly. "But--" she began.

"Don't ask me why. Do it." There was a curious note in Allan's voice, one that cut off Naomi's question. The door shut, and Dane heard the bolt shoot home.

He stood in the corridor, listening intently, his face strained. There was no sound save that of Naomi's movements behind the locked door.

Allan turned to search for the auxiliary staircase that must be somewhere near the bank of ascendor doors.

Silence was again around him, almost tangible in its heaviness. His footsteps reverberated through dead halls, the echo curiously m.u.f.fled by the coating of slime that spread dankly green. Allan found the staircase well, descended cautiously, pausing often to listen. Not even the faint scuttering of vermin rewarded him.

At last, three stories down, he reached the stores level. Here, in a great open hall, were the numerous alcoved recesses of the shops. Once thronged, and gaudy with the varicolored goods brought by plane and heavy-bellied rocket-freighter from both hemispheres, the vast s.p.a.ce was a desert of moldering dust heaps, brooding. There was a faint odor in the stagnant air--of spices, and rustling silks, of rare perfumes, of all the luxury of the Golden Age that Man's folly had ended.

Allan searched the long shelves feverishly, a nervous urge to complete his task and get back to Naomi tingling in his veins. Once he stopped suddenly, his body twisting to the stair landing. He seemed to have heard something, an indefinable thudding, the shadow of a sound. But it did not come again, and he dismissed it as the thumping of his own blood in his ears, audible in that stillness.

At the end of a long aisle, neat rows of cans greeted him, the labels rotted off, the metal rust-streaked, but apparently tight and whole.

He found a metal basket, a roll of wire, twisted a handle for the basket and filled it, choosing the cans by their shape. He should have liked to explore further, but the urge to return tugged at him. He went up the stairs three at a time.

There was a dark, oblong break in the long glowing wall of the upper corridor! The door--it was the door of the apartment where he had left Naomi! He leaped down the hall, shouting. The portal hung open, shattered: the rooms were stark, staring empty. Allan reeled out again. There were the marks of footprints, of many footprints, in the green sc.u.m of the hall floor, their own among them, that had led the marauders straight to the girl!

Fool that he had been! He had thought she would be safer behind a bolted door! Allan berated himself. He had thought not to worry her.

There had been only four bodies in the wreckage of the black plane--but how had the rest gotten here so soon?

There was a humming whine from above. Dane hurtled toward the roof stairs. He burst from the upper landing, fists clenched, face a furious mask. A helicopter was just rising. Allan jumped for it, his fingers caught and clung to the undercarriage. But the down-swing of his body broke his hold, and Dane crashed to the roof.

He watched the plane, saw it zoom up, turn east, saw it sink and land a half mile away, atop the building where he had found her. In the moonlight he marked the direction of the place, its distance. Then he was descending stairs, innumerable stairs. He could not hope to reach it in time to save Naomi. But--his eyes grew stony--he could avenge her.

Afterwards that nightmare journey through the murdered city was a detailless blur to Allan. He clambered over heaped rubble, forced himself through windrows of piled bones that crumbled to dust at his touch. Vines, and whipping creepers of triumphant vegetation everywhere halted him; he tore them away with bleeding hands and stumbled on. He fell, and scrambled up again, and plodded on the interminable path till he had reached his goal.

Here, at last, some modic.u.m of reason penetrated into the numbed blankness of his brain. The dark arch of the entrance-way was somehow familiar. Still legible under the verdigris of the bronze plate on the lintel he read, "Transportation Substation--District L2ZX." Now he understood why he had not seen the black flier till it had leaped in pursuit: how it was that Naomi's captors had so quickly found another 'copter. A broad well penetrated the center of this building--its opening must be covered by the luxuriant vines so that he had not noted it--and dropped down to the midsection that was a hangar for local and private planes. His own little Zenith had been stored here on occasion. There must be other helicopters there, and a stock of fuel. A dim plan began to form at the back of his head.

But first he must find where they were, and what had happened to Naomi.

Allan removed his sandals, and began the endless climb. He made no sound on the steps, cushioned as they were with mold, but at each landing he paused for a moment, listening. The cold fire that burned within him left no room for fatigue, for pain.

A murmuring, then a laugh, cut through the deathlike stillness. Allan was nearly to the top. Down the corridor into which he crept, snakelike on his belly, red light flickered from an open door.

Dane moved soundlessly to that door, and, lying flat, pushed his head slowly past the sash till he could see within. By the light of a fire that danced in the center of the unburnable mallite floor, its illumination half revealing their sodden, brutish faces, he saw an unspeakably strange group. A scene from out of the dawn of history it was, the haunch-squatted circle, their yellow skins and black glistening in the crimson, shifting glow. He recognized the giant Negro, Ra-Jamba, his head bound with a rag, and Jung Sin. There were five others cl.u.s.tered about those two, and a third, a skew-eyed Oriental, intent on some game they were playing with little sticks that pa.s.sed from hand to hand.

Before each of the players there was a little pile of fish bones, black with much handling. The Negro's pile, and that of Jung Sin, were about equal, but there were only two or three in front of the third player. And just as Allan caught sight of them, the sticks clicked, and a shrill objurgation burst from that third as the last of his markers were raked in by Jung Sin's taloned hand. The circle hunched closer, there was a ribald, taunting laugh from Ra-Jamba and Jung Sin glanced over his shoulder into a shadowed corner.

"Have patience, my lotus flower," he purred. "Only one is left. Soon the G.o.ddess of fortune and love will clear him from my path. By the nine-headed Dragon, I have never seen a game of Li-Fan last so long.

But it draws to an end. Then we shall have our joy together, you and I."

In that instant the fire flared. Allan saw an open window in the background, and beneath it a slim white form lying, bound and helpless. Fierce joy leaped in him, and fiercer hate, Naomi was as yet untouched, the game was being played for her as stake. He had come in time to save her!

But how? There were eight of the Easterners in the room. He had his ray-gun, and might cow them with it and free the girl. But as soon as he had gotten her out of the room, they would surge out after the whites. He could fight for a while, but the end was inevitable. And even if by some miracle he and Naomi escaped, they would be tracked to Sugar Loaf.

The sticks were clicking in a continuous rattle as the final bout of the game waxed fast and furious. And as fast and furious was the whirl of Allan's thoughts. He strove to remember the layout of this building. The helicopter hangar was next above this level. Outside the windows of this floor a narrow ledge ran. The nebulous scheme that had entered his dazed brain as he read the bronze plate below took clearer form, shaped itself to meet this new need.

Allan crept away to safe distance, leaped to his feet and flitted upward. He was in the empty, echoing s.p.a.ce of the hangar level. The fuel tanks bulged huge in the dimness. Here were reels of the feed hose he needed--flexible metal that had withstood the years; here a faucet nozzle, and a long coil of fine wire. Haste driving him, he made the connections. Then he was descending again, dragging behind him a long black snake of hose whose other end was clamped to a vat of oxygen impregnated gasoline.

The rustle of the hose along the hall floor was m.u.f.fled by the greasy slime. Dane got the nozzle to just outside the door of the room where Naomi lay captive. The rattle of the playing sticks still continued.

Jung Sin's voice sounded, in a language that Allan did not understand.

But there was no mistaking the triumphant note in the silky, jeering tones. The yellow man was winning, and winning fast.

Dane twisted one end of the wire around the faucet handle. Then he was unwinding the coil as he tried the door of the chamber next to the one where the fire burned, found it open, darted across the room and softly raised the sash. The sill here, like the one beneath which Naomi lay, was a bare two feet above the ground.

He was out on the ledge, sliding along it toward the fire-reddened oblong five feet away. He crammed his body close against the wall, kept his eyes away from the unfenced edge of that eighteen-inch shelf.

Beyond, an abyss waited, twelve thousand feet of nothingness down which a single misstep, an instant's vertigo, would send him hurtling.

Suddenly the rattle of sticks stopped, and he heard the black's long howl of disappointed rage. The game was over!

Allan reached the window, glimpsed a leering semicircle of animal faces, saw Jung Sin coming toward him. Then he had swung in.

"Back, Jung Sin! Back!" Allan was straddled over Naomi's form, the ray-gun thrust out before his tense threat, his face livid, his eyes blazing. "Get back, or I ray you!"

Consternation, awe, flashed into the brutal faces of the Easterners.

Jung Sin reeled back, his saffron hands rising. Allan's weapon swept slowly along the line of staring men. "If one of you moves I flash."

He bent to the girl, keeping his eyes on the Easterners, and his weapon steady. He had hung the wire coil over his shoulder, leaving his left hand free to fumble for and untie the cords around Naomi's wrists. He got them loose.

"Can you get your feet free, Naomi?"

"Yes, I can manage it." Her voice was steady, but there was a great thankfulness vibrant in it.

"Then do it and get out on the ledge. Quick." He straightened, and the blaze of his eyes held the yellow men, and the black, motionless.

Naomi, at the window behind him, gasped. "I know it looks tough," he encouraged her, "but you can make it. Don't look down. Go to the left.

_And keep clear of that wire._"

"I'm all right, Allan. But you--"

"Never mind about me. Go ahead."

Jung Sin jerked forward, driven by the madness that twisted his face into gargoyle hideousness. But Allan's ray-gun stabbed at him, and he halted.

"I'm out, Allan."
