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 modicum 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 clustered about those two, and a third, a skew-eyed Oriental, intent on some game they were playing with little sticks that passed from hand to hand.
