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 space 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 scum 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.
