In utter darkness the glint of metal often seemed to draw the eyes like a magnet, to make itself known even without illumination. But there seemed to be a faint glow far off somewhere. He couldn't be sure, but light there should have been if--as he more than half-suspected--he was in one of the ship's below-deck ballast or storage compartments. The deck beneath his feet was straight and level and cluttered with no impediments. He moved forward warily, testing every step until a wall of metal stopped him. He halted abruptly, felt along the barrier and became aware that it was studded with small bolts and was just a little corrugated. Exhibit A: one supporting metal beam, rough and slightly uneven in texture. Abruptly he reached the end of it and found himself underway again, still moving cautiously to avoid unseen pitfalls. He had not progressed more than a dozen feet when he heard the scrape of footsteps other than his own, and someone moved up close to him and blocked his way in the darkness. For an instant the wild thought went through his mind that the someone was the captain. But he had seen and talked with the Captain and that self-contained, blunt-spoken man wasn't nearly as big physically as the path-blocker seemed to be. The someone did not speak. But Corriston could sense the enmity flowing from him, the utter refusal to budge an inch, the determination to make his nearness a deadly threat in itself. Then the someone moved back a step. The far-off light could hardly have been an illusion, because for the barest instant Corriston could dimly make out the huge bulk of the man and the glint of the knife in his hand. Two big men in the space of half an hour! The first had ceased to draw breath and the second was his killer. Corriston was suddenly sure of it. He knew it instinctively. Then began the struggle which had almost robbed Corriston of his life, the cruel, one-sided, impossible-to-win struggle in total darkness. And Corriston had won it. * * * * * Now almost in disbelief, Corriston looked down at the knife he had taken from the loser, telling himself that it was impossible that so much could have happened in so short a time and that he could still be alive at the end of it. The wound in his shoulder was no longer painless, but it had ceased to bleed profusely, and his exploring fingers convinced him that the knife had severed no more than a superficial ligament. He strained his ears in the sudden quiet, listening for a possible return of his adversary. He did not think that the defeated man would attempt a second attack. But there was no telling what he might or might not do. Probably he'd ascended the companionway by now and was mingling with the other passengers.
