sually, when pursuing an enemy, Hawk Carse was impassive and grim, apparently emotionless, icy. But now he seemed somehow disturbed.

He fidgeted around, glancing occasionally at the visi-screen to make sure his quarry was not changing course, now watching Friday juggle through the skin of atmosphere into outer space, and now standing apart, silent and solitary, brooding.

There was something about the affair he didn't like. Something that was deeply hidden, that could not be grasped clearly; that might, on the other hand, be pure imagination. And yet, why—

Why, for instance, had the brigands taken to their heels with just the barest semblance of fight? Why, with their defensive ray-web proof for some time at least against his offensive rays, had they left without more of a struggle for the horn? Why were they so willing to flee, knowing as they must that he, the Hawk, would follow? Did they not know he had—thanks to Master Scientist Eliot Leithgow—the fastest ship in space, and would inevitably overtake them?

Were they Ku Sui's men? It seemed so, certainly, from the great strength of their defensive ray-web. No other ships that he knew of in space save Ku Sui's possessed such power. But—it wasn't the brilliant Eurasian's customary style. It was too simple for him.

Inside, light and color, life and action; outside, the eternal, sable void, sprinkled with its millions of sparkling motes of worlds. And ahead—shown now on the visa-screen only by the light dots of its ports—was the brigand craft.

The Star Devil was smoothly building up the speed that would eventually bring her up to the craft of the enemy. Carse's Earth-watch told him that an hour and a half had passed. A vague anxiety oppressed him, but he shook it off with the thought that soon the time for accounting would arrive. Only forty minutes more; probably less. His fears—foolish. He was getting too suspicious....
