Looming over the great transparent dome hung the flaming disk of Jupiter, so oppressively near that it seemed about to crash onto the asteroid. Its rays poured in a ruddy flood over the settlement, clearly illuminating each detail; and comparatively close against the face of the mighty planet they could see the whitish globe of Satellite III. It offered the nearest haven. They might arrive famished, but in the power-equipped space-suits which Friday was lugging they should be able to span the gap. The Hawk nodded to the port-locks on the left. "That one," he snapped. "We'll have two chances, the _Scorpion_ and the port, but the port's safest; we could never get the whole ship underway and through the lock in time. To prevent pursuit, all we have to do is leave the lock open after us." They hastened along the roof of the wing that ran that way. As yet there was no outside pursuit; most of the settlement's guards seemed to have been concentrated in the attack on the laboratory. But Carse knew it would only be a matter of seconds before coolies would emerge from half a dozen different points. He was trying to figure out which points they were likely to be when there passed, perilously close, the spit of an orange ray. He glanced back, to see the first of the crowd which had broken into the laboratory come clambering up through the roof. Then, as a second shot sizzled by, they arrived at the end of the wing. * * * * * Friday took the fifteen-foot drop without hesitation. Carse lowered Leithgow to him and then swung down himself. They panted forward again, over grayish, glittering soil. Some three hundred yards of open space lay between them and the port-locks. Friday now led the way, weighted down under the heavy suits; the scientist came next and then the Hawk, his sole remaining gun replying at intervals to the ever-thickening barrage from behind. They had covered perhaps a half of that distance when the negro's steps suddenly faltered and he halted. "Look there!" he groaned. "Cuttin' us off! We'll never make it, suh!" Carse looked where he pointed, and saw a squad of half a dozen men emerging from a building well to their left. They were running at full speed for the lock, and, as Friday had said, it was obvious that they would get there first. He glanced quickly around. Pursuit from the laboratory in the rear was hot--and moreover three coolies were angling sharply out on each side, to outflank them! In a minute they would be surrounded! Unable to reach either the port or the ship! And then came the crowning piece of ill-luck. Suddenly the Hawk winced; staggered; clapped a hand to his shoulder. A lucky shot from an enemy gun had caught him. "You're hit!" cried Leithgow. "It's nothing...." * * * * * The slender adventurer stood very still, thinking. He was trapped. But he was never more dangerous than when he was trapped.
