ilence rested tensely over the two men, to be broken at last by the clump of feet proceeding aft on the deck above.

Carse switched off the light. His voice was but faintly audible.

"Coming down to clean off the dust. He'll have a flash. Hide behind the truss-work at your side, and when he gets here seize him by the neck. I'll be with you right away. I want no noise."

Friday saw a great light, and grinned in the confidence it brought him. Of course! That explained the rope. The plan was so simple it had escaped him. Already he felt cheerful. It was only mental worries, and never physical hazards, that unsettled him. He angled around the truss-work and shrank into as small a space as possible—which wasn't very small, as he still wore his bulky, clumsy suit.

The clump-clump of feet had died: now there came the sound of the man-hole aft being raised. A white beam pronged down into the darkness, felt around and flicked off. Boots clanged on the connecting ladder; reached the bottom. The light appeared again, lower now, and came slowly forward. Limned faintly against the reflected light was the outline of a crouching man's body.

He went to hands and knees and progressed carefully, his flash darting to left and right. Suddenly, in a certain light, the two who awaited his coming saw a swarthy, black-stubbled face in profile. He wore no space-suit! That meant, Friday reflected, that the brigands had cleared the ship of the gas in some way. It meant that they could get out of their own suits.

But they could not possibly do so at the moment. They heard the nearby pirate's breathing, a harsh oath as he stubbed a toe. The negro tightened his giant arms and held himself ready, his eyes steady on the black outline which signified his quarry. Then the pirate was close enough.

It was over in seconds. Rounding the truss, Friday caught the man in the armored crook of his arm. A startled croak preluded the thump of two bodies on the hull; there was the tinkle of a falling hand-flash and a slight squirming which was quickly stopped by a belting punch.
