"Officer of the watch. Take these prisoners to the locks. Kill them and put them out."
"I obey!" The officer, squat, with enormous torso, pointed a small wand, pointed with a tiny spot of that peculiar pulsating pink light, threateningly. Stolidly he herded them through a broad corridor. Now and then they passed inhabitants of this submarine city, nightmarish, pitiable creatures, now disturbed, dreading death. Sine wondered vaguely that they should cling to such an unhappy existence.
He was recalled to their own predicament when a metal gate, closed by a screw-wheel, loomed up in the poor light. The inside lock! The guard motioned them ahead, stood between them and the passage. He fumbled at his belt, ignoring the dull hammerblows of explosions transmitted by the water. He seized Kass by the throat, prepared to plunge the knife into his body.
Sine leaped past, crooked his arm around the man's thick neck, attempted to break his neck. But a giant arm threw him off easily. He fell to the floor. Like an echo came the concussion of another explosion.
The guard, without trace of ill-humor, turned his attention to Sine. He pointed the little wand at him, and the light glowed brighter. Sine felt again that torturing paralysis. His senses were leaving him. The pink light was throbbing, expanding....
He wondered why the stones of the passage should be pushing in, spurting water. The pink light faded. Tepid water struck him, stinging like needles. There was a roaring, blackness. A fat arm hooked around his waist—Lents', no doubt. He felt himself borne along in a swirl of water, strangling, fighting blindly. There was another terrific explosion shock, an interminable climbing struggle. Then his head broke water and he breathed air again. Lents came up beside him, puffing and blowing, and after a long wait—so long that they despaired, Kass came weakly to the surface.
CHAPTER V
The Struggle for Freedom
They were afloat, and comparatively safe from the rockets which shrieked out of the leaden sky and threw spectral waterspouts up into the fog before they exploded. Unless one exploded directly under them, or very near, they would be safe—for the time being.
