It was a short scream, strangled with sea-water, but it set the hairs prickling on Fallon’s neck. He looked past the girl, outward. Something was rising out of the sea. * * * * * Webb Fallon, standing shoulder-deep in the cold water, stared in a temporary paralysis of shock. The thing simply couldn’t be. There was a snout armed with a wicked sword. That and the head behind it were recognizable as those of a swordfish. But the neck behind them was long and powerful, and set on sloping shoulders. Members like elongated fins just becoming legs churned the surface. A wholly piscine tail whipped up gouts of spray behind the malformed silver body. Fallon moved suddenly. He grabbed the girl and started toward shore. The Thing emitted a whistling grunt and surged after them. Waves struck them; the aftersuck pulled at their legs. They floundered, like dreamers caught in nightmare swamps. And Fallon, through the thrashing and the surf and the sea-water in his ears, began to hear other sounds. There was a vast stirring whisper, a waking and surging of things driven up and out. There were overtones of cries from unearthly throats. Presently, then, there were human screams. Fallon’s toes found firm sand. Still clutching the girl, he splashed through the shallows. He could hear the wallowing thunder of creatures behind them, and knew that they had to run. But he faltered, staring, and the girl made a little choked sound beside him. The shallow margin of the sea was churned to froth by a nightmare horde. The whole broad sweep of the beach was invaded by things that, in that stunned moment, Fallon saw only as confused shadows. He started to run, toward the hilly streets beyond the beach. The creature with the swordfish snout was almost on them. A fish, out of the sea! It reared its snaky neck and struck down. Fallon dodged convulsively. The sword flashed down and buried itself in the sand not five inches from his foot. It never came out of the sand. A tail-less, stub-legged thing with three rows of teeth in its shark-like jaws fastened onto the creature’s neck, and there was hot mammalian blood spilling out. They ran together, Fallon and the girl. The summer crowds filling the beaches, the promenade, the hot-dog stands and bath-houses, were fighting in blind panic up the narrow streets to the top of the bluff. It was useless to try to get through. Fallon made for an apartment house. Briefly, in clear, bright colors, he saw isolated scenes. A starfish twenty feet across wrapping itself around a woman and her stupefied child. A vast red crab pulling a man to bits with its claws. Something that might once have been an octopus walking on four spidery legs, its remaining tentacles plucking curiously at the volley-ball net that barred its way.
