clicked together viciously. The Quedak moved out of the way and its barb-headed tail flashed out, fastening itself in the beast's back. The Quedak held on grimly while the beast leaped and squirmed. Setting his feet, the Quedak concentrated on the all-important task of pumping a tiny white crystal down the length of his tail and under the beast's skin. But this most important of the Quedak faculties was still dormant. Unable to accomplish anything, the Quedak released his barbs, and, taking careful aim, accurately drove his sting home between the black beast's eyes. The blow, as the Quedak had known, was lethal.

The sails billowed under powerful gusts of the northwest breeze, and the rusty Allison-Chambers diesel rumbled beneath a teak grating. The skipper and mate stood on the bridge deck and watched the reef approach. "Anything yet?" the skipper asked. He was a stocky, balding man with a perpetual frown on his face. He had been sailing his schooner among the uncharted shoals and reefs of the Southwest Pacific for twenty-five years. He frowned because his old ship was not insurable. His deck cargo, however, was insured. Some of it had come all the way from Ogdensville, that transshipment center in the desert where spaceships landed. "Not a thing," the mate said. He was watching the dazzling white wall of coral, looking for the gleam of blue that would reveal the narrow pass to the inner lagoon. This was his first trip to the Solomon Islands.
