They worked hurriedly, between jumps fore and aft. Chafi Three, while they were still in the control cubicle, threw the ship out of hyperdrive within scant miles of the neighboring sun's single planet. Chafi Four, on the next jump, scanned the ship's charts and identified the system through which they traveled.

Luck was with them. The system had been catalogued some four Ciriimian generations before and tagged: Planet undeveloped. Tranquil marine intelligences only.

The discovery relieved them greatly for the reason that no Ciriimian, even to save his own feathered skin, would have set down such a monster as the Zid among rational but vulnerable entities.

The planet was a water world, bare of continents and only sparsely sprinkled with minor archipelagoes. The islands suited the Chafis' purpose admirably.

"The Zid does not swim," Chafi Four radiated. "Marooned, it can do no harm to marine intelligences."

"Also," Chafi Three pointed out as they dodged to the control cubicle again just ahead of the slavering Zid, "we may return later with a Canthorian hunting party and recover our investment."

Closing their perception against the Zid's distracting ragings, they set to work with perfect coordination.

Chafi Three set down the ship on an island that was only one of a freckling chain of similar islands. Chafi Four projected himself first to the opened port; then, when the Zid charged after him, to the herbivore-cropped sward of tropical setting outside.

The Zid lunged out. Chafi Four teleported inside again. Chafi Three closed the port. Together they relaxed their perception shields in relief—
