were a part of me, like my hand. And then the machinery began to move, because—because I wanted it to. Maybe there was some fuel left, father, and maybe—" "Why are you afraid of the truth, Gill?" "People don't run machines by wanting them to go!" "The thinking mind, my son, is capable of—" Pendillo's voice trailed off, for they all heard the sound outside—the high whine made by the force-field of an enemy sphere. Lanny darted to the showroom window. At the end of the street an opalescent sphere was riding in the fog, three feet above the ground. Enemy police guards in protective capsules spilled through the open port, carrying energy guns slung over their shoulders. "The Almost-men picked up the sound of the motor," Pendillo gasped. Then he saw the woman in the white uniform of the Triangle. She stood at the port, spotlighted by the glow of blue light that came from within the ship. It was the missionary, Tak Laleen. In the street the tracer light began to dart back and forth over the empty buildings, responding to the commands of the sound receptors. Lanny and Gill seized their father and plunged into the choking darkness of the forest. Dead brush snapped.

Lying flat against the cold earth, they wormed their way foot by foot toward the coast. Behind them they saw the force-field capsules of six enemy guards floating above the trees.
