But Raf had seen enough to freeze him where he was for a moment. The creature which had popped out of the ground only to be struck by the box and knocked into the river--he would take oath on the fact that it was not one of the furred animals he had seen on the sea island. Surely it had been smooth-skinned, not unlike the aliens in conformation--one of their own kind they had been hunting down, a criminal or a rebel? Puzzled, the pilot moved along from roof to roof, trying to pick up the trail of the party in the boat, but as far as he could now see, the river was bare. If they had come ashore anywhere along here, they had simply melted into the city. At last he was forced to use the homing beam, and it guided him back across the deserted metropolis to the field. There was still activity about the globe; they were bringing in the loot from the warehouse, but Lablet and Hobart stood by the flitter. As the pilot came up to them, the captain looked up eagerly. "What happened?" Raf sensed that there had been some change during his absence, that Hobart was looking to him for an explanation to make clear happenings here. He told his story of the hunt and its ending, the capture of the stranger. Lablet nodded as he finished. "That is the reason for this, you may depend upon it, Captain. One of their own people is at the bottom of it." "Of what?" Raf wanted to ask, but Soriki did it for him. Hobart smiled grimly. "We are all traveling back together. Take off in the early morning. For some reason they wanted us out of the globe in a hurry--practically shoved us out half an hour ago." Though the Terrans kept a watch on the larger ship as long as the light lasted, the darkness defeated them. They did not see the prisoner being taken aboard. Yet none of them doubted that sometime during the dusky hours it had been done. It was barely dawn when the globe took off the next day, and Raf brought the flitter up on its trail, heading westward into the sea wind. Below them the land held no signs of life. They swept over the deserted, terraced city that was the gateway to the guarded interior, flew back over the line of sea islands. Raf climbed higher, not caring to go too near the island where the aliens had wrought their terrible vengeance on the trip out. And all four of the Terrans knew relief, though they might not admit it to each other, when once more Soriki was able to establish contact with the distant spacer. "Turn north, sir?" the pilot suggested. "I could ride her beam in from here--we don't have to follow them home." He wanted to do that so badly it was almost a compulsion to make his hand move on the controls. And when Hobart did not answer at once, he was sure that the captain would give that very order, taking them out of the company of those he had never trusted. But Lablet spoiled that. "We have their word, Captain. That anti-grav unit that they showed us last night alone--"
