"Of course livestock," General Mozart said unsympathetically, as if Rae were some sort of idiot.

The third steer driven aboard the UN transport carried a harness at its neck; the UN military policeman at the entrance hatch spotted it, shot the steer at once, summoned Hoagland to dispose of the carcass.

Squatting by the dead steer, Hoagland Rae examined the harness and its wiring. As with the m-gopher, the harness connected, by delicate leads, the brain of the animal to the sentient organism – whatever it was – which had installed the apparatus, located, he assumed, no farther than a mile from the settlement. What was this animal supposed to do? he wondered as he disconnected the harness. Gore one of us? Or – eavesdrop. More likely that; the transmitter within the harness hummed audibly; it was perpetually on, picking up all sounds in the vicinity. So they know we've brought in the military, Hoagland realized. And that we've detected two of these constructs, now.

He had a deep intuition that this meant the abolition of the settlement. This area would soon be a battleground between the UN military and the – whatever they were. Falling Star Entertainment Enterprises. He wondered where they were from. Outside the Sol System, evidently.

Kneeling momentarily beside him a blackjack – a black-clad UN secret police officer – said, "Cheer up. This tipped their hand; we could never prove those carnivals were hostile, before. Because of you they never made it to Terra. You'll be reinforced; don't give up." He grinned at Hoagland, then hurried off, disappearing into the darkness, where a UN tank sat parked.

Yes, Hoagland thought. We did the authorities a favor. And they'll reward us by moving massively into this area.

He had a feeling that the settlement would never be quite the same again, no matter what the authorities did. Because, if nothing else, the settlement had failed to solve its own problems; it had been forced to call for outside help. For the big boys.

Tony Costner gave him a hand with the dead steer; together they dragged it to one side, gasping for breath as they grappled with the still warm body. "I feel responsible," Tony said, when they had set it down.

"Don't." Hoagland shook his head. "And tell your boy not to feel bad."

"I haven't seen Fred since this first came out," Tony said miserably. "He took off, terribly disturbed. I guess the UN MPs will find him; they're on the outskirts rounding everybody up." He sounded numb, as if he could not quite take in what was happening. "An MP told me that by morning we could come back. The arsine gas would have taken care of everything. You think they've run into this before? They're not saying but they seem so efficient. They seem so sure of what they're doing."

"Lord knows," Hoagland said. He lit a genuine Earth-made Optimo cigar and smoked in glum silence, watching a flock of black-face sheep being driven into the transport. Who would have thought the legendary, classic invasion of Earth would take this form? he asked himself. Starting here at our meager settlement, in terms of small wired figurines, a little over a dozen in all, which we labored to win from Falling Star Entertainment Enterprises; as General Mozart said, the invaders didn't even want to give them up. Ironic.

Bob Turk, coming up beside him, said quietly, "You realize we're going to be sacrificed. That's obvious. Arsine will kill all the gophers and rats but it won't kill the microrobs because they don't breathe. The UN will have to keep blackjack squads operating in this region for weeks, maybe months. This gas attack is just the beginning." He turned accusingly to Tony Costner. "If your kid -"

"All right," Hoagland said in a sharp voice. "That's enough. If I hadn't taken that one apart, closed the circuit – you can blame me, Turk; in fact I'll be glad to resign. You can run the settlement without me."

Through a battery-driven loudspeaker a vast UN voice boomed, "All persons within sound of my voice prepare to board! This area will be flooded with poisonous gas at 14:00. I repeat -" It repeated, as the loudspeakers turned in first one direction and then another; the noise echoed in the night darkness.

Stumbling, Fred Costner made his way over the unfamiliar, rough terrain, wheezing in sorrow and weariness; he paid no attention to his location, made no effort to see where he was going. All he wanted to do was get away. He had destroyed the settlement and everyone from Hoagland Rae on down knew it. Because of him -

Far away, behind him, an amplified voice boomed, "All persons within sound of my voice prepare to board! This area will be flooded with poisonous gas at 14:00. I repeat, all persons within sound of my voice -" It dinned on and on. Fred continued to stumble along, trying to shut out the racket of the voice, hurrying away from it.

The night smelled of spiders and dry weeds; he sensed the desolation of the landscape around him. Already he was beyond the final perimeter of cultivation; he had left the settlement's fields and now he stumbled over unplowed ground where no fences or even surveyor's stakes existed. But they would probably flood this area, too, however; the UN ships would coast back and forth, spraying the arsine gas, and then after that special forces troops would come in, wearing gas-masks, carrying flame throwers, with metal-sensitive detectors on their backs, to roust out the fifteen microrobs which had taken refuge underground in the burrows of rats and vermin. Where they belong, Fred Costner said to himself. And to think I wanted them for the settlement; I thought, because the carnival wanted to keep them, that they must be valuable.

He wondered, dimly, if there was any way he could undo what he had done. Find the fifteen microrobs, plus the activated one which had almost killed Hoagland Rae? And – he had to laugh; it was absurd. Even if he found their hideout – assuming that all of them had taken refuge together in one spot – how could he destroy them? And they were armed. Hoagland Rae had barely escaped, and that had been from one acting alone.

A light glowed ahead.

In the darkness he could not make out the shapes which moved at the edge of the light; he halted, waited, trying to orient himself. Persons came and went and he heard the voices, muted, both men's and women's. And the sound of machinery in motion. The UN would not be sending out women, he realized. This was not the authorities.

A portion of the sky, the stars and faint nocturnal swath of haze, had been blotted out, and he realized all at once that he was seeing the outline of a large stationary object.

It could be a ship, parked on its tail, awaiting take-off; the shape seemed roughly that.

He seated himself, shivering in the cold of the Martian night, scowling in an attempt to trace the passage of the indistinct forms busy with their activity. Had the carnival returned? Was this once more the Falling Star Entertainment Enterprises vehicle? Eerily, the thought came to him: the booths and banners and tents and platforms, the magic shows and girl platforms and freaks and games of chance were being erected here in the middle of the night, in this barren area lost in the emptiness between settlements. A hollow enactment of the festivity of the carny life, for no one to see or experience. Except – by chance – himself. And to him it was revolting; he had seen all he wanted of the carnival, its people and – things.

Something ran across his foot.

With his psycho-kinetic faculty he snared it, drew it back; reaching, he grabbed with both hands until all at once he had snatched out of the darkness a thrashing, hard shape. He held it, and saw with fright one of the microrobs; it struggled to escape and yet, reflexively, he held onto it. The microrob had been scurrying toward the parked ship, and he thought, the ship's picking them up. So they won't be found by the UN. They're getting away; then the carnival can go on with its plans.
