Philip Dick - The Complete Stories of Philip K. Dick Vol. 5 - The Eye of the Sibyl and Other Classic Stories

"Looks like a Roman catapult," Tinbane said. "But with a vertical rather than a horizontal axis."

"That's our reaction, too. And look at the sling. In terms of the scale of the village it's inordinately large. Immense, in fact; specifically, it's not to scale ."

"It looks as if it would almost hold -"

"Not almost," the technician said. "We measured it. The size of the sling is exact; one of those steel balls would fit perfectly into it."

"And then?" Tinbane said, feeling chill.

"And then it would hurl the ball back at the player," the lab technician said calmly. "It's aimed directly toward the front of the machine, front and upward." He added, "And it's been virtually completed."

The best defense, Tinbane thought to himself as he studied the out-spacers' illegal pinball machine, is offense. But whoever heard of it in this context?

Zero, he realized, isn't a low enough score to suit the defensive circuitry of the thing. Zero won't do. It's got to strive for less than zero. Why? Because, he decided, it's not really moving toward zero as a limit; it's moving, instead, toward the best defensive pattern. It's too well designed. Or is it?

"You think," he asked the lean, tall lab technician, "that the outspacers intended this?"

"That doesn't matter. At least not from the immediate stand-point. What matters is two factors: the machine was exported – in violation of Terran law – to Terra, and it's been played by Terrans. Intentionally or not, this could be, in fact will soon be, a lethal weapon." He added, "We calculate within the next twenty games. Every time a coin is inserted, the building resumes. Whether a ball gets near the village or not. All it requires is a flow of power from the device's central helium battery. And that's automatic, once play begins." He added, "It's at work building the catapult right now, as we stand here. You better release the remaining four balls, so it'll shut itself off. Or give us permission to dismantle it – to at least take the power supply out of the circuit."

"The outspacers don't have a very high regard for human life," Tinbane reflected. He was thinking of the carnage created by the ship taking off. And that, for them, was routine. But in view of that wholesale destruction of human life, this seemed unnecessary. What more did this accomplish?

Pondering, he said, "This is selective. This would eliminate only the gameplayer."

The technician said, "This would eliminate every gameplayer. One after another."

"But who would play the thing," Tinbane said, "after the first fatality?"

"People go there knowing that if there's a raid the outspacers will burn up everyone and everything," the technician pointed out. "The urge to gamble is an addictive compulsion; a certain type of person gambles no matter what the risk is. You ever hear of Russian Roulette?"

Tinbane released the second steel ball, watched it bounce and wander toward the replica village. This one managed to pass through the rough terrain; it approached the first house comprising the village proper. Maybe I'll get it, he thought savagely. Before it gets me. A strange, novel excitement filled him as he watched the ball thud against the tiny house, flatten the structure and roll on. The ball, although small to him, towered over every building, every structure, that made up the village.

– Every structure except the central catapult. He watched avidly as the ball moved dangerously close to the catapult, then, deflected by a major public building, rolled on and disappeared into the take-up slot. Immediately he sent the third ball hurtling up its channel.

"The stakes," the technician said softly, "are high, aren't they? Your life against its. Must be exceptionally appealing to someone with the right kind of temperament."

"I think," Tinbane said, "I can get the catapult before it's in action."

"Maybe. Maybe not."

"I'm getting the ball closer to it each time."

The technician said, "For the catapult to work, it requires one of the steel balls; that's its load. You're making it increasingly likely that it'll acquire use of one of the balls. You're actually helping it." He added somberly, "In fact it can't function without you; the gameplayer is not only the enemy, he's also essential. Better quit, Tinbane. The thing is using you."

"I'll quit," Tinbane said, "when I've gotten the catapult."

"You're damn right you will. You'll be dead." He eyed Tinbane narrowly. "Possibly this is why the outspacers built it. To get back at us for our raids. This very likely is what it's for."

"Got another quarter?" Tinbane said.

In the middle of his tenth game a surprising, unexpected alteration in the machine's strategy manifested itself. All at once it ceased routing the steel balls entirely to one side, away from the replica village.

Watching, Tinbane saw the steel ball roll directly – for the first time – through the center. Straight toward the proportionally massive catapult.

Obviously the catapult had been completed.

"I outrank you, Tinbane," the lab technician said tautly. "And I'm ordering you to quit playing."

"Any order from you to me," Tinbane said, "has to be in writing and has to be approved by someone in the department at inspector level." But, reluctantly, he halted play. "I can get it," he said reflectively, "but not standing here. I have to be away, far enough back so that it can't pick me off." So it can't distinguish me and aim, he realized.

Already he had noted it swivel slightly. Through some lens-system it had detected him. Or possibly it was thermotropic, had sensed him by his body heat.

If the latter, then defensive action for him would be relatively simple: a resistance coil suspended at another locus. On the other hand it might be utilizing a cephalic index of some sort, recording all nearby brain-emanations. But the police lab would know that already.

"What's its tropism?" he asked.

The technician said, "That assembly hadn't been built up, at the time we inspected it. It's undoubtedly coming into existence now, in concert with the completion of the weapon."

Tinbane said thougtfully, "I hope it doesn't possess equipment to record a cephalic index." Because, he thought, if it did, storing the pattern would be no trouble at all. It could retain a memory of its adversary for use in the event of future encounters.

Something about that notion frightened him – over and above the immediate menace of the situation.

"I'll make a deal," the technician said. "You continue to operate it until it fires its initial shot at you. Then step aside and let us tear it down. We need to know its tropism; this may turn up again in a more complex fashion. You agree? You'll be taking a calculated risk, but I believe its initial shot will be aimed with the idea of use as feedback; it'll correct for a second shot… which will never take place."

Should he tell the technician his fear?

"What bothers me," he said, "is the possibility that it'll retain a specific memory of me. For future purposes."

"What future purposes? It'll be completely torn down. As soon as it fires."

Reluctantly, Tinbane said, "I think I'd better make the deal." I may already have gone too far, he thought. You may have been right.

The next steel ball missed the catapult by only a matter of a fraction of an inch. But what unnerved him was not the closeness; it was the quick, subtle attempt on the part of the catapult to snare the ball as it passed. A motion so rapid that he might easily have overlooked it.

"It wants the ball," the technician observed. "It wants you ." He, too, had seen.

With hesitation, Tinbane touched the plunger which would release the next – and for him possibly the last – steel ball.

"Back out," the technician advised nervously. "Forget the deal; stop playing. We'll tear it down as it is."
