Pinario helped him out of the cowboy suit, saying, "It's as unwholesome a toy as you could want. A short period with it on, and the child would be unable to face contemporary reality. Look at you."

Standing with difficulty, Wiseman inspected the suit; Pinario had forcibly taken it from him.

"Not bad," he said in a trembling voice. "It obviously stimulates the withdrawal tendencies already present. I know I've always had a latent retreat fantasy toward my childhood. That particular period, when we lived in the country."

"Notice how you incorporated real elements into it," Pinario said, "to keep the fantasy going as long as possible. If you'd had time, you would have figured a way of incorporating the lab wall into it, possibly as the side of a barn."

Wiseman admitted, "I – already had started to see the old dairy building, where the farmers brought their market milk."

"In time," Pinario said, "it would have been next to impossible to get you out of it."

To himself, Wiseman thought, If it could do that to an adult, just imagine the effect on a child.

"That other thing you have there," Pinario said, "that game, it's a screwball notion. You feel like looking at it now? It can wait."

"I'm okay," Wiseman said. He picked up the third item and began to open it.

"A lot like the old game of Monopoly," Pinario said. "It's called Syndrome."

The game consisted of a board, plus play money, dice, pieces to represent the players. And stock certificates.

"You acquire stock," Pinario said, "same as in all this kind, obviously." He didn't even bother to look at the instructions. "Let's get Fowler down here and play a hand; it takes at least three."

Shortly, they had the Division Director with them. The three men seated themselves at a table, the game of Syndrome in the center.

"Each player starts out equal with the others," Pinario explained, "same as all this type, and during the play, their statuses change according to the worth of the stock they acquire in various economic syndromes."

The syndromes were represented by small, bright plastic objects, much like the archaic hotels and houses of Monopoly.

They threw the dice, moved their counters along the board, bid for and acquired property, paid fines, collected fines, went to the "decontamination chamber" for a period. Meanwhile, behind them, the seven model soldiers crept up on the citadel again and again.

"I'm tired of that," the child-dummy said. "Do something else."

The soldiers regrouped. Once more they started out, getting nearer and nearer the citadel.

Restless and irritable, Wiseman said, "I wonder how long that damn thing has to go on before we find out what it's for."

"No telling." Pinario eyed a purple-and-gold share of stock that Fowler had acquired. "I can use that," he said. "That's a heavy uranium mine stock on Pluto. What do you want for it?"

"Valuable property," Fowler murmured, consulting his other stocks. "I might make a trade, though."

How can I concentrate on a game, Wiseman asked himself, when that thing is getting closer and nearer to – God knows what? To whatever it was built to reach. Its critical mass, he thought.

"Just a second," he said in a slow, careful voice. He put down his hand of stocks. "Could that citadel be a pile?"

"Pile of what?" Fowler asked, concerned with his hand.

Wiseman said loudly, "Forget this game."

"An interesting idea," Pinario said, also putting down his hand. "It's constructing itself into an atomic bomb, piece by piece. Adding until -" He broke off. "No, we thought of that. There're no heavy elements present in it. It's simply a five-year battery, plus a number of small machines controlled by instructions broadcast from the battery itself. You can't make an atomic pile out of that."

"In my opinion," Wiseman said, "we'd be safer getting it out of here." His experience with the cowboy suit had given him a great deal more respect for the Ganymedean artificers. And if the suit was the benign one…

Fowler, looking past his shoulder, said, "There are only six soldiers now." Both Wiseman and Pinario got up instantly. Fowler was right. Only half of the set of soldiers remained. One more had reached the citadel and been incorporated.

"Let's get a bomb expert from the Military Services in here," Wiseman said, "and let him check it. This is out of our department." He turned to his boss, Fowler. "Don't you agree?"

Fowler said, "Let's finish this game first."

"Why?"

"Because we want to be certain about it," Fowler said. But his rapt interest showed that he had gotten emotionally involved and wanted to play to the end of the game. "What will you give me for this share of Pluto stock? I'm open to offers."

He and Pinario negotiated a trade. The game continued for another hour. At last, all three of them could see that Fowler was gaining control of the various stocks. He had five mining syndromes, plus two plastics firms, an algae monopoly, and all seven of the retail trading syndromes. Due to his control of the stock, he had, as a byproduct, gotten most of the money.

"I'm out," Pinario said. All he had left were minor shares which controlled nothing. "Anybody want to buy these?"

With his last remaining money, Wiseman bid for the shares. He got them and resumed playing, this time against Fowler alone.

"It's clear that this game is a replica of typical interculture economic ventures," Wiseman said. "The retail trading syndromes are obviously Ganymedean holdings."

A flicker of excitement stirred in him; he had gotten a couple of good throws with the dice and was in a position to add a share to his meager holdings. "Children playing this would acquire a healthy attitude toward economic realities. It would prepare them for the adult world."

But a few minutes later, he landed on an enormous tract of Fowler holdings, and the fine wiped out his resources. He had to give up two shares of stock; the end was in sight.

Pinario, watching the soldiers advance toward the citadel, said, "You know, Leon, I'm inclined to agree with you. This thing may be one terminal of a bomb. A receiving station of some kind. When it's completely wired up, it might bring in a surge of power transmitted from Ganymede."

"Is such a thing possible?" Fowler asked, stacking his play money into different denominations

"Who knows what they can do?" Pinario said, wandering around with his hands in his pockets. "Are you almost finished playing?"

"Just about," Wiseman said.

"The reason I say that," Pinario said, "is that now there're only five soldiers. It's speeding up. It took a week for the first one, and only an hour for the seventh. I wouldn't be surprised if the rest go within the next two hours, all five of them."

"We're finished," Fowler said. He had acquired the last share of stock and the last dollar.

Wiseman arose from the table, leaving Fowler. "I'll call Military Services to check the citadel. About this game, though, it's nothing but a steal from our Terran game Monopoly."

"Possibly they don't realize that we have the game already," Fowler said, "under another name."

A stamp of admissibility was placed on the game of Syndrome and the importer was informed. In his office, Wiseman called Military Services and told them what he wanted.

"A bomb expert will be right over," the unhurried voice at the other end of the line said. "Probably you should leave the object alone until he arrives."

Feeling somewhat useless, Wiseman thanked the clerk and hung up. They had failed to dope out the soldiers-and-citadel war game; now it was out of their hands.

The bomb expert was a young man, with close-cropped hair, who smiled friendlily at them as he set down his equipment. He wore ordinary coveralls, with no protective devices.
