Earth had been an easy target because of innocent radiation of energy into space, its baby-bird cheeping in the unprotected tree branch of the solar system.

Martin felt a weary sadness, an echo of all the sadness he had known since Earth's death. Was there ever a point in the scale of galactic civilizations when strangers could trust each other? Did civilizations ever develop sufficient scruples that not one of them would think of creating machines of mass destruction?

Perhaps; but humans were certainly not on that level.

Martin's reading of human history easily led him to imagine planet-destroying probes created by his people, and turned against others. And if hecould imagine it, the moms could imagine it as well.

What sort of equality could exist between children and Benefactors under those circumstances?

Martin waited in the empty schoolroom, uneasy, a tic in his left eye, simple nerves. He stood near the sphere. The stars appeared normal now, and the sphere was offering an unaltered view in the direction of Wormwood, which he could make out even without help as a slightly brighter spot of light among the myriads. Brighter still was the red burn of Behemoth. Leviathan was not visible from this angle.

The War Mother entered.

"Hello, Martin," it said. "How are the children?"

"Fine, physically. A few social problems. Some aren't meshing perfectly." He always seemed to optimize the situation, making it sound better than he actually thought it was. Was this part of what Ariel might have called toadyingto the moms?

"Have you developed plans for further training?"

He swallowed. "No," he said. "We feel stymied."

"Why?"

"We can't do the Job without knowing what might be waiting for us down there."

"All the information you need is being provided as we receive it."

"I mean background," Martin said. "Information about other civilizations, other incidents—how the strategies were created, how we can adapt them to suit our needs… I mean, to adapt them, we have to…" He swallowed again. For a Pan, he was not showing much fortitude. "You have to trust us with all your information. We're calling for full disclosure."

To Martin's surprise and concern, the War Mother did not speak for several long seconds. "The information provided should be adequate," it finally answered.

"We're being asked to show independent thought, to devise our own strategies… and the libraries aren't detailed. How did others fight against the planet-wreckers? How did yourbuilders fight them?"

More seconds of silence. Surely it did not need so much time to compute or think of an answer.

"Your requests cannot be met," the War Mother said. "The information you require is dangerous."

Martin was astonished by the word "dangerous." That doesn't make sense," he said.

"Cooperation was required to build the Ships of the Law. To encourage the cooperation of many civilizations and beings, certain precautions were necessary, among them, that security would be maintained. Ships of the Law might be captured, and their information used to seek out and harm those who built the ships."

Martin had never thought of being captured;it had seemed, from the very beginning, that at least the children were safe, traveling in a Ship of the Law, the ultimate power, the belated victor of the war that had destroyed Earth. But of course that was not a war— just a battle. Probably an unimportant battle, at that.

Martin was not about to budge. "We need to have all your information shared with us."

"Surely you hope to survive this mission," the War Mother said.

"Of course."

"Martin, if your brothers and sisters survive, you, too, could be dangerous. If you are given such information, you also might seek the builders of these instruments."

Martin swallowed hard. "We cannot create strategies out of nothing. I've asked questions that needto be answered, and received no answers."

"You have worked with the best information available. There are simply no clues to where the Benefactors might be found. The information you need is available. Use it."

"I've been told—"

"You are Pan," the mom said.

He swallowed harder, and his tongue seemed to grow thick. "We'll stand down."

"What is 'stand down'?" the mom asked.

"We'll refuse to enact the Law."

"If that is your choice, the ship will change from its present course."

Martin relaxed his clenched fists. He was not angry with the moms; he was not angry with the children. With regard to himself he felt nothing. He looked away from the copper-bronze robot, seeing too clearly how naive they all were.

"We're just asking to be trusted," Martin said, working to keep his voice level.

"We are not empowered to trust or not to trust. Nor can we give you information that this ship does not carry. We cannot do the impossible, Martin."

He felt ill and exhausted. Why had he let the children put him up to this? Because he was Pan, and represented them? That didn't seem at all sufficient to explain his predicament and his misery.

"Why were we sent on this mission when we don't have the information we need to complete it?" He sounded petulant and petty, and he hated it.

"What you lack is information that our builders think you will not need."

Martin's mind worked furiously to find a chink in this thick armor of logic. I would have designed the ship the same way! We all would have!

"But the ship carries information about Earth. If it's captured, they could—the Killers could—"

"This Job would be impossible if you did not have access to your culture, your history and planetary memories."

"You'd risk our solar system, but you will not risk your… makers? Your planet, or planets?"

"That is the way it must be."

Another wall, huge and unyielding; two walls actually, closing with him between. "We feel inadequate to do the Job," he said softly, eyes turned away.

"Go back to the others and tell them they are not inadequate. They have the resources they need.

"There is, in this ship, something that goes beyond knowledge, that is hidden in its structure and the way it operates, which allows this ship to judge with high accuracy the chances of a mission's success. Call it a mechanical instinct. Your people are very capable. Tell them."

Martin lifted his head and stepped back. "I'll try," he said.

His face was red as he left the schoolroom. He had been maneuvered into presenting a case without believing it himself. That showed his weakness as a leader. Failing to get what he had been sent to get would make him seem weak in the eyes of some children—Ariel in particular. But he did not care what she thought.

What would Theresa think? And William?

What would Rosa Sequoia think? Rosa, who needed a strong leader to draw her back into the group?

Sitting on the edge of a table, Martin finished his crew report, the most difficult few minutes in recent memory. Most of the children—seventy-two of them—sat in the main cafeteria, the only space besides the schoolroom large enough to hold them all at once.

The ship's deceleration had hastened and they now faced a steady two g's. They were tired and they listened to his report quietly.

"That's it," he concluded, looking from face to face to keep direct visual contact with as many as he could. Then he gave that up; it might make him seem nervous. Instead, he focused on four or five in the front ranks.
