Voices. They were not loud, but there was no attempt at secrecy. There were footsteps, the sounds of branches snap-ping. In Naismith's fast-dimming display, Wili could see at least five pairs of feet. They walked past a bent and twisted tree he remembered just two hundred meters back. Wili strained his ears to make sense of their words, but it was neither English nor Spanish. Jeremy muttered, "Russian, after all!"
Finally, the enemy came over the ridge that marked the far end of the ravine. Unsurprisingly, they were not in a single file now. Wili counted ten figures strung out against the starry sky. Almost as a man, the group froze, then dove for cover with their guns firing full automatic. The three on the bobble hugged the dirt as rounds whizzed by, thunking into the trees. Ricochets off the bobble sounded like heavy hail on a roof. Wili kept his face stuck firmly in the moist bed of forest needles and wondered how long the three of them could last.

"Gentlemen of the Peace Authority, Greater Tucson has been destroyed." The New Mexico Air Force general slapped his riding crop against the topographical map by way of emphasis. A neat red disk had been laid over the downtown district, and paler pink showed the fallout footprint. It all looked very precise, though Hamilton Avery. suspected it was more show than fact. The government in Al- buquerque had communication equipment nearly on a par with the Peace, but it would take aircraft or satellite recon to get a detailed report on one of their western cities this quick-ly: The detonation had happened less than ten hours earlier.
The general -Avery couldn't see his name tag, and it probably didn't matter anyway - continued, "That's three thousand men, women, and children immediately dead, and God knows how many hundreds to die of radiation poison-ing in the months to come." He glared across the conference table at Avery and the assistants he'd brought to give his delegation the properly important image.
For a moment it seemed as though the officer had finished speaking, but in fact he was just catching his breath. Hamil-ton Avery settled back and let the blast roll over him. "You of the Peace Authority deny us aircraft, tanks. You have weakened what is left of the nation that spawned you until we must use force simply to protect our borders from states that were once friendly. But what have you given us in return?" The man's face was getting red. The implication had been there, but the fool insisted on spelling it out: If the Peace Authority couldn't protect the Republic from nuclear weapons, then it could scarcely be the organization it adver-tised itself to be. And the general claimed the Tucson blast was incontrovertible proof that some nation possessed nukes and was using them, despite the Authority and all its satel-lites and aircraft and bobble generators.
On the Republic's side of the table, a few heads nodded agreement, but those individuals were far too cautious to say aloud what their scapegoat was shouting to the four walls. Hamilton pretended to listen; best to let this fellow hang himself. Avery's subordinates followed his lead, though for some it was an effort. After three generations of undisputed rule, many Authority people took their power to be God-given. Hamilton knew better.
He studied those seated around the general. Several were Army generals, one just back from the Colorado. The others were civilians. Hamilton knew this group. In the early years, he had thought the Republic of New Mexico was the greatest threat to the Peace in North America, and he had watched them accordingly. This was the Strategic Studies Committee. It ranked higher in the New Mexico government than the
Group of Forty or the National Security Council - and of course, higher than the cabinet. Every generation, governments seemed to breed a new inner circle out of the older, which was then used as a sop to satisfy larger numbers of less influential people. These men, together with the President, were the real power in the Republic. Their "strategic studies" extended from the Colorado to the Mississippi. New Mexico was a powerful nation. They could invent the bobble and nuclear weapons all over again if they were allowed.
They were easy to frighten nonetheless. This Air Force general couldn't be a full-fledged member of the group. The NMAF manned a few hot-air balloons and dreamed of the good old days. The closest they ever got to modern aircraft was a courtesy flight on an Authority plane. He was here to say things their government wanted said but did not have the courage to spit out directly.
The old officer finally ran down, and sat down. Hamilton gathered his papers and moved to the podium. He looked mildly across at the New Mexico officials and let the silence lengthen to significance.
It was probably a mistake to come here in person. Talking to national governments was normally done by officers two levels below him in the Peace Authority. Appearing in person could easily give these people an idea of the true importance of the incident. Nevertheless, he had wanted to see these men close up. There was an outside chance they were involved in the menace to the Peace he had discovered the last few months.
Finally he began. "Thank you, General, uh, Halberstamm. We understand your anxiety, but wish to emphasize the Peace Authority's long-standing promise. No nuclear weapon has exploded in nearly fifty years and none exploded yesterday in Greater Tucson."
The general spluttered. "Sir! The radiation! The blast! How can you say-"
Avery raised his hand and smiled for silence. There was a sense of noblesse oblige and faint menace in the action. "In a moment, General. Bear with me. It is true: There was an explosion and some radiation. But I assure you no one besides the Authority has nuclear weapons. If there were, we would deal with them by methods you all know.
"In fact, if you consult your records, you will find that the center of the blast area coincides with the site of a ten-meter confinement sphere generated - " he pretended to consult his notes" -5 July 1997."
He saw various degrees of shock, but no questions broke the silence. He wondered how surprised they really were. From the beginning, he'd known there was no point in trying to cover up the source of the blast. Old Alex Schelling, the President's science adviser, would have put two and two together correctly.
I know that several of you have studied the open literature on confinement," and you, Schelling, have spent a good many thousand cautious man-hours out in the Sandia ruins, trying to duplicate the effect, "but a review is in order.
"Confinement spheres-bobbles-are not so much force fields as they are partitions, separating the in- and outside of their surfaces into distinct universes. Gravity alone can penetrate. The Tucson bobble was originally generated around an ICBM over the arctic. It fell to earth near its target, the missile fields at Tucson. The hell bomb inside exploded harmlessly, in the universe on the far side of the bobble's surface.
"As you know, it takes the enormous energy output of the Authority's generator in Livermore to create even the smallest confinement sphere. In fact, that is why the Peace Authority has banned all energy-intensive usages, to safeguard this secret of keeping the Peace. But once established, you know that a bobble is stable and requires no further inputs to maintain itself."
"Lasting forever," put in old Schelling. It was not quite a question.
"That's what we all thought, sir. But nothing lasts forever. Even black holes undergo quantum decay. Even normal matter must eventually do so, though on a time-scale beyond imagination. A decay analysis has not been done for confinement spheres until quite recently." He nodded to an assistant who passed three heavy manuscripts across the table to the NM officials. Schelling scarcely concealed his eagerness as he flipped past the Peace Authority Secret seal -the highest classification a government official ever saw-and began reading.
