Then over the horizon lanced a painfully bright comet; there was a collective indrawn gasp, punctuated by scattered cries. The brilliant white line curved down toward them, then shot over their heads in an instant, disappearing over the eastern horizon. There hadn’t even been time to catch one’s breath as it passed. A moment later the ground trembled slightly under their feet, and the silence was broken by exclamations. To the east a cloud shot up, redefining the height of the sky’s pink dome; it must have plumed 20,000 meters.
Then another brilliant white blaze crossed the sky overhead, trailing comet tails of fire. Then another, and another, and a whole blazing cluster of them, all crossing the sky and dropping over the eastern horizon, down into great Marineris. Finally the shower stopped, leaving the witnesses in Cairo half-blinded, staggering, afterimages bouncing in their sight. They had been passed over.

“Now comes the U.N.,” Frank said. “At best.”
“Do you think we ought to . . .” Maya said. “Do you think we’re . . .”
“Safe in their hands?” Frank said acidly.
“Maybe we should take to the planes again.”
“In daylight?”
“Well, it might be better than staying here!” she retorted. “I don’t know about you, but I don’t want to just get lined up against a wall and shot!”
“If they’re UNOMA they won’t do that,” Sax said.
“You can’t be sure,” Maya said. “Everyone on Earth thinks we’re the ringleaders.”
“There aren’t any ringleaders!” Frank said.
“But they want there to be ringleaders,” Nadia said.
This stilled them.
Sax said mildly, “Someone may have decided things will be easier to control without us around.”

More news of impacts in the other hemisphere came in, and Sax settled down before the screens to follow it. Helplessly Ann stood over his right shoulder to observe it as well; these kinds of strikes had happened all the time back in the Noachian, and the chance to see one live was too much for her to pass up, even if it was the result of human agency.
While they watched, Maya continued to urge them to do something— to leave, to hide, whatever, just something. She swore at Sax and Ann both when they didn’t respond. Frank left to see what was happening at the spaceport. Nadia accompanied him to the door of the city offices, afraid that Maya was right, but unwilling to listen anymore. She said good-bye to Frank and stood before the city building, looking at the sky. It was afternoon, and the prevailing westerlies were beginning to sweep down the slope of Tharsis, bringing with them dust from the impacts. It looked like smoke in the sky, as if there were a forest fire on the other side of Tharsis. The light inside Cairo dimmed as the dust clouds obscured the sun, and the tent’s polarization created short rainbows and sundogs, as if the very fabric of the world were unraveling into kaleidoscopic parts. Huddled masses, under a burning sky. Nadia shivered. A thicker cloud covered the sun like an eclipse. She went indoors, out of its shadow, back into the offices. Sax was saying, “Very likely to begin another global.”
“I hope it does,” Maya said. She was pacing back and forth like a great cat in a cage. “It will help us escape.”
“Escape where?” Sax asked.
Maya sucked air in through her teeth. “The planes are stocked. We could go back to the Hellespontus Montes, to the habitats there.”
“They’d see us.”
Frank came onto Sax’s screen. He was staring into his wristpad, and the image quivered. “I’m at the west gate with the mayor. There’s a bunch of rovers outside. We’ve locked all the gates because they won’t identify themselves. Apparently they’ve surrounded the city, and are trying to broach the physical plant from the outside. So everyone should get their walkers on, and be ready to go.”
“I told you we should have left!” Maya cried.
“We couldn’t have,” Sax said. “Anyway, our chances may be just as good in some sort of melee. If everyone makes a break for it at once, they might be overwhelmed by numbers. Now look, if anything happens, let’s all meet at the east gate, okay? You go ahead and go. Frank,” he said to the screen, “you should get over there too when you can. I’m going to try some things with the physical-plant robots that should keep those people out until dark at least.”
It was now three p.m., although it seemed like twilight, as the sky was thick with high, rapidly moving dust clouds. The forces outside identified themselves as UNOMA police, and demanded to be let in. Frank and Cairo’s mayor asked them for authorization from U.N. Geneva, and declared a ban on all arms in the city. The forces outside made no reply.
