She put her book down, finished off the glass in a couple of gulps, and went to refill it. From the kitchen she could hear a commotion going on outside. She filled the glass and took it out onto Pepe's balcony.

A circle of young people was dancing in the creek, laughing and singing. About half were naked, in spite of the cold water. Crowds on both banks were clapping and shouting. "Take it off, take it off."

Well, they were expecting a message of peace and hope in a few hours. What would they actually get?

She closed her eyes and suddenly opened them, just in time to keep from dropping the expensive crystal over the balcony. Her arms and legs were heavy with fatigue. She went into Pepe's bedroom and manually set the clock to wake her at five forty-five, not trusting the voice controls. Exactly three hours of sleep. She was unconscious before it said two forty-six.

When the clock woke her she staggered downstairs and got breakfast from machines, guaranteed bad coffee and a candy bar. They didn't have any Mars bars, unfortunately, so she picked one at random. Did they still make Mars bars? She hadn't bought a candy bar in twenty-some years. The chocolate was unpleasantly rich and sweet. But it would get her through to the end of the world.

She was mildly surprised not to have been rousted out of bed by FBI agents. Whatever Pepe was, he was evidently not on their side.

She turned on the cube and switched it to Channel 7, hoping to catch Marya. Some male voice-over was describing the procession of notables, showing footage of one helicopter after another alighting on the same landing pad, dropping off this or that president or prime minister or movie star. A large stand of bleachers filled up with people not accustomed to sitting in bleachers. The rising sun was behind them; the sky was salmon deepening to perfect blue.

At precisely six, a U.S. Marine Corps helicopter, number 1, came in and disgorged President Davis and his retinue, including a squad of heavily armed marines. Rory smiled at that. They wouldn't be much help against planet-busting aliens, but they might prevent him from sharing the fate of his predecessor. She had been following his career from Cuba; he was the least popular president since Nixon. A majority of the House and Senate wanted him impeached, if not actually hanged, but they were putting it off for a few days. Maybe the aliens would vaporize him and save them the trouble.

After the old man was safely installed on the dais in front of the bleachers, seated uncomfortably close to the secretary-general of the UN, the cube switched to a telescopic view of the alien ship. It didn't seem fundamentally different from a human spaceship, which could just be form following function. Or perhaps they wanted to reassure us.

Or, most likely, it wasa human ship, part of the biggest hoax in history. With Pepe somewhere near the center of it.

Her certainty had grown as the evidence accumulated that Pepe had obviously been planted in her department, set up to be her second-in-command. If it was a hoax, it was an enterprise larger than the Manhattan Project. The early data could have been faked, someone hacking the input from GRS-1 and its lunar counterpart. But eventually other telescopes picked it up. It didcome from outside the solar system, though perhaps not from nearly as far or going as fast as they thought.

And it did apparently crack Phobos in two, though that could conceivably have been set up beforehand. The figure of a hundred thousand megatons—"give or take a factor of a thousand"—came from Leo, but through Pepe. She'd never checked, and Leo died.

Like the president. Like Pauling, and the rest of the cabinet.

She and Norman would have been out of the picture, too, except for the coincidence of Qabil hearing about the FBI.

The four satellites, destroyed by an invisible ray—that was the easiest to explain. Simple sabotage.

In less than an hour, the last piece would fall into place, though it probably would not be conclusive. Hollywood had more than a century of experience in creating aliens.

The president gave a neutral, optimistic speech, blessedly free of spoonerisms and hysteria. The secretary-general of the UN followed, speaking in his native Bantu. Except for glottal clicks and such, it was pretty much the same speech as Davis had given. A great opportunity awaits us; we welcome our friends from space with open arms. Now that they've destroyed our otherarms.

There were lots of vehicles parked behind the bleachers—white NASA vans, a couple of military trucks, two ambulances, and a fire truck. She wondered whether one of them might conceal a last-resort bomb, and if so, who controlled the trigger.

And how big a bomb? A high helicopter showed the NASA causeway as crowded as a subway station, all the way to the dikes; over a million people waiting to watch the alien craft land. She was glad not to be there.

The cube shifted to a shimmering telescopic view of the alien craft, which had begun to de-orbit somewhere over Australia.

It might pass by overhead on its way to the Cape. She went out on the balcony to check the sky, but it was the usual gray blanket.

The partying students were gone, and had not left a mess behind. Kids nowadays. She heard muffled news broadcasts from apartments all around her, and kept the door open so she could listen for Marya or Pepe on the cube.

Not hearing Marya was no surprise. She hadn't had a chance to disappear after the "accidental" broadcast, and even if the FBI didn't take her, the network would probably have fired her or put her on ice for a while.

Overhead, the familiar double crack of a sonic boom; a spaceship on its approach path to Cape Kennedy. She went inside and sat in front of the cube.

There was Pepe, on the dais with nine other notables, behind the president, who slowly got to his feet. They all did the same.

The ship was dimly visible, descending. Rory realized she was holding her breath.

It touched down precisely at the end of the runway, about the size of a regular shuttle. It would have to be, of course, if this were a hoax—they couldn't have secretly built a spaceship from scratch. It was prettier than a regular shuttle—shiny, like chrome, and somehow it didn't use a braking parachute to slow down.

It rolled to a stop a few hundred meters from the dais, and then, with a slight hissing sound, continued on to stop directly in front of the president. A door opened in the side of the craft and a stairway unfolded to the ground.

Two human-looking figures walked down the stairs. They wore shimmering silver skintight suits, obviously male and female. They didn't walk like people who'd been in zero-gee, Rory noticed. Then she noticed they were both beautiful, despite complete hairlessness, not even eyebrows. A nice touch.

When they stepped off the staircase, it folded back into the ship. As they walked toward the dais, the ship started to hiss again, and rolled slowly down the runway.

They walked up the steps in no rush, the woman leading, and when they got to the dais, they ignored the standing notables and went straight to the microphone.

The woman spoke first: "We are not aliens from another planet. We are aliens from earth. We come from five hundred years in your future."

The man continued: "It was the largest engineering enterprise in the history of humanity. The energy we displayed approaching you was only a small fraction of what was required to bend space and time and send us back. That required the total destruction of a small star, the kind you call a brown dwarf."

"We bring a message of hope and caution," the woman said. "The message of hope is that we arehere, and therefore you do have a future. Knowing that is going to change you. The catastrophic war that seems about to begin will evaporate—and a series of things will happen, starting today, that will make war impossible within the lifetimes of most people now living."
