"No." Jack pointed for Goodley to get back into the Ops Center and find out. "If that's true, it could scratch the terrorism idea. Jesus, that's scary!"

"It's true, Jack. We've checked."

"They think ten commercial commosats are nonfunctional," Goodley said. "All the defense birds are on line, though. Our commlinks are okay."

"Find the most senior S&T guy you can find - or one of our common people - and ask him what could snuff out satellites. Move!" Jack ordered. "Where's Shaw?"

"On his way in. Going to be a while the way the roads are."

"Dan, I'll give you everything I get here."

"It'll be a two-way street." The line went dead.

The most horrible thing was that Ryan didn't know what to do next. It was his job to gather data and forward it to the President, but he had no data. What information there was would come in through military circuits. CIA had failed again, Ryan told himself. Someone had done something to his country, and he hadn't warned anyone. People were dead because his agency had failed in its mission. Ryan was Deputy Director, the man who really ran the shop for the political drone placed over his head. The failure was personal. A million people dead, maybe, and there he was, all alone in an elegant little conference room staring at a wall with nothing on it. He hunted a line to NORAD and punched it.

"NORAD," a disembodied voice answered.

"This is the CIA Operations Center, Deputy Director Ryan speaking. I need information."

"We do not have much, sir. We think the bomb exploded in the immediate vicinity of the Skydome. We are trying to estimate yield, but nothing yet. A helicopter has been dispatched from Lowery Air Force Base."

"Will you keep us posted?"

"Yes, sir."

"Thank you." That was a big help, Ryan thought. Now he knew that someone else didn't know anything.

There was nothing magical about a mushroom cloud, Battalion Chief Mike Callaghan of the Denver City Fire Department knew. He'd seen one before, as a rookie fireflghter. It had been a fire in the Burlington yards just outside the city, in 1968. A propane tank-car had let go, right next to another trainload of bombs en route to the Navy's munitions terminal at Oakland, California. The chief back then had had the good sense to pull his men back when the tank ruptured, and from a quarter mile away they'd watched a hundred tons of bombs go off in a hellish firecracker series. There had been a mushroom then also. A large mass of hot air rose, roiling as it went into an annular shape. It created an updraft, drawing air upward into its donut-shaped center, making the stem of the mushroom

But this one was much larger.

He was behind the wheel of his red-painted command car, following the first alarm, three Seagrave pumper units, an aerial ladder truck, and two ambulances. It was a pitiful first response. Callaghan lifted his radio and ordered a general alarm. Next he ordered his men to approach from up-wind.
