Isaac Mannheim gazed down through the glass partition of the old Bell Jetranger and wondered again what he was seeing. The pilot couldn't raise Command on the radio, and now he was grumbling that the pad looked unsafe.

The boy had a point. The surrounding hurricane fence had been half ripped away, and there was oil everywhere on the asphalt. The place looked as though a raging bull elephant had powered its way through, knocking aside everything in its wake. What in blazes had happened? A tornado?

He surveyed the area, and something even more ominous caught his eye. What was it, that thing half-buried in the trees, about two-thirds the way up the mountain? Now he strained to see through the smudgy windows, just making out the wreckage of some sort of military helicopter.

Next he turned and looked in the other direction, down toward the launch vehicles. That's odd. Another helicopter was parked down there. It was big, a military gray, but no one was around it.

"It looks like there was a crash on the pad or something," the young Greek pilot shouted over the roar of the engines, his dark, serious eyes fixed gravely on the scene. His name, sewn in Greek on his tan shirt, was Mikis; his father owned the 1981 Jetranger, and the business. Flying this far from Athens meant he would have to refuel to make it back, and nobody was around to take care of that. Moreover, the situation definitely looked unsafe.

"I can see that," Mannheim responded dryly, his voice faint above the noise. "Which is why you need to be careful. We don't want to add another casualty."

"Something funny is definitely going on," Mikis continued, to no one in particular. He had already discovered the eccentric American professor with a baseball cap didn't care all that much for small talk. And he had no patience whatsoever for small talk that pointed out the obvious. "I don't like this, but I'll have to put her down. I'm already on my auxiliary tank."

For once Mannheim allowed his thoughts to stray to the concerns of someone else. "There's an airfield at Kythera. You could make it there, if you just touched down here and dropped me off."

"Are you sure you want to do that?" Mikis was gripping the stick, frowning behind his aviator shades. "We can't raise anybody here on the radio, and now there's this mess. Let me take you to Kythera with me. The whole deal looks weird."

"No," Mannheim shouted back. "I have to find out what's happened."
