Had Albert been a student of the New Testament, he would have understood how Saul, that most zealous persecutor of the early Christians, must have felt when the scales fell from his eyes on the road to Damascus. He stared at Robert Jenkins with shining enthusiasm, every vestige of sleepiness banished from his brain.

Of course, when you thought about it — or when somebody like Mr Jenkins, who was clearly a real head, ratty sport-coat or no ratty sport-coat, thought about it for you — it was just too big and too obvious to miss. Almost the entire cast and crew of American Pride’s Flight 29 had disappeared between the Mojave Desert and the Great Divide... but one of the few survivors just happened to be  — surprise, surprise! — another American Pride pilot who was, in his own words, “qualified to fly this make and model — also to land it.”

Jenkins had been watching Albert closely, and now he smiled. There wasn’t much humor in that smile. “It’s a tempting scenario,” he said, “isn’t it?”

“We’ll have to capture him as soon as we land,” Albert said, scraping one hand feverishly up the side of his face. “You, me, Mr Gaffney, and that British guy. He looks tough. Only... what if the Brit’s in on it, too? He could be Captain Engle’s, you know, bodyguard. Just in case someone figured things out the way you did.”

Jenkins opened his mouth to reply, but Albert rushed on before he could.

“We’ll just have to put the arm on them both. Somehow.” He offered Mr Jenkins a narrow smile — an Ace Kaussner smile. Cool, tight, dangerous. The smile of a man who is faster than blue blazes, and knows it. “I may not be the world’s smartest guy, Mr Jenkins, but I’m nobody’s lab rat.”

“But it doesn’t stand up, you know,” Jenkins said mildly.

Albert blinked. “What?”

“The scenario I just outlined for you. It doesn’t stand up.”

“But — you said—”

“I said if it were just the plane, I could come up with a scenario. And I did. A good one. If it was a book idea, I’ll bet my agent could sell it. Unfortunately, it isn’t just the plane. Denver might still have been down there, but all the lights were off if it was. I have been coordinating our route of travel with my wristwatch, and I can tell you now that it’s not just Denver, either. Omaha, Des Moines — no sign of them down there in the dark, my boy. I have seen no lights at all, in fact. No farmhouses, no grain storage and shipping locations, no interstate turnpikes. Those things show up at night, you know — with the new high-intensity lighting, they show up very well, even when one is almost six miles up. The land is utterly dark. Now I can believe that there might be a government agency unethical enough to drug us all in order to observe our reactions. Hypothetically, at least. What I cannot believe is that even The Shop could have persuaded everyone over our flight-path to turn off their lights in order to reinforce the illusion that we are all alone.”

“Well... maybe it’s all a fake,” Albert suggested. “Maybe we’re really still on the ground and everything we can see outside the window is, you know, projected. I saw a movie something like that once.”

Jenkins shook his head slowly, regretfully. “I’m sure it was an interesting film, but I don’t believe it would work in real life. Unless our theoretical secret agency has perfected some sort of ultra-wide-screen 3-D projection, I think not. Whatever is happening is not just going on inside this plane, Albert, and that is where deduction breaks down.”

“But the pilot!” Albert said wildly. “What about him just happening to be here at the right place and time?”

“Are you a baseball fan, Albert?”

“Huh? No. I mean, sometimes I watch the Dodgers on TV, but not really.”

“Well, let me tell you what may be the most amazing statistic ever recorded in a game which thrives on statistics. In 1957, Ted Williams reached base on sixteen consecutive at-bats. This streak encompassed six baseball games. In 1941, Joe DiMaggio batted safely in fifty-six straight games, but the odds against what DiMaggio did pale next to the odds against Williams’s accomplishment, which have been put somewhere in the neighborhood of two billion to one. Baseball fans like to say DiMaggio’s streak will never be equalled. I disagree. But I’d be willing to bet that, if they’re still playing baseball a thousand years from now, Williams’s sixteen on-bases in a row will still stand.”

“All of which means what?”

“It means that I believe Captain Engle’s presence on board tonight is nothing more or less than an accident, like Ted Williams’s sixteen consecutive on-bases. And, considering our circumstances, I’d say it’s a very lucky accident indeed. If life was like a mystery novel, Albert, where coincidence is not allowed and the odds are never beaten for long, it would be a much tidier business. I’ve found, though, that in real life coincidence is not the exception but the rule.”

“Then what is happening?” Albert whispered.

Jenkins uttered a long, uneasy sigh. “I’m the wrong person to ask, I’m afraid. It’s too bad Larry Niven or John Varley isn’t on board.”

“Who are those guys?”

“Science-fiction writers,” Jenkins said.

“I don’t suppose you read science fiction, do you?” Nick Hopewell asked suddenly. Brian turned around to look at him. Nick had been sitting quietly in the navigator’s seat since Brian had taken control of Flight 29, almost two hours ago now. He had listened wordlessly as Brian continued trying to reach someone — anyone — on the ground or in the air.

“I was crazy about it as a kid,” Brian said. “You?”

Nick smiled. “Until I was eighteen or so, I firmly believed that the Holy Trinity consisted of Robert Heinlein, John Christopher, and John Wyndham. I’ve been sitting here and running all those old stories through my head, matey. And thinking about such exotic things as time-warps and space-warps and alien raiding parties.”

Brian nodded. He felt relieved; it was good to know he wasn’t the only one who was thinking crazy thoughts.

“I mean, we don’t really have any way of knowing if anything is left down there, do we?”

“No,” Brian said. “We don’t.”

Over Illinios, low-lying clouds had blotted out the dark bulk of the earth far below the plane. He was sure it still was the earth — the Rockies had looked reassuringly familiar, even from 36,000 feet — but beyond that he was sure of nothing. And the cloud cover might hold all the way to Bangor. With Air Traffic Control out of commission, he had no real way of knowing. Brian had been playing with a number of scenarios, and the most unpleasant of the lot was this: that they would come out of the clouds and discover that every sign of human life — including the airport where he hoped to land — was gone. Where would he put this bird down then?

“I’ve always found waiting the hardest part,” Nick said.

The hardest part of what? Brian wondered, but he did not ask.

“Suppose you took us down to 5,000 feet or so?” Nick proposed suddenly. “Just for a quick look-see. Perhaps the sight of a few small towns and interstate highways will set our minds at rest.”

Brian had already considered this idea. Had considered it with great longing. “It’s tempting,” he said, “but I can’t do it.”

“Why not?”

“The passengers are still my first responsibility, Nick. They’d probably panic, even if I explained what I was going to do in advance. I’m thinking of our loudmouth friend with the pressing appointment at the Pru in particular. The one whose nose you twisted.”

“I can handle him,” Nick replied. “Any others who cut up rough, as well.”

“I’m sure you can,” Brian said, “but I still see no need of scaring them unnecessarily. And we will find out, eventually. We can’t stay up here forever, you know.”
