I got the tab, paid up, and we strolled out. Sure enough, the moon had risen.

"Car's in the hotel lot," he said as we hit the street. "'This side."

He indicated a station wagon once we were back in the parking lot, unlocked it, and waved me aboard. He drove us out, turned at the nearest corner, and followed the Ala meda to the Paseo, took a right leading uphill on a street called Otero and another onto Hyde Park Road. From then on traffic was very light. We passed a sign indicating that we were heading toward a ski basin.

As we worked our way through many curves, heading generally upward, I felt a certain tension going out of me. Soon we had left all signs of habitation behind us, and the night and the quiet settled fully No streetlights here. Through the opened window I smelled pine trees. The air was cool. I rested, away from S and everything else.

I glanced at Luke. He stared straight ahead, brow furrowed. He felt my gaze, though, because he seemed to relax suddenly and he shot me a grin.

"Who goes first?" he asked.

"Go ahead," I answered.

"Okay. When we were talking the other morning about your leaving Grand D, you said you weren't going to work anywhere else and you weren't planning on teaching."

"That's right."

"You said you were just going to travel around."

"Yep"

"Something else did suggest itself to me a little later on."

I remained silent as he glanced my way.

"I was wondering," he said after a time, "whether you might not be shopping around-either for backing in getting your own company going, or for a buyer for something you have to sell. You know what I mean?"

"You think I came up with something-innovative-and didn't want Grand Design to have it."

He slapped the seat beside him.

"Always knew you were no fool," he said. "So you're screwing around now, to allow decent time for its development. Then you hunt up the buyer with the most bread."

"Makes sense," I said, "if that were the case. But it isn't."

He chuckled.

"It's okay," he said. "Just because I work for Grand D doesn't make me their fink. You ought to know that."

"I do know it."

"And I wasn't asking just to pry. In fact, I had other intentions completely. I'd like to see you make out with it, make out big."

"Thanks."

"I might even be of some assistance-valuable assistance-in the matter."

"I begin to get the drift, Luke, but-"

"Just hear me out, huh? But answer one thing first, though, v if you would: You haven't signed anything with anybody in the area, have you?"

"No."

"Didn't think so. It would seem a little premature."

The roadside trees were larger now, the night breeze a bit more chill.

The moon seemed bigger, more brilliant up here than it had in the town below. We rounded several more curves, eventually commencing a long series of switchbacks that bore us higher and higher. I caught occasional glimpses of sharp drops to the left. There was no guard rail.

"Look," he said, "I'm not trying to cut myself in for nothing. I'm not asking you for a piece of the action for old times' sake or anything like that. That's one thing and business is another-though it never hurts to do a deal with someone you know you can trust. Let me tell you some of the facts of life. If you've got some really fantastic design, sure, you can go sell it for a bundle to lots of people in the business-if you're careful, damn careful. But that's it. Your golden opportunity's flown then. If you really want to clean up, you start your own outfit. Look at Apple. If it really catches on you can always sell out then, for a lot more than you'd get from just peddling the idea. You may be a whiz at design, but I know the marketplace. And I know people-all over the country-people who'd trust me enough to bankroll us to see it off the ground and out on the street. Shit! I'm not going to stay with Grand D all my life. Let me in and I'll get us the financing. You run the shop and I'll run the business. That's the only way to go with something big."

"Oh, my," I sighed. "Man, it actually sounds nice. But you're following a bum scent. I don't have anything to sell."

"Come on!" he said. "You know you can level with me. Even if you absolutely refuse to go that way, I'm not going to talk about it. I don't screw my buddies. I just think you're making a mistake if you don't develop it yourself."

"Luke, I meant what I said."

He was silent for a little while. Then I felt his gaze upon me again.

When I glanced his way I saw that he was smiling.

"What," I asked him, "is the next question?"

"What is Ghostwheel?" he said.

"What?"

"Top secret, hush-hush, Merle Corey project. Ghostwheel," he answered. "Computer design incorporating shit nobody's ever seen before. Liquid semiconductors, cryogenic tanks, plasma-"

I started laughing.

"My God!" I said. "It's a joke, that's what it is. Just a crazy hobby thing. It was a design game-a machine that could never be built on Earth. Well, maybe most of it could. But it wouldn't function. It's like an Escher drawing-looks great on paper, but it can't be done in real life."

Then after a moment's reflection, I asked, "How is it you even know about it? I've never mentioned it to anyone."

He cleared his throat as he took another turn. The moon was raked by treetops. A few beads of moisture appeared upon the windshield.

"Well, you weren't all that secret about it," he answered. "There were designs and graphs and notes all over your work table and drawing hard any number of times I was at your place. I could hardly help but notice. Most of them were even labeled ‘Ghostwheel.' And nothing anything like it ever showed up at Grand D, so I simply assumed it was your pet project and your ticket to security. You never impressed me as the impractical dreamer type. Are you sure you're giving this to me straight?"

"If we were to sit down and build as much as could be constructed of that thing right here," I replied honestly, "it would just sit there and look weird and wouldn't do a damned thing."

He shook his head.

"That sounds perverse," he said. "It's not like you, Merle. Why the hell would you waste your time designing a machine that doesn't function?"

"It was an exercise in design theory" I began.

"Excuse me, but that sounds like bullshit," he said. "You mean to say there's no place in the universe that damn machine of yours would kick over?"

"I didn't say that. I was trying to explain that I designed it to operate under bizarre hypothetical conditions."

"Oh. In other words, if I find a place like that on another world we can clean up?"

"Uh, yeah."

"You're weird, Merle. You know that?"

"Uh-huh."

"Another dream shot to shit. Oh, well . . . Say, is there anything unusual about it that could be adapted to the here and now?"

"Nope. It couldn't perform its functions here."

"What's so special about its functions, anyhow?"

"A lot of theoretical crap involving space and time and some notions of some guys named Everett and Wheeler. It's only amenable to a mathematical explanation."

"You sure?"

"What difference does it make, anyhow? I've got no product, we've got no company. Sorry. Tell Martinez and associates it was a blind alley."

"Huh? Who's Martinez?"

"One of your potential investors in Corey and Raynard, Inc.," I said. "Dan Martinez-middle-aged, a bit short, kind of distinguished-looking, chipped front tooth . . ."

His brow furrowed. "Merle, I don't know who the hell you're talking about."

"He came up to me while I was waiting for you in the bar. Seemed to know an awful lot about you. Started asking questions on what I can now see as the potential situation you just described. Acted as if you'd approached him to invest in the thing."
