The first blast of air came from above my head, a roar that quickly built to hurricane intensity. I stiffened my body to steady myself. My clothes flapped and pressed flat against my body. The wind increased, threatening to tear the bag from my hand. Then the air stopped for a moment, and a second blast came upward from the floor. It was disorienting, but it only lasted a few moments. Then with a whoosh the vacuum pumps kicked in and I felt a slight ache in my ears as the pressure dropped, like an airplane descending. Then silence. A voice said, "That's it. Come ahead."
I opened my eyes. The liquid they'd sprayed on me had evaporated; my clothes were dry. The doors hissed open before me. I stepped out and the man in blue looked at me quizzically. "Feel okay?"
"Yeah, I think so."
"No itching?"
"No…"
"Good. We had a few people who were allergic to the stuff. But we've got to do this routine, for the clean rooms."
I nodded. It was obviously a procedure to remove dust and other contaminants. The dousing fluid was highly volatile, evaporating at room temperature, drawing off microparticles on my body and clothes. The air jets and vacuum completed the scrub. The procedure would remove any loose particles on my body and suck them away.
"I'm Vince Reynolds," the man said, but he didn't hold out his hand. "You call me Vince. And you're Jack?"
I said I was.
"Okay, Jack," he said. "They're waiting for you, so let's get started. We got to take precautions, because this is an HMF, that's high magnetic field environment, greater than 33 Tesla, so…" He picked up a cardboard box. "Better lose your watch." I put the watch in the box.
"And the belt."
I took my belt off, put it in the box.
"Any other jewelry? Bracelet? Necklace? Piercings? Decorative pins or medals? MedicAlert?"
"No."
"How about metal inside your body? Old injury, bullets, shrapnel? No? Any pins for broken arms or legs, hip or knee replacement? No? Artificial valves, artificial cartilage, vascular pumps or implants?"
I said I didn't have any of those things.
"Well, you're still young," he said. "Now how about in your bag?" He made me take everything out and spread it on a table, so he could rummage through it. I had plenty of metal in there: another belt with a metal buckle, nail clippers, a can of shaving cream, razor and blades, a pocket knife, blue jeans with metal rivets…
He took the knife and the belt but left the rest. "You can put your stuff back in the bag," he said. "Now, here's the deal. Your bag goes to the residence building, but no farther. Okay? There's an alarm at the residence door if you try to take any metal past there. But do me a favor and don't set it off, okay? 'Cause it shuts down the magnets as a safety procedure and it takes about two minutes to start 'em up again. Pisses the techs off, especially if they're fabbing at the time. Ruins all their hard work."
I said I would try to remember.
"The rest of your stuff stays right here." He nodded to the wall behind me; I saw a dozen small safes, each with an electronic keypad. "You set the combination and lock it up yourself." He turned aside so I could do that.
"I won't need a watch?"
He shook his head. "We'll get you a watch."
"What about a belt?"
"We'll get you a belt."
"And my laptop?" I said.
"It goes in the safe," he said. "Unless you want to scrub your hard drive with the magnetic field." I put the laptop in with the rest of my stuff, and locked the door. I felt strangely stripped, like a man entering prison. "You don't want my shoelaces, too?" I said, making a joke. "Nah. You keep those. So you can strangle yourself, if it turns out you need to."
"Why would I need to?"
"I really couldn't say." Vince shrugged. "But these guys working here? Let me tell you, they're all fucking crazy. They're making these teeny-weeny little things you can't see, pushing around molecules and shit, sticking 'em together. It's real tense and detailed work, and it makes them crazy. Every fucking one of 'em. Nutty as loons. Come this way." We passed through another set of glass doors. But this time, there was no spray. …
We entered the power plant. Beneath blue halogen lamps, I saw huge metal tubs ten feet high, and fat ceramic insulators thick as a man's leg. Everything hummed. I felt a distinct vibration in the floor. There were signs all around with jagged red lightning bolts saying warning: lethal electrical currents!
"You use a lot of power here," I said.
"Enough for a small town," Vince said. He pointed to one of the signs. "Take those warnings seriously. We had problems with fires, a while back."
"Oh?"
"Yeah. Got a nest of rats in the building. Buggers kept getting fried. Literally. I hate the smell of burning rat fur, don't you?"
"Never had that experience," I said.
"Smells like what you'd think."
"Uh-huh," I said. "How did the rats get in?"
"Up through the toilet bowl." I must have looked surprised, because Vince said, "Oh, you don't know that? Rats do that all the time, it's just a short swim for them to get in. 'Course, if it happened while you were sitting, it'd be a nasty surprise." He gave a short laugh. "Problem was the contractor for the building didn't bury the leach field deep enough. Anyhow, rats got in. We've had a few accidents like that since I've been here."
"Is that right? What kind of accidents?"
He shrugged. "They tried to make these buildings perfect," he said. "Because they're working with such small-size things. But it's not a perfect world, Jack. Never has been. Never will be." I said again, "What kind of accidents?"
By then we had come to the far door, with a keypad, and Vince punched in numbers quickly. The door clicked open. "All the doors are keyed the same. Oh six, oh four, oh two." Vince pushed the door wide, and we stepped into a covered passageway connecting the power plant to the other buildings. It was stifling hot here, despite the roar of the air conditioner. "Contractor," Vince explained. "Never balanced the air handlers right. We had 'em back five times to fix it, but this passage is always hot."
At the end of the corridor was another door, and Vince had me punch in the code myself. The door clicked open.
I faced another airlock: a wall of thick glass, with another wall a few feet beyond. And behind that second wall, I saw Ricky Morse in jeans and a T-shirt, grinning and waving cheerfully to me.
His T-shirt said, "Obey Me, I Am Root."
It was an inside joke. In the UNIX operating system, it meant the boss.
Over an intercom speaker, Ricky said, "I'll take it from here, Vince."
Vince waved. "No problem."
"You fix that positive pressure setting?"
"Did it an hour ago. Why?"
"It may not be holding in the main lab."
"I'll check it again," Vince said. "Maybe we got another leak somewhere." He slapped me on the back, jerked his thumb toward the interior of the building. "Lots of luck in there." Then he turned and walked back the way he came.
"It's great to see you," Ricky said. "You know the code to get in?" I said I did. He pointed to a keypad. I punched the numbers in. The glass wall slid sideways. I stepped into another narrow space about four feet wide, with metal grills on all four sides. The wall closed behind me.
A fierce blast of air shot up from the floor, puffing up my trouser legs, ruffling my clothing. Almost immediately it was followed by blasts of air coming from both sides, then from top, blowing down hard on my hair and shoulders. Then a whoosh of vacuum. The glass in front of me slid laterally. I smoothed down my hair and stepped out.
