"Sometimes you get stuck in a trap of your own design." He limped to the window to collapse onto the deep sill. "I didn't know what Tomtom had done to the other scientists, just that they were dead, and they needed someone that could pa.s.s to find Dufae's son."

"Why the h.e.l.l did you even get involved with them? You nearly have a doctorate of physics, why the h.e.l.l would you give it all up to be a tool on some backa.s.s world?"

"You wouldn't understand." Riki fumbled through his pockets, found the MP3 player, gazed at it sadly, and put it away to pull out cigarettes.

"No, I don't. Nothing could make me do what you're doing."

"Really?" He tapped out a cigarette, his motions slow, like he was moving through deep water. "What if someone sealed away your intelligence? Made you an idiot but left the memories of your brilliance? At night you'd dream that you were smart again, creating clever gadgets, having that wildfire of creativity, and wake up to find it all ashes. What would you do to get it back?"

She swallowed down sudden terror. "I wouldn't do this."

"Liar," Riki whispered. He clicked his tongue and the cigarette lit.

"What is it that you get out of this deal?"

"I'm a tengu." He took a deep drag off the cigarette, and languidly raised the hand to rest against his temple. "Hard wired in this brain is the instinct of flight. Millions of years of evolution focused on that one thing, tightly packed away," he held out his hand, showing it innocent of feathers, "in a body that can't fly. You can't imagine-even with your marvelous brain-what an endless torture it is. Tengu don't die of old age on Earth-sooner or later, they just climb the tallest mountain and throw themselves off, just to feel that oneness with the sky."

"There's hang gliding."

Riki's shoulder shook with a short, silent laugh. "Hang gliding, parachuting, high diving...I could name them all, but the thing is, you only go down, you never come back up."

"You could have just gone to Elfhome. Obviously the spell works there."

"When people throw themselves off mountains, normally there's not much left to salvage." He took another long drag on his cigarette. "But we tried. We skinned the bodies of the old ones who had the tattoo, preserving them for centuries, waiting for a chance to have our wings and our freedom at the same time, slowly going mad."

"But it didn't work, so you sold yourself back into slavery."

"Yes," he murmured and then looked sharply at Chiyo. "Hey! Chiyo! You can't go to sleep!"

"I'm so tired," Chiyo moaned.

Riki sighed, and gave a sharp whistle. The guard from the hall opened the door and looked in. Riki flicked the hand with the cigarette, giving a command in rapid Oni. The guard glanced at Chiyo, then to Tinker, nodded and went out.

"What?" Tinker asked.

"We have a slight personnel problem. One of Chiyo's cousins was killed in a car accident the Shutdown we missed our kill on Windwolf. It leaves us shorthanded."

Things suddenly clicked for Tinker. The oni were the smugglers; the high-tech goods were for building the gate. Chiyo's cousin must have been the pinned driver who had been shot by the other oni, rather than let him fall into EIA hands and be questioned. Tinker looked sharply at the female; if someone had killed Oilcan, she would-she would...She couldn't finish the thought, the possibilities of Oilcan being caught and hurt in all this was all too real for idle speculation.

"So." Tinker distracted herself with details. "We're missing materials for the gate?"

"No. Lord Tomtom is quite methodical. We have a surplus of everything."

The door opened and the guard came back, carrying a saijin saijin flower. flower.

"What's that for?" Tinker scrambled backward, away from the guard.

"It's time for you to sleep." Riki took another drag on his cigarette, and breathed the smoke out his long sharp nose.

"I don't need that. I'll sleep without it."

"We have to be sure. Please, just take it nicely. With what I'm buzzing on for the pain-" he lifted his foot that she had broken "-I don't trust myself not to hurt you."

Sullenly, she held her hand for the flower, and with everyone watching closely, breathed deeply of its false comfort.

Tinker drifted out of the white fog of drugged slumber, opening her eyes to an unfamiliar ceiling. Where was she? Sleep still clung to her with pulled taffy strength, making it hard to think. She dragged her hand free of the blankets to rub at her eyes, trying to force herself awake. As she moved, she felt the spider again, picking its way carefully across her forehead. She smeared her hand up, over her brow, and combed her fingers on through her hair, finding nothing. What the h.e.l.l? What the h.e.l.l?

The ceiling had changed.

She frowned at the expanse of white, now recognizable as the one above her futon on Onihida. Wait, the ceiling hadn't changed-or had it? Both ceilings had been featureless white; she couldn't say how one was strange and the other familiar. And why would anyone swap ceilings? That didn't make sense. Maybe it had been a trick of lighting. She sat up, knowing that something was wrong, but still not sure what.

Chiyo sat in her corner wearing a fresh kimono and a smug smile.

Tinker fumbled her way into the clothes Riki had brought her the night before, trying to think past the fog banks rolling through her mind. The Levi jeans distracted her from the ceiling mystery. The blue jeans were men's thirty-by-thirty carpenters, which she usually wore, but brand-new. She puzzled over them a moment-wondering how they had gotten the correct size and type-before realizing that Riki probably had just checked the dresser in her workshop. Oilcan might have noticed missing clothes, so the oni bought her a new wardrobe. The oni's thoroughness depressed her.

Riki arrived as she was putting on her boots. Annoyingly, his bruises had faded during the night to almost nothing.

"It wasn't an elf," Tinker said to him.

"What?"

"You said it was an elf that beat you up at the Faire the night Windwolf changed me. It couldn't have been-you would have been healed by the time I got back three days later."

"Tomtom had me beaten," Riki admitted. "He didn't think you were coming back. I convinced him that you'd come back eventually for your cousin's sake, so he let me off lightly."

Tinker grunted at the oni's idea of "lightly." "I want something to eat, and then we can talk about this gate you want me to build."

At least they had good food: smoked trout, eggs poached in heavily salted water, and a sweet, orange-yellow, soft fruit peeled and sliced, all dumped on top of a huge bowl of nutty-flavored, dark brown rice. The only thing she didn't like were oddly pickled vegetables. Chiyo and Riki ate them in a resigned manner.

Riki explained that they were traditional staples from Lord Tomtom's region; apparently in the warmer climates, pickling was the easiest way to preserve food. "And the cook is a seven-foot-tall shankpa shankpa whose family died in a famine. He takes wasted food personally." whose family died in a famine. He takes wasted food personally."

Shankpa? Tinker refused to ask on the grounds that at some point ignorance started to sound like idiocy. She'd find out later.

"You don't send plates back with food on them." Chiyo tipped her bowl to show it was empty.

"I see." Tinker picked up her pickles and dumped them into Chiyo's bowl.

Chiyo looked laughably stunned for a moment, and then her lip curled back into a snarl. The look vanished away with one murmured word from Riki.

"What's the magic word?" Tinker asked him as they walked the maze of identical stone hallways.

"Which one?"

She attempted to reproduce the word; apparently she didn't come close because Riki puzzled a moment.

"Ah," he said. "That's the act of being deboned."

At the workshop, she found a distance measurer and a piece of chalk. She walked around the vast room, pointing the instrument at the distant walls.

"What are you doing?" Riki perched on a workbench. He'd sent Chiyo off on some errand, much to everyone's relief.

"I'm measuring the room to find its exact size so we can model it on the computer." Tinker tapped the b.u.t.ton, called the measurement to Sparks, marked the floor and moved down roughly a foot. "If we're building the gate in this room, then we need to know the maximum size it can be." She paused. "You do want it built in here, don't you?"

"Yes."

"I thought so, judging by your notes and what you told Russell."

"You found that?"

"Yes."

Riki winced but said nothing.

"The gate in orbit is just over twenty-six hundred feet in diameter, basically half a mile." She finished the width measurement and started on length. "The ceiling is going to be the prime determiner. Depending on the slope of the ceiling and the various support beams, it's going to be somewhere between twenty and thirty feet in diameter."

"Russell maintained that it couldn't be scaled down."

"It was only designed that size to allow for s.p.a.ceships to pa.s.s through it. Didn't you show him my father's notes?"

"There's nothing on how Dufae decided on its size."

G.o.ds save her from idiots. "What do you think all the technical specs on the s.p.a.ce shuttle were about? He was trying to plot out the minimum size of a colony ship. At minimum, a colony would need something that could safely land people on a planet. He thought that anything going out should be able to have a shuttle riding piggyback on it and still fit through the gate."

"Doh!" Riki said, sounding very human.

Scaling it down presented a host of problems. With the large surface to play with, her father hadn't bothered to economize his design, and the Chinese apparently hadn't dared to deviate from the stolen plans. She'd have to use every trick she knew to compact the circuits. "Where is the ceramic coming from? You said we have surplus of everything."

"We've been stockpiling ceramic tiles for nearly fifteen years. They decided early on, though, that the shield material wasn't needed."

"Yeah, that's just to protect the gate from micrometeor impacts and solar wind." Tinker finished up her measurements by taking the ceiling readings at every grid point that she had chalked on the floor. "Sparks, render that for me."

"Okay, Boss."

While she waited she considered the scale ratio. The easiest might be a simple one to a hundred ratio: 2640 feet shrinking to 26.4.

"Done, Boss." The AI projected it onto the screen.

She snapped out a circle to represent the scaled down gate and moved it around the workshop. G.o.ds, manufacturing the d.a.m.n framework was going to be a b.i.t.c.h. The nonconductive material used in s.p.a.ce wouldn't stand up to gravity. While steel could take the stress load, the amount of metal needed to make the gate would play havoc with the system.

A good fit on the model drew her attention back to it. She locked the circle down. "Let's see if this works."

As Sparks read off the gird coordinates, she found the matching points on the workshop floor and circled them in chalk.

"Is that it?" Riki asked with quiet awe.

She snorted in disgust. "That's the easy part. Of course if I make a mistake now, we might not know until the last moment. Let me think on this for a while. Get me a list of supplies that we have, and see if you can find some more comfortable chairs."

She'd shifted the locations three times including rotating the gate half a turn as she considered factors from height clearance, use of the overhead crane during construction, the ease of getting large materials into place, and finally the local ley lines, faint as they might be. Riki reappeared with the materials list and a surprising array of office chairs just as she was spray-painting the final location onto the workshop floor. He also had a lunch of steamed fish, brown rice, and more pickles.

She took the list and studied it as she ate. Again, she found the oni depressingly efficient, though noncreative; they had slavishly gathered what had been used to build the orbital gate and nothing else. "We need something for the superstructure of the gate, something inert and nonmetallic. If we were on Elfhome, I'd use ironwood. I don't suppose you have something similar?"

"Ironwood?"

"Yeah."

"You want to use ironwood?"

She flicked her pickles at him. "h.e.l.lo! That's what I said. I know you understand English, Mr. Born-and-raised in Berkeley."

"It's just using wood is so low tech."

"To quote you-doh! From little minds come no solutions. Ironwood is stunningly strong, renewable, non-toxic, recyclable, and easy to work with. Do the oni have anything like it or not?"

"We can get ironwood."

She waited for explanations but they weren't forthcoming.

"I'm talking ma.s.sive timbers." She held out her hands to show the beam size.

Riki nodded. "Just tell me how much, and I'll get it."

"Okay. We're in business then."

Time blurred for the rest of the day, as she designed the wood framework. Riki came and went, searching out samples of the ceramic tiles and other materials stockpiled elsewhere. Each item fired new ideas, and she branched out to how to affix the tiles, a ramp over the threshold to protect the gate, and a preliminary sketch of the power supply grid.

Night fell, and shadows in the warehouse grew deeper. Chiyo brought dinner and almost instantly the female and Riki started bickering in Oni. Tinker sighed, leaning back in her chair to look up through the skylight. She expected the stars to be strange and unfamiliar, like the sky of Earth. First Wolf, though, was right overhead, his shoulder star the brightest thing in the sky as always. It was comforting to see it, so very familiar. Then it struck her-it was too familiar. She leaned from side to side to see more through the overhead rectangle of Plexiglas, studying the constellations. The moon spinners. The dark-eyed widow.

It was the sky of Elfhome overhead.

And suddenly it was all clear to her.

You have a prisoner, extremely intelligent, to whom you need to give great freedom and entrust with a great deal of material that could easily be twisted into weapons. Wouldn't the simplest method of holding said prisoner be simply to convince her that she is in another dimension? Even if she fled the building, the whole world would act as a prison. Escape would seem impossible.

She had to still be on Elfhome. Why else would they paint the warehouse windows to keep her from seeing outside? How else could Riki be on Elfhome prior to Shutdown and after Startup and yet have a copy of her computer system up and running? How he had access to office chairs and ironwood? How he got her to the "castle?" If Riki could pop back and forth freely between Elfhome and Onihida, carrying kidnapped girls, ergonomic workstations, and large trees, the oni had no need of a gate.

And yet, she couldn't completely explain away the city outside the windows. How had they tricked her so completely?

"Kitsune are the fox spirits," Lain had told her. "They usually appear to be beautiful women, but they really are just foxes that can throw illusions into their victim's mind."
