"Infrasonic attack," he snapped. The humming had become a wave of nausea now, and his head was beginning to throb. "Hallway's a resonance cavity. We're standing at a node."

"Can't stay here," she managed, sagging against him and gripping her own stomach.

"I know. Hang on." There were only seconds, he estimated, before they were both too sick to move, and unfortunately the Trofts had left him only one option for a response. He'd hoped to keep at least one weapon out of their view on this trip, but with no indication where their infrasonic generator was located, his lasers were useless. Clutching the unsteady Ilona to his side, out of the direct line of fire, he activated his sonic disrupter and began sweeping the ends of the hallway.

Either he was very lucky or—more likely—the Trofts had again set him up with an easy victory, because in barely four seconds the sonic beam had hit on the resonance frequency for something in the Trofts' generator. Gritting his teeth—fully aware the sonic hadn't been designed for spaces this big—Jonny held the beam steady as his nanocomputer increased amplitude... and abruptly the nausea began fading. Within a dozen heartbeats all that remained of the attack were weak knees and residual aches throughout his body.

"Come on, we've got to keep going," he told Ilona thickly, stumbling toward the door she'd pointed out earlier.

"Yeah," she agreed, and did her best to comply. He wound up mostly carrying her anyway, a task that would have been impossible without his servos. Reaching the door, he pulled it open.

The Trofts had gone back to being unsubtle. This room, unlike all the previous ones, was almost literally loaded with furniture... and behind each piece seemed to be an enemy soldier.

It occurred to Jonny in that first frozen millisecond that deviating from Ilona's remembered path might well be disastrous, if for no other reason than panicking the Troft commander. But there was no way he was going to willingly face a roomful of enemies if another possibility existed... or could be made.

A single, untuned blast from his sonic was all he had time for before slamming the door to; with luck, it would jar them at least enough to slow any pursuit. Grabbing Ilona's arm, he sprinted to the next door, the last one at this end of the hall.

"This isn't the way I came!" she yelped as he let go and tried the door. It was locked, of course.

"No choice. Hit the ground and yell if you see anyone coming." His fingertip lasers were already spitting destruction at the door's edges, tracing a dashed-line pattern that would yield maximum weakening in minimum time. Halfway through he kicked hard at the door; finishing it, he kicked again. With the second kick he felt it give, and four kicks later the panel abruptly shattered. Ilona right behind him, he ducked through.

And it was instantly clear they were off the path so carefully set up for them. No human-style furniture or equipment here—from floor to ceiling the room was jarringly alien. Long, oddly shaped couches lay grouped around what looked like circular tables with hemispherical domes rising from their centers. On the walls were almost archaic-looking murals alternating with smaller bits of gleaming electronics. Across the room Jonny got just a glimpse of a Troft back-jointed leg as the alien beat a hasty retreat... and in the relative silence a sound heretofore conspicuous by its absence could be heard: the thin ululating wail of a Troft alarm.

"Dining room?" Ilona asked, glancing around.

"Lounge." A minor disappointment; he'd rather hoped they would wind up somewhere his arc-thrower could be put to use. The control room for the wall defenses, for example.

On the other hand...

"Let's get going," Ilona urged, throwing apprehensive glances at the ruined door behind them. "That crowd will be on our backs any minute."

"Just a second," Jonny told her, scanning the walls. Trofts always put lounges and other noncritical facilities on the outer edges of their bases... and, half-hidden by the murals, he finally spotted what he was looking for: the outline of a window.

Well boarded up, of course. A dark sheet of kyrelium steel, three meters by one, fitted precisely into the opening, leaving only a hairline crack in the otherwise featureless slate-gray wall. Unbreakable with even Cobra weaponry; but if the designer had followed standard Troft building reinforcement procedures, there might be a chance of getting off this treadmill right here. "Get ready to follow," he called to Ilona over his shoulder. Leaning hard into the floor, he charged the window and jumped, turning feet first in midair and hitting the window shield dead center.

The panel popped neatly from its casing and clattered to the ground outside. Jonny, much of his momentum lost, landed considerably closer to the building. Dropping into a crouch, he activated his light amp equipment and looked quickly around him.

He was in what had probably once been an extensive flower bed, extending most of the way out to where the stunted bushes and trees of an elaborate haiku garden began, the latter shifting in turn to a band of full-sized trees near the outer wall. No cover until the trees—Jonny's rangefinder set the distance at about fifty-two meters. The wall itself... thirty meters further.

Behind him came a noise. He twisted around, vaguely aware that the action hurt, to see Ilona jump lightly to the ground. "That was one beaut of a kick," she hissed as she joined him in his crouch.

"Not really. The edges are beveled against impacts from the outside only. Any idea where we are?"

"West side of the house. Gate's around to the north."

"Never mind the gate—we can go over the wall just as easily here." A corner of Jonny's mind considered the possibility that the Trofts had spy-mikes on them. "First, though," he added for their benefit, "I want to see if the house lasers are set to fire on outgoing targets."

Still no sign of enemy soldiers. Moving to the former window cover, he hefted the metal for a quick examination. Kyrelium steel, all right, about five centimeters thick. He had no idea whether it would do for what he had in mind, but there was no time left to find anything better. Bracing himself firmly, he gripped the panel on either side, raised it over his head like a makeshift umbrella... and with everything his servos could manage, he hurled it toward the distant wall.

He'd never gone to the limit in quite this way, and for a long, horrifying moment he was afraid he'd thrown the panel too hard. If it cleared the wall—and in the process ruined his pretense of ignorance as to the defensive lasers there—

But he actually had nothing to fear. The panel arced smoothly into the sky and dropped with a crash of breaking branches into the middle of the distant patch of forest, a good twenty meters in from the wall.

And it made the whole trip without drawing any fire.

Jonny licked his lips. So the automatics would most likely leave them alone. Would the live gunners who were undoubtedly up there abstain as well? There was nothing he could do about that but hope that they were still relying on the wall itself to ultimately stop him. If they were... and if his plan worked...

"Ready for a run?" he whispered to Ilona.

Her eyes were still on the spot where the kyrelium plate had ended its flight. "Phrij and a half," she muttered. "Uh—yeah, I'm ready. Toward the wall?"

"Right. As fast as you can. I'll be behind you where I can theoretically handle anyone who tries to stop us." One final look around—"okay; go."

She took off like the entire Troft war machine was after her, running in a half-crouched posture that offered at best an illusion of relative safety. Jonny let her lead him by perhaps five meters, enhanced vision and hearing alert for any sound of pursuit. But the Tyler Mansion might have been deserted for all the response they drew from it. All lined up on the balcony to watch us slag ourselves, no doubt, he thought, recognizing as he did so that the strain was beginning to affect him. A few more seconds, he told himself over and over, the words settling into the quick rhythm of his footsteps. A few more seconds and it'll be over.
