"Miles," said Ivan in puzzlement, "our guys wouldn't carry plasma arcs on an antipersonnel mission like this, would they? Not in the middle of a critical facility like this-they'd not want to risk damaging the machinery-"

"Painted?" said Miles urgently. "Like how? Not-not face paint like a Chinese opera mask, by chance?"

"I don't know-what a Chinese opera mask looks like," panted Mark, "But they-well, one-had colors solid from ear to ear."

"The ghem-commander, no doubt," Miles breathed. "On formal hunt. They've upped the bid, it seems."

"Cetagandans?" said Ivan sharply.

"Their reinforcements must have finally arrived. They must have picked up my trail at the shuttleport. Oh, G.o.d-and Quinn went that way... !" Miles too turned in a circle, and swallowed panic back to the pit of his stomach where it belonged. It must not be permitted to rise to the level of his brain. "But you can relax, Mark. They don't want to kill you."

"The h.e.l.l they don't! He shouted, 'There he is, men!' and tried to blow my head off!"

Miles's lips peeled back on a dirty grin. "No, no," he carolled soothingly. "Merely a case of mistaken ident.i.ty. Those people want to kill me-Admiral Naismith. It's just the ones on the other end of the tunnel who want to kill you. Of course," he added jovially, "neither of them can tell us apart."

Ivan made a derisive sputter.

"Back this way," said Miles decisively, and led on at a run. He swung into the transverse corridor and skidded to a halt before the outside access hatch. Ivan and Mark galloped up behind.

Miles stood on tiptoe, and gritted his teeth. According to the control readout, the tide had now risen higher than the top of the hatch. This exit was sealed by the sea.

Chapter Fifteen.

Miles slapped his wrist comm channel open. "Nim!" he called.

"Sir!"

"There's a Cetagandan covert ops squad in Tower Seven. Strength unknown, but they have plasma arcs."

"Yes, sir," came Nim's breathless voice. "We just found them."

"Where are you and what can you see?"

"I have a pair of soldiers outside each of the three tower entrances, with a backup in the bushes in the parking area. The-Cetagandans, you say, sir?--just pumped some plasma blasts out the main corridor as we tried to enter."

"Anybody hit?"

"Not yet. We're flat."

"Any sign of Commander Quinn yet?"

"No, sir."

"Can you get a fix on her wrist comm?"

"It's somewhere in the lower levels of this tower. She doesn't respond and it's not moving."

Stunned? Dead? Was her wrist even still in her wrist comm? No telling.

"All right," Miles took a breath, "put in an anonymous call to the local police. Tell them there's armed men in Tower Seven-maybe saboteurs trying to blow up the Barrier. Make it convincing-try to sound scared."

"No problem, sir," said Nim earnestly.

Miles wondered how nearly the plasma beam had parted Nim's hair. "Until the constables arrive, keep the Cetagandans sealed in the tower. Stun anyone who tries to exit. The locals can sort them out later. Put a couple of point men down in Tower Eight to seal that end, have them work north and drive the Cetagandans back if they try to exit south. But I think they'll head north." He put his hand over the comm and added to Mark, "Chasing you." He lifted his palm and continued to Nim, "As the police arrive, pull back. Avoid contact with 'em. But if you do get cornered, go meekly. We're the good guys. It's those nasty strangers inside the tower with the illegal plasma arcs they should be after. We're just tourists who spotted something peculiar while out for an evening stroll. You copy?"

There was a strained grin in Nim's voice. "Copy, sir."

"Keep an observer in sight of Tower Six. Report when the police arrive. Naismith out."

"Copy, sir. Nim out."

Mark emitted a m.u.f.fled moan, and surged forward to grab Miles by his jacket. "You idiot, what are you doing? Call the Dendarii back-order them to clear the Cetagandans out of Tower Seven! Or I will-"

He made to grab at Miles's wrist; Miles held him off and put his left hand behind his back.

"Ah-ah! Calm yourself. There's nothing I'd like more than a game of stunner tag with the Cetagandans, since we outnumber them-but they have plasma arcs. Plasma arcs have more than three times the range of a stunner. I don't ask my people to face that kind of tactical disadvantage without dire need."

"If those b.a.s.t.a.r.ds catch you they'll kill you. How much more dire does it have to be?"

"But Miles," said Ivan, looking up and down the corridor doubtfully, "didn't you just trap us in the center of a pincer movement?"

"No," Miles grinned, exhilarated, "I did not. Not while we own a cloak of invisibility. Come on!" He trotted back to the T intersection and turned right, back toward the Barrayaran-held Tower Six.

"No!" Mark balked. "The Barrayarans might kill you by accident, but they'll kill me on purpose!"

"The ones back there," Miles jerked his head over his shoulder, "would kill us both just to make sure. The Dagoola operation left the Cetagandans more peeved with Admiral Naismith than I think you have grasped. Come on."

Reluctantly, Mark followed, Ivan bringing up the rear.

Miles's heart pounded. He wished he felt half as confident as his grin to Ivan had suggested. But Mark must not be permitted to sense his doubt. A couple of hundred meters of blank synthacrete jerked past as he ran on tiptoe, trying to make as little noise as possible. If the Barrayarans had already worked their way this far down the tunnel- They came to the last pumping station, and still no sign of the lethal trouble ahead. Or behind. This pumping station was quiescent again. It would be another twelve hours to the next high tide. If no unexpected surges came downstream, it should stay shut down till then. Still, Miles was disinclined to leave it to chance, and from the way Ivan was shifting from foot to foot, watching him with growing alarm, he'd better be able to offer a guarantee.

He began looking over the control panels, raising one for a look within. Fortunately, it was much simpler than, say, the control nexus for a Jumpship propulsion chamber. A cut here, then there, should disable this pump without lighting up boards in the watchtower. He hoped. Not that anyone in the tower was likely to be paying much attention to their boards just this moment. Miles glanced up at Mark. "I need my knife, please."

Unwillingly, Mark handed the antique dagger over, and, at a look from Miles, its sheath as well. Miles used the point to pop the hair-fine wires. His guess as to which ones were which seemed correct; he tried to look like he'd known it all along. He did not hand the knife back when he was done.

He went to the pumping chamber hatch and opened it. No beeping this time. His gravitic grappler made an instant handle on the smooth inner surface. Last problem was that d.a.m.n manual locking bar. If some innocent-or not-so-innocent-came along and gave it a twirl-ah, no. The same model of tensor field lever, ally to the gravitic grappler, that Quinn had used to open the hatch to the ledge worked here. Miles blew a breath of relief through pursed lips. He returned to the control panel facing the corridor and slapped on his fisheye scan at the end of a row of dials. It blended in nicely.

He gestured toward the open hatch to the pumping chamber, as inviting as a coffin. "All right. Everybody in."

Ivan went white. "Oh, G.o.d, I was afraid that was what you had in mind." Mark did not look much more thrilled than Ivan.

Miles lowered his voice, softly persuasive. "Look, Ivan, I can't force you. You can head on up the corridor and take the chance that your uniform will keep you from getting your brains fried by somebody's nervous reflex. If you survive contact with Destang's. .h.i.t squad, you'll get arrested by the locals, which probably won't be fatal. But I'd rather you stuck with me." He lowered his voice still further. "And didn't leave me alone with him."

"Oh." Ivan blinked.

As Miles expected, this appeal for help had more impact than logic, demands, or cajolery. He added, "Look, it's just like being in a tactics room."

"It's just like being in a trap!"

"Have you ever been in a tactics room when the power's knocked out? They are traps. All that sense of command and control is an illusion. I'd rather be in the field." He smirked, and jerked his head toward his double. "Besides, don't you think Mark ought to get the chance to share your recent experience?"

"When you put it that way," growled Ivan, "it has a certain appeal."

Miles lowered himself into the pumping chamber first. He thought he could just hear distant footsteps scuffing in the corridor. Mark looked like he wanted to bolt, but with Ivan breathing down his neck he had little choice. Finally Ivan, with a gulp, dropped beside them. Miles keyed on his hand light; Ivan, the only one tall enough, shoved the heavy hatch shut. It was profoundly silent for a moment, but for their breathing, as they squatted knee to knee. Ivan's swollen, empurpled hands clenched and unclenched, sticky with sweat and blood. "At least y'know they can't hear us."

"Cozy," grunted Miles. "Pray our pursuers are as stupid as I was. I ran past this place twice." He opened the scanner case and set the receiver to project the north-and-south view of the still-empty corridor. There was a very faint draft in the chamber, Miles noted. Anything more would foretell a rush of water through the lines, and it would be time to bail out, Cetagandans or no Cetagandans.

"Now what?" said Mark thinly. He looked like he felt trapped indeed, sandwiched between the two Barrayarans.

Miles settled back against the slimy wet wall with a false air of ease. "Now we wait. Just like a tactics room. You spend a lot of time waiting in a tactics room. If you have a good imagination, it's-pure h.e.l.l." He keyed his wrist comm. "Nim?"

"Yo, sir. I was just about to call you." Nim's uneven voice sounded like he was running, or maybe crawling. "A police aircar just landed at Tower Seven. We're withdrawing through the park strip behind the Barrier. The observer reports the locals just entered Tower Six, too."

"Have you got anything off Quinn's wrist comm?"

"It still hasn't moved, sir."

"Has anyone made contact with Captain Galeni yet?"

"No, sir. Wasn't he with you?"

"He left about the time I lost Quinn. Last seen on the outside of the Tidal Barrier at about the midpoint. I'd sent him to look for another way in. Ah... report at once if anyone spots him."

"Yo, sir."

d.a.m.n, another worry. Had Galeni run into trouble, Cetagandan, Barrayaran, or local? Had he been betrayed by his own state of mind? Miles now wished he'd kept Galeni by him as heartily as he wished he'd kept Quinn. But they hadn't yet found Ivan then; Miles hardly could have done otherwise. He felt like a man trying to a.s.semble a jigsaw puzzle of live pieces, that moved and changed shape at random intervals with tiny malicious giggles. He unclenched his teeth. Mark was regarding him nervously; Ivan was hunkered down not paying much attention to anything, by the way he was biting his lips locked in an internal struggle with his new-won claustrophobia.

There was a movement in the somewhat distorted 180-degree scanner view of the corridor, a man loping silently around the curvature from the south end. Cetagandan point man, Miles guessed, though he wore civilian clothes. He had a stunner, not a plasma arc in his hand-apparently the Cetagandans were now aware that the locals were on the scene in too great force to silence by a convenient murder, and were now thinking of de-escalating, or at least decapitalizing, the Situation. The Cetagandan scouted up the corridor a few more meters, then vanished back the way he'd come.

A minute later, movement from the north: a pair of men tiptoeing along as quietly as a couple of gorillas of that size could move. One of them was the numbskull who'd managed to appear on a covert op still wearing his regulation Service boots. He too had exchanged his original weapon for a more demure stunner, though his companion still carried a lethal nerve disruptor. It looked like it really could be shaping up for a round of stunner tag. Ah, the stunner, weapon of choice for all uncertain situations, the one weapon with which you really could shoot first and ask questions later.

"Holster your nerve disrupter, that's right, good boy!" Miles murmured, as the second man too switched weapons. "Heads up, Ivan; this could be the best show well see all year."

Ivan glanced up, his absorbed uncertain smile trans.m.u.ting into something genuinely sardonic, more like the old Ivan. "Oh, s.h.i.t, Miles. Destang will have your nuts for engineering this."

"At present, Destang doesn't even know I'm involved. H'sh. Here we go."

The Cetagandan point man had returned. He made a come-on motion, and was leapfrogged by a second Cetagandan. On the other end of the corridor, beyond their view due to the curve, the remaining three Barrayarans came jogging. That accounted for all the Barrayarans that had been in the tower; any outer-perimeter backup was now cut off from them by the cordon of local police. The Barrayarans had apparently given up on their mysteriously vanished quarry and were in pull-out mode, hoping to exit via Tower Seven as quickly as possible without having to explain themselves to a bunch of unsympathetic Earthmen. The Cetagandans, who had actually witnessed the supposed Admiral Naismith run this way, were still in hunting array, though their rear guard was presumably closing up with the pressure from the locals coming on strong behind.

No sign of the rear guard yet; no sign of Quinn being dragged along as a prisoner. Miles didn't know whether to hope for that or not. It would be very nice to know she was still alive, but fiendishly difficult to extract her from the Cetagandans' clutches before the constables closed in. Least-cost scenario called for letting her be stunned/arrested with the mob of them, and reclaiming her from the police at their leisure-but suppose some Cetagandan goon decided in the heat of the final crunch that dead women couldn't talk? Miles jittered like a boiling kettle at the thought.

Perhaps he should have jacked up Ivan and Mark and attacked. The breakable leading the disabled and the unreliable in an a.s.sault on the unknown... no. But would he have done more, done less, for any other officer in his command? Was he so worried about his command logic being ambushed by his emotions that he was now erring in the opposite direction? That would be a betrayal of both Quinn and the Dendarii....

The lead Cetagandan darted into the line of sight of the lead Barrayaran. They both fired instantly, and dropped each other in a heap.

"Stunner reflexes," muttered Miles. "S' wonderful."

"My G.o.d," said Ivan, entranced to the point of wholly forgetting his hermetic enclosure, "it's just like the proton annihilating the anti-proton. Poof!"

The remaining Barrayarans, strung out along the corridor, flattened to the wall. The Cetagandan dropped to the floor and crawled to his downed comrade. A Barrayaran popped out into the corridor and blitzed him, the Cetagandan's return shot going wide. Two of the four Barrayarans hurried to the unconscious bodies of their mystery opponents. One prepared to offer covering fire, the other began checking them out, weapons, pockets, clothing. He naturally turned up no IDs. The baffled Barrayaran was just pulling off a shoe to dissect-Miles felt he would continue on to the body itself momentarily-when a distorted amplified voice began booming down the corridor from their rear. Miles could not quite make out the echo-splintered words, but the sense of it was clearly, "Here! Halt! What's all this, then?" One of the Barrayarans helped another load up the stunned one for a shoulder-carry; it had to have been the biggest man who'd been hit, Boots himself. They were close enough to the fisheye that Miles could make out the carrier's legs shake slightly as he straightened and began staggering south under his burden, two men taking the point before and the remaining one the rear guard behind.

The doomed little army had gone perhaps four steps when another pair of Cetagandans appeared around the south curve. One was firing his stunner back over his shoulder as he ran. His attention was so divided, he did not see his partner go down to the Barrayaran point men's stunner fire until he tripped over the sprawling body and fell headlong. He kept his clutch on his own stunner, turned his fall into a controlled roll, and snapped off return fire. One of the Barrayaran point men went down.

The Barrayaran rear guard leapfrogged forward around the burdened middle man and helped his partner zap the rolling Cetagandan, then ran forward with him, hugging the wall. Unfortunately, they overshot the arc of concealment at the same moment as a blast of ma.s.sed, unaimed stunner fire from beyond the curvature was clearing the corridor for some forward push from the unknowns-police combat team, Miles deduced both from the tactic and the fact that the Cetagandan had been firing in that direction. Men met energy wave with predictable results.

The remaining Barrayaran stood in the corridor bending under the weight of his unconscious comrade and cursing steadily, his eyes squeezed shut as if to shut out the sheer overwhelming embarra.s.sment of it all. When the police appeared behind him he clumped in a circle to face them and raised his hands in surrender as best he could, flipping his empty palms out and letting his stunner clatter to the floor.

Ivan's voice was suffused. "I can just see the vid call to Commodore Destang now. 'Uh, sir? We ran into this little problem. Will you come get me... ?'"

"He may prefer to desert," commented Miles. The two converging police squads came within a breath of repeating the mutual annihilation of their fleeing suspects, but managed to get their true ident.i.ties communicated just in time. Miles was almost disappointed. Still, nothing could go on forever; at some point the corridor would have become impa.s.sable due to the piles of bodies, and the havoc trail off according to the typical senescence curve of a biological system choked on its own waste. It was probably too much to ask that the police clear themselves, as well as the nine a.s.sa.s.sins, out of the path to escape. Miles was clearly in for another wait. Blast it.

Creaking, Miles stood, stretched, and leaned against the wall with folded arms. It had better not be too long a wait. As soon as the police combat squad called the all-clear, the bomb squad and Tidal Authority techs would appear and start going over every centimeter of the place. The discovery of Miles's little company was inevitable. But not lethal, as long as-Miles glanced down at Mark, hunkering at his feet-no one panicked.

Miles followed Mark's gaze to the scanner display, where the police were checking over the stunned bodies and scratching their heads. The captured Barrayaran was being properly surly and uninformative. As a covert ops agent he was conditioned to withstand torture and fast-penta too; there was little the London constables were likely to get out of him with the methods at their disposal, and he obviously knew it.

Mark shook his head, watching the chaos in the corridor. "Whose side are you on, anyway?"

"Haven't you been paying attention?" asked Miles. "This is all for you."

Mark looked up at him sharply, scowling. "Why?"

Why, indeed. Miles eyed the object of his fascination. He could see how a clone could get to be an obsession, and vice versa. He jerked up his chin in the habitual tic; apparently unconsciously, Mark did the same. Miles had heard weird tales of strange relationships between people and their clones. But then, anyone who deliberately went out and had a clone made must be kinky to start with. Far more interesting to have a child, preferably with a woman who was smarter, faster, and better-looking than oneself; then there was at least a chance for a bit of evolution in the clan. Miles scratched his wrist. Mark, after a moment, scratched his arm. Miles refrained from deliberately yawning. Better not start anything he couldn't stop.

So. He knew what Mark was. Maybe it was more important to realize what he was not. Mark was not a duplicate of Miles himself, despite Galen's best efforts. Was not even the brother of an only-child's dreams; Ivan, with whom Miles shared clan, friends, Barrayar, private memories of the ever-receding past, was a hundred times more his brother than Mark could ever be. It was just possible he had under-appreciated Ivan's merits. Botched beginnings could never be replayed, though they could be-Miles glanced down at his legs, seeing in his mind's eye the artificial bones within-repaired. Sometimes.

"Yeah, why?" Ivan put in at Miles's lengthening silence.

"What," piped Miles, "don't you like your new cousin? Where's your family feeling?"

"One of you is more than enough, thanks. Your Evil Twin here," Ivan made a horned-finger gesture, "is more than I can take. Besides, you both keep locking me in closets."

"Ah, but at least I called for volunteers."

"Yeah, I know that one. 'I want three volunteers, you, you, and you.' You used to bully me and your bodyguard's daughter around that way even before you were in the military, back when we were little kids. I remember."

"Born to command." Miles grinned briefly. Mark's brows lowered, as he apparently tried to imagine Miles as playground bully to the very large and healthy Ivan. "It's a mental trick," Miles informed him.

He studied Mark, who squatted uncomfortably, drawing his head down into his shoulders like a turtle against his gaze. Was this evil? Confusion, to be sure. Distortion of spirit as well as body-though Galen could have been only a little more awful as a child's mentor than Miles's own grandfather. But to be properly sociopathic one must be self-centered to an extreme degree, which did not seem to describe Mark; he had hardly been permitted to have a self at all. Maybe he was not self-centered enough. "Are you Evil?" Miles asked lightly.

"I'm a murderer, aren't I?" sneered Mark. "What more d'you want?"

"Was that murder? I thought I sensed some element of confusion."
