Star Trek 08 Read online

  Spock broke the silence. "Captain, there is an impostor aboard this ship."

  It was to be expected from Spock. Faith to the end—that was Spock. Kirk pulled his uniform collar away from his neck as though it were choking him. After a moment he went to the door of Sickbay's treatment room where McCoy had gone back to work on the battered Fisher. He was busy, of course; too busy with Fisher to look at him. But the prone Fisher looked at him from the sheeted table—and in his eyes there was open scorn.

  The intercom buzzed; and Scott said, "Captain, can we see you in the Transporter Room for a minute?"

  Kirk took the scalding memory of Fisher's look with him. If Spock hadn't silently joined him, he wondered if he'd have found the courage to respond to Scott's call. Had he, too, heard the interesting details of his Captain's recent activities? But Scott's total concern seemed to be the still defective Transporter. He looked up from the console as Kirk entered. "It's a complete breakdown, Captain." He turned his head to say to his technicians, "Continue circuit testing." The meek, doglike creature collected from the planet was lying beside the console. Scott pointed to it. "We beamed this animal up to the ship, sir, and . . ."

  "And what?" Kirk said.

  Scott paused. "The animal is here. But it's also over there in that specimen case."

  He left the console to go over to the case with Kirk and Spock. A fierce growl greeted them. Scott cautiously lifted the lid. The beast inside bared its teeth, its lips flecked with the foam of its fury. Scott hastily dropped the lid over its leap at them.

  "It appears to be the twin of the other animal," Spock said slowly. "Except for the difference in temperament, they might be one and the same."

  Scott had hurried back to the console to pick up the quiet creature. Stroking it, he said, "A few seconds after they sent this one up through the Transporter, that duplicate of it appeared on the platform. If this had happened to a man—it's some kind of opposite."

  The intentness on Kirk's face was naked. Scott went on. "One beast gentle like this—and one savage, wolfish, this one and that one—some kind of ferocious opposite. Captain, till we know what's gone wrong with the Transporter, we dare not use it to beam up the landing party!"

  "Oh, my God . . ."

  The whisper was wrenched from Kirk by the force of sudden revelation. It was no impostor who was loose on the Enterprise. What was loose on it was his own counterpart—the dark, brutish aspect of human nature which every mortal carries within him from birth to the grave. His Cain was roaming the Enterprise in a mindless, murderous search for a vengeance that would appease the bitterness of years of denial—the years it had spent as a prisoner of conscience, of duty, of responsibility. Somehow it had got free from its embodiment in him, and wearing his face, using his voice, wandering his ship, had found its release.

  He gradually became conscious of Spock's eyes. The Vulcan had taken the lamb-gentle animal into his arms. Something in the way he held it stilled the turmoil in Kirk's soul. He was able to speak.

  "Do you know what caused the animal to divide in two, Scotty?"

  "We think we do, sir. When Fisher came up, his clothes were splashed with some soft, yellowish stuff. He said it was ore. Some of it fell on the Transporter platform. When we scanned it, we found it contained unknown magnetic elements. Maybe it caused an overload. We can't tell—not yet."

  "Is the Transporter working at all?"

  "Yes, sir. But to use it to bring up the landing party—they might all be duplicated like you—" He caught himself. "Like the animal, Captain."

  So Scott had heard. "How long will it take to locate the trouble?"

  "Can't say, sir."

  Kirk fought for calm, for reason. "We can't just leave those four men down there. They'll freeze to death. At night that planet's temperature sinks to 250 degrees below zero."

  "We're doing everything we can, Captain!"

  Kirk looked at the Transporter platform. What was the secret it refused to divulge? He'd emerged from it whole, unsplit, a thousand times. Why not this last time? What had happened? When and how had he been divided in two halves like a one-celled organism reproducing itself? The whirling in his head was back once more. And the platform looked back at him, empty, its secret still withheld.

  Spock had come to stand beside him. "About this double of yours, Captain."

  Kirk started like a man aroused from nightmare. "Yes, we've got to find him. Search parties, Mr. Spock—we've got to organize search parties."

  "We can't risk killing it," Spock said. "We have no data—no way of knowing the effect of its death on you."

  So Spock understood. "Yes, that's right," Kirk said. "We don't know that—but the men must be armed. All men to be armed with phasers locked to the stun setting. He's to be taken without—if anyone fixes to kill, he won't die—it's not the way to get rid of him . . ."

  Spock noted the breaks between thoughts and words. They were disjointed, disorganized. No, there was no doubt. This Kirk was not the integrated, decisive Kirk he knew.

  "It will be difficult to order the search parties to capture a being who so closely resembles you, Captain."

  "Tell them—" Kirk looked at him helplessly. "I'd better make an announcement to the entire crew—tell them what's happened as well as I can. It's a good crew—they deserve to be told."

  "I must object, sir," Spock said. "You are the Captain of this ship. You cannot afford to appear vulnerable in the eyes of your crew. It is your damnable fate to have to seem perfect to them. I'm sorry, sir. Yet that is the fact. They lose their confidence in you—and you lose your command."

  Kirk pressed, his forehead between his hands. "I know that, Mr. Spock. Why did I forget it?" He turned away, then stopped without looking back. "If you see me slipping again, your order is to tell me so."

  "Yes, Captain."

  His back stiff, Kirk walked out of the Transporter Room. In the bridge he touched the back of his command chair before he took his position in it. Command—no weakness, no fault, no hesitation. Bracing himself for the front of perfection, he flicked on his intercom. "This is the Captain speaking. There is an impostor aboard this ship—a man who looks exactly like me and is pretending to be me. The man is dangerous. Utmost caution is to be observed. All crew members are to arm themselves. The impostor may be identified by scratches on his face."

  The message reached the double. It sat up quickly on Kirk's bed. "Repeat," came the voice from the intercom. "The impostor may be identified by scratches on his face. Search parties will report to Mr. Spock for assignment. All hand phasers will be set to stun force. The impostor is not to be injured. Repeat. The impostor is not to be injured."

  The double touched the scratches on its face. Then it got up to go to the mirror and stare at its reflection. "Impostor!" it muttered to itself. "I'm Kirk!" it shouted at Kirk's image on the intercom viewing screen. A gust of fury shook it. It seized a metal box from the dresser and hurled it at the screen. The sound of crashing glass frightened it. "I'm Kirk," it whimpered to its reflection in the mirror. The scratches showed red, unhealed. To examine them more closely, it pushed aside a jar of medicated cream. The loosened lid fell off. The double dug its fingers into the cream, looked once more at the scratches and began to rub the cream into them. It made them feel better. It also hid the weals. The double grunted with satisfaction. It was dabbing more of the concealing cream into the cuts when it heard running sounds from the corridor outside.

  When the sounds had gone, it unlocked the door. Moving out into the working area of Kirk's quarters, it slid its entrance panel half open. Wilson, carrying some Transporter equipment, was hurrying down the corridor.

  "Wilson!" the double called. "Come here!"

  Wilson came.

  "Give me your weapon belt!"

  "Yes, sir."

  As he handed over the belt, Wilson saw the smeared cream on its face. But his suspicion came too late. The double had the phaser out of the belt. It struck him on the jaw with its butt. When Wilson f
ell, it stooped to pound his jaw with the heavy butt. Then it dragged him into Kirk's cabin. The bloody phaser still in hand, it nodded to itself—and walked casually out into the corridor.

  Down on the planet's surface it was growing dark. Sulu and his three crewmen were gathering rocks to erect a wall against the rising wind. Frost had already whitened the dismal landscape as far as they could see.

  Over his communicator, Kirk said, "Mr. Sulu, how is the rock shelter coming?"

  "It's a compliment to these rocks, sir, to call them a shelter. It's down to 50 below zero now, Captain."

  They were not equipped with thermal clothing. It was hard to say, "Kirk out." He might better have said, "Kirk down and out." That was the truth. In his command chair, he had to steady himself against another attack of vertigo. "We've got to get those men up!" he said to Spock. But Spock was taking a report from one of his search parties. "Deck 5 Sections 2 and 3 completely covered now, sir. Result, negative. Proceeding to Sections 4 and 5."

  "Acknowledged," Spock said and flicked off his audio—but only to flick it on again to another intercom call.

  "Search party number eight, sir. Transporter technician Wilson has just been found crawling out of the Captain's cabin. He's been badly beaten. He says the impostor attacked him, called him by his name and took his phaser."

  "Get him to Sickbay," Spock said. "Then continue your search."

  "We must locate this—this opposite of mine before he—" Kirk broke off. "But how, Spock, how?"

  "It is apparent, sir, that it possesses your knowledge of the ship, its crew and devices. That being so, perhaps we can foresee its next move. Knowing how this ship is constructed, where would you go to elude a mass search, Captain?"

  For the first time since his disaster, Kirk spoke without hesitation. "The lower level. The Engineering deck. Let's go!"

  In the elevator Spock removed his phaser from his belt. Without looking at Kirk, he said, "I'm setting this, not to the kill cycle, but to the stun one, sir. What about your phaser?" Kirk took the hint; and Spock said, "This thing is dangerous. Don't you think we'll need some help if we find it?"

  The torture of indecision was back. Finally Kirk said, "No. If we find him, I don't want anyone else around but you." He had stepped out of the elevator when Spock called, "Captain!"

  Kirk turned.

  Spock said, "You ordered me to tell you . . ."

  "I said no, Mr. Spock. No one but you."

  The lower level of the Engineering deck held the vast complex that powered the Enterprise. It was a cavern of shadows, broken by glints of gleaming machinery, its passageways narrowing, widening, narrowing again to crisscross other passages. The droning hum of its huge nuclear energizers reverberated against its metal walls. Suddenly, as he rounded a dynamo, Spock realized he was alone. He turned to retrace his steps in hope of locating Kirk again.

  Kirk, unaware he had lost Spock, looked at the phaser he held at the ready. The sight of it repelled him. A suicide weapon was what it was. The life it would fell was part of his own. He replaced the phaser in his belt.

  And his Cain saw him do it. Crouched between two power generators, the double had heard his approaching footsteps Its features tensed with its curious mixture of fear and ferocity. Its phaser aimed, it moved away from its shelter for a full confrontation.

  Kirk stopped dead. As he recognized his own face in the Other's face, a chill passed over him. This nameless Thing belonged to him more utterly than any name his parents had given him. The two Kirks stared at each other in a kind of trance. Then, as though he were drawn by a power as unknown as it was powerful, Kirk stepped toward his double. It raised its phaser.

  Kirk spoke. His voice sounded strange in his own ears. It was solemn with the prophetic tone of a mystic suddenly endowed with an incontrovertible truth. "You must not hurt me," he said. "You must not kill me. You can live only as long as I live."

  Uncertainty flickered over the double's face; and Kirk, in a kind of dream, knew he was seeing the reflection of his own new uncertainty.

  Then the hesitation faded. "I don't need you!" the double said. "I don't have to believe what you say. So I can kill you!"

  Its finger was on the kill trigger. Leaping, the momentum of his leap lending force to his clenched fist, Spock lunged from behind the generator to land it, hammer-like, on the double's chin. It fell. Its phaser fired, the beam striking a machine unit behind Kirk. It flared into glow and collapsed.

  Spock looked down at the sprawled double. "I fear," he said, "that the ministrations of Dr. McCoy will be needed."

  The fear was well-founded. Consciousness was reluctant to return to the double. Each in his different way anxious, Kirk and Spock watched McCoy as he stooped over the still figure in its bed. McCoy worked silently. After a moment, Kirk went to the viewing screen. Turning it on to Engineering, he said, "What about those Transporter circuits, Scotty? They're all checked through now, aren't they?"

  "Yes, sir. And we thought we'd corrected the trouble. But now something else has gone wrong."

  "What?" Kirk demanded.

  "We don't know, sir. We're working on it. Is that all, Captain?"

  Once more Kirk was unable to rally either a yes or a no. There was an uncomfortable pause. Finally Scott said, "Then I'd better get back to work, sir."

  It would be darker on the planet. Kirk cried out, "Find out what's wrong, Scott! And fix it in God's name! Four human lives are depending on that Transporter!"

  Scott said stiffly, "We're doing our best, sir."

  Kirk leaned his forehead against the frame of the viewing screen. "I know, Scotty. You always do your best. Keep me posted, will you?"

  "Yes, sir." The voice had relaxed.

  Over at the bed, McCoy had completed his examination. "How is—he?" Kirk asked.

  "Pulse and blood pressure high," McCoy said. He glanced at Spock. "Probably due to that sock on the chin."

  "It was necessary, Doctor."

  "This—creature will be recovering consciousness soon. As I have no idea at all about its mental state, I can't give it a tranquilizer. I think we'd better bind it."

  He looked at Kirk for authorization. Kirk was suddenly oppressed by a sense of suffocation. The heavy tonnage of command responsibility seemed to be crushing him. He shook his head to try and clear it of the dizziness. "Yes," he said, "all right. I just wish someone would tell me what's the matter with me."

  "You are losing the power of decision, Captain," Spock said.

  "What?"

  McCoy was busy binding the double but not so busily that he couldn't direct a glare at Spock. But the Vulcan continued, cool and unruffled. "Judging from my observations," he said, "you are rapidly losing your capacity for action. There's hesitation in time of crises—loss of perception. Captain, you refuse to defend yourself. You refused to demand adequate assistance when we went down to the Engineering level whereas you should have placed yourself in guarded isolation until the impostor was captured." He paused. "You have dismissed men for less hesitation, less passivity in the face of danger."

  "Make your point, Spock!" shouted McCoy.

  "Point?"

  "You have one, I presume," McCoy said.

  "I am analyzing, Doctor; not point-making."

  "It's the Captain's guts you're analyzing! Are you aware of that, Mr. Spock?"

  "Vituperation, Doctor?"

  Composed, unmoved, Spock went on. "The dichotomies inherent in the human mind are multiple," he said. "The problem of command, for instance, highly pertinent in this case. Command is a balance between positive and negative energies—an equilibrium of the forces generated by each of these energies. The proof?"

  He turned to Kirk. "Your negative energy was removed from you by that duplication process. Thus, the power of command has begun to fail you. Things remaining as they are, how long can you continue to function as Captain of this ship? Finally unable to decide anything at all, will you . . ."

  McCoy broke in. "Jim, give him a command! Tell h
im to get lost!"

  "If I seem emotionally insensitive to the agony of your ordeal, Captain, please understand. It's the way I am."

  "That's for damned sure!" yelled McCoy.

  "Gentlemen," Kirk said. In the end, always in the end, one's pain remained a private matter. The scene, however dismal, was always enacted alone. He smiled wryly at them. "I may be losing my ability to command but it hasn't entirely disappeared. Until it does, you will both kindly knock it off."

  The intercom on McCoy's desk whirred. Kirk flicked it on. "Kirk here."

  "Engineering, sir. We've just located that new trouble with the Transporter. Its Ionizer Unit has been mangled. Looks as if a phaser beam had hit it."

  The double's phaser beam had hit it, the double, that separated part of himself. If his crewmen died their lonely death on the subarctic planet beneath him, it would be he, Kirk, their trusted Captain who had killed them.

  He got up to walk to the door. "If I'm needed," he said, "I'll be in the Briefing Room."

  They had lit a fire down on the planet. Black night was spreading toward them from its horizon. And the stealthy fronds of frost were creeping over the rocks of the rock shelter where the abandoned crewmen huddled together for warmth. Sum, his lips cracked and sore, had to hold his hands over the fire before his fingers could manipulate his communicator. "Can you give us a status report, Enterprise? It's fallen to 90 degrees below zero down here."

  "This is the Captain, Mr. Sura. We have located the trouble. It shouldn't be much longer."

  "Think you could rig up a cord, sir, and lower us down a pot of coffee?"

  "I'll see what I can do about that," Kirk said.

  "Rice wine will do, sir, if you're short of coffee."

  "I'll check the commissariat for rice wine, Mr. Sulu." And once more it had to be "Kirk out."

  He watched his hand reach out to the intercom button. He was afraid to call Scott. He pressed the button. "That mangled unit, Scotty. Status report."

  "Nothing much of it left, sir."
