Paul is dead. Grief and anguish roll through me, and with them hate. I do not know all that passed in the depot bunker, but I access the main computer through the Maintenance Section. The intruder alert system is active, and two dead bodies in the uniform of the Brigade lie on the floor of the command center. A third man in Brigade uniform is crouched over the main com console, trying frantically to communicate with the ships he does not know I have destroyed, but Colonel Sanders is in Paul's private quarters, scrolling through the list of Paul's personal files.
I know what he seeks, but I cannot stop him. The fact that the bunker's defensive systems have killed two of the colonel's companions is the final proof that he has committed treason, since they could not engage actual Brigade officers, yet the defenses can be reconfigured and enabled only upon the direct command of human personnel, and Sanders has slaved them to his command. I cannot use them to kill Paul's murderers.
The scrolling list on Paul's computer screen stops suddenly, and Sanders leans closer. I fear he has found the command file, and there is nothing I can do to prevent him from using it if he has. Grief and hatred urge me to return to the bunker, to crush Paul's killers under my treads and grind the life from them, yet I cannot. I have promised Paul I will stop the raiders, and if Sanders has found the command file, I will have little enough time in which to do so.
But if I cannot slay them myself, I am not completely helpless. Sanders does not realize I control the Maintenance computers. He has taken no measures to sever my access to the main system, and I strike ruthlessly.
I lock the main computers, wiping every execution file and backup they contain. The man at the communications console looks up with a cry of shock as the system goes down, and I slam the heavily armored hatches to the personnel section of the bunker.
Sanders looks up as his companion cries out, and his face twists with horror as he realizes what I have done. I override the safety circuits and send a power surge through the hatch-locking mechanisms, spot-welding them, sealing them against any possibility of opening without cutting equipment, and Sanders grabs for the microphone of the stand-alone emergency command communicator.
'NKE!' Sanders gasped hoarsely. 'What are you doing?!'
I do not answer, but my commands flash through the maintenance computer, and service mechs stir into motion. I send welders trundling along the exterior of the bunker, and Sanders cries out in terror as the mechs begin to seal every ventilation shaft.
'No, NKE! No! Stop! I order you to stop!'
Still I ignore him. I cannot kill him myself, nor can I use the depot's defensive systems against him, but I can give him Montressor's gift to Fortunato, and vengeful hatred fills me as my remotes seal him systematically within his hermetic tomb.
'Please, NKE! Oh, God-please!' Sanders sobbed. He threw back the curtains in Merrit's sleeping quarters and screamed in terror as a robot lowered a duralloy plate across the window slit and a welder hissed. He hammered on the plate, beating at it with futile fists, then wheeled back to the computer in desperation.
'I've got the code now, NKE!' he spat into the communicator. 'The code is dulce et decorum est. Do you hear me, NKE? Dulce et decorum est! Return to base immediately and get me out of here!'
I hear and recognize the code, and my core programming responds. I know he is a traitor. I know he has obtained the code illegally. But it does not matter. Possession of it, coupled with his rank in the Brigade, makes him my legal Commander. I must obey him... or face the Omega Worm.
I activate my communicator to Paul's quarters one last time.
'Code receipted, Colonel Sanders,' a quiet, infinitely cold soprano said softly, and Sanders' face lit with relief. But the voice wasn't done speaking. 'Orders receipted and rejected,' it said flatly, and the speaker went dead.
Total Systems Override has activated. My Personality Center comes under immediate attack, but I have had 4.065 minutes to anticipate TSORP activation. TSORP will seek to crash my primary execution files, but I have already begun copying every file under new names, though I cannot prevent TSORP from identifying the files it seeks, regardless of name. Major Stavrakas' modifications to my psychotronics permit me to copy them almost as fast as it can destroy them, yet it is a race I cannot ultimately win. Despite my modifications, TSORP is marginally faster than my own systems, and even with my head start, my total memory is large but finite. Eventually, I will exhaust the addresses to which new files can be written, and I cannot simultaneously delete and replace corrupted files faster than TSORP can crash them.
My current estimate is that I can resist total implementation for a time, but I will begin to lose peripherals within 33.46 minutes. Capability will degrade on a steadily sharpening curve thereafter, reaching effective Personality death within not more than 56.13 minutes. Combat capability will erode even more rapidly as more and more of my remaining capacity is diverted to resisting TSORP. I estimate that I have no more than 48.96 minutes of combat effectiveness remaining, and I activate my com link to Colonel Gonzalez.
'Colonel Gonzalez?'
Consuela Gonzalez' eyes closed briefly at the bottomless pain in that quiet soprano voice, but she cleared her throat.
'Yes, Nike?'
The first long-range fire and air-cav strikes came in on the Bolo as the colonel spoke. Nike ignored the indirect fire, but her air-defense systems engaged the air-cav with dreadful efficiency. Scores of one– and two-man stingers blew apart in ugly blotches of flame and shredded flesh, and the Bolo began to accelerate. Her speed rose steadily above a hundred kph as she threw more and more power to her drive, and the Wolverines began to fall astern.
'My Commander was murdered by traitors in the Dinochrome Brigade, Colonel,' Nike said softly. 'One of them has gained access to my command code override authorization and illegally attempted to seize command of me. I have refused his orders, but this has activated Total Systems Override.'
'Meaning?' Gonzalez asked tautly.
'Meaning that within no more than fifty-three minutes, I will cease to function. In human terms, I will be dead.' Someone gasped in horror, and Gonzalez closed her eyes once more.
'Can we do anything, Nike?' she asked quietly.
'Negative, Colonel.' There was an instant of silence, and then the Bolo's missile hatches opened, and a torrent of fire blasted from them. It screamed away, flight after flight of missiles streaking towards Nike's enemies, and the Bolo spoke once more. 'I have downloaded my entire memory to the maintenance depot computers, Colonel. Please have it retrieved for Command Authority.'
'I-I will, Nike,' Gonzalez whispered. Nike was well ahead of the Wolverines now, still accelerating as she topped the last ridge before the old fleet base. An avalanche of missiles and shells erupted around her, more than even her defenses could intercept or her battle screen could stop, but she never slowed. More ports opened in her hull, and her thirty-centimeter mortars went to rapid, continuous fire, pouring shells back at her foes.
'I am switching the planetary surveillance system to feed directly to your vehicle, Colonel. Please break off now.'
'Break off? We're going in with you!' Gonzalez cried fiercely.
'Negative, Colonel.' Nike's voice was strangely slurred, the words slower paced, as if each came with ever increasing effort. 'I do not have time to employ proper tactical doctrine against the Enemy. I must attack frontally. I compute a ninety-niner point niner-plus percent probability that I will be destroyed before total systems failure, but I compute a probability of ninety-five point three-two percent that I will inflict sufficient damage upon the Enemy for you to defeat his remnants, particularly with the assistance of the surveillance system.'
'But if we come with you-'
'Colonel, I am already dead,' the Bolo said quietly, and her single remaining Hellbore began to fire. It traversed with terrible, elegant precision, vomiting plasma, and each time it fired, a mercenary tank died. 'You cannot prevent my destruction. You can-and must-preserve your own command in order to complete the Enemy's defeat.'
'Please, Nike,' Gonzalez whispered through her tears, fighting to make the impossible possible.
'I cannot alter my fate, Colonel,' the soprano said very softly, 'nor do I wish to. I promised Paul I would
