Then the bridge screamer went off.
“What the — get that!” Brad’s coffee went flying as he scrambled for the comm terminal. Mary jolted upright, whey-faced.
“Got it. That’s not traffic—”
“Hello, this is flight Echo Gold Nine Zero responding to broadcast squawk from, ah, Delta X-ray Zeus Seven, we have handshake. What’s the—”
“Something flaky here, boss—”
Red flashing lights blinked on the conference circuit. There was a thirty-second delay while they waited tensely for a reply.
“Echo Gold Nine Zero this is Delta X-ray Zeus Seven, emergency relay service. Admiralty signal blue four, authentication follows message. This is a systemwide military emergency. Moscow is under quarantine — the whole system is under lockdown, no exceptions. Evacuate immediately. I emphasize, get your kernel spun up and get out of here immediately! Please acknowledge.”
Brad flushed, furious. “This is some sort of fucking joke!” He waved off the authentication code and punched in the waypoint series for Moscow. “When I find the asshole—”
“Brad. Come here.” He looked round sharply. Mary was leaning over the repeater from Wang’s crow’s nest downstairs. She looked sick.
“What is it?”
“Here.” She pointed to a plot that had just shown up. Taxis Pride was a fleet auxiliary, liable for mobilization in event of war: it carried near-military-grade passive sensors. “Gamma plot, classic proton-antiproton curve, about two AUs out. It’s redshifting on us. I got a fix on that relay service buoy, Brad: it’s at the origin point for that … burn.”
“Shit!” The screen swam in front of Brad’s eyes. All of a sudden he remembered what it was like when he was nine, when his father told him his dog had died. “Shit!” Positronium was an unstable intermediate created during some matter-antimatter reactions. Redshifted, it was moving away from the reference frame of the observer at some fraction of the speed of light. Out from the star, it could mean only one thing — slower-than-light antimatter rockets, relativistic retaliation bombers cranking up for a kamikaze run on someone’s home world. “They’ve launched. They’ve fucking launched the deterrent fleet!”
They were a long-practiced team: he didn’t have to tell Mary what to do. She was already bringing back up the gravitational potential maps he’d need for the jump. Brad canceled his half-planned course and fed in the return journey jump coordinates. “Hello Delta X-ray Zeus Seven, this is flight Echo Gold Nine Zero acknowledging. We are preparing to return to Iceland Seven soonest. Can you clarify the situation for us. Other shipping may be in the queue and need warning off. Do you need assistance? Over.” Then he got on the blower to Liz, down in kernel monitoring, explaining to her that, no, this wasn’t a joke, and yes, he was going to overrun the drive maintenance cycle, and yes, it was going to put the Pride in the dock for a month and there was a good reason for it all — “Echo Gold Nine Zero, departure cleared. This is Delta X-ray Zeus Seven, relaying through NavServ buoy six-nine-three via causal channel. Situation as follows: inner system exterminated by surprise attack using weapons of mass destruction approximately two-seven-zero minutes ago absolute time. Your range three-six-zero light minutes considered marginal for survivaclass="underline" the star’s gone. We’re assuming one hundred percent fatalities on Moscow, repeat, one hundred percent. V-force has launched, but we’ve got no idea who did it. As of two hours ago, Moscow system is under complete interdict. Wait—” for a moment the steady voice wavered. “Oh. Oh my! That felt weird.” A pause. “Echo Gold Nine Zero, we’ve just taken a core radiation pulse. Funny, two kilometers of rock shielding outside us. Ah, shit. Off the scale. Neutrinos, has to be. Echo Gold Nine Zero, this is Delta X-ray Zeus Seven, there’s — I don’t think there’s anything you can do for us. Get the hell out while you still can — warn everybody off. Signing off now.”
Brad stared at the comm status display without seeing it. Then he mashed his palm down on the general channel glyph. “Crew, captain speaking.” He glanced at Mary and saw her staring back at him. Waiting. “We have a situation. Change of plan.” Glancing down at his panel he blinked and dragged the urgent course correction into the flight sequence. “We’re not going home. Ever.” Taxis Pride was the first ship to leave Moscow system after the explosion. Another two ships made it out, one of them badly damaged by jumping into the tail of the shock wave. Word of the explosion filtered out: several freighters were saved from jumping into a fiery grave by dint of a massive and well-coordinated emergency alert. Over the next few weeks, the inhabitants of the Iceland Seven refinery station — a mere eight light months from Moscow — were evacuated to Shenjen Principality, and as the shock wave rolled outward, more vulnerable habitats were evacuated in turn. The nearest populated planetary system, Septagon Central, was far enough away to be saved by the heavy radiation shielding on its orbital republics. Meanwhile, years would pass before another starship visited the radiation-scarred corpse of Moscow system.
IMPACT: T plus 1392 days, 18 hours, 11 minutes
“What’s your finding?” demanded the Captain.
The three dogs grinned at him from their positions around his cramped day cabin. One of them bent to lick at a patch of blue foam sticking to its left hind leg. The foam hissed and smoked where saliva ran. “There is nothing to report on the first incident, the customs officer. We regret to inform you that he must be classed as missing, presumed dead, unless we subsequently learn that he boarded one of the other ships. The second incident was a juvenile delinquent escapade committed by an asocial teenager. No trusted subsystems appear to have been compromised. I have no direct access to the cargo carried in the security zone, but you have assured me yourself that none of the black manifest packages are missing. The recorded history of the delinquent is consistent with this event, as is her subsequent behavior, and a search of the documentation corpus pertaining to socialization of juvenile adults in prewar New Moscow society indicates that territorial escapades of this kind are a not-infrequent response to environmental stress.”
“Why did she get in there in the first place?” Mannheim leaned forward, glaring at the lead hellhound with a mixture of anxiety and distrust. “I thought you were supposed to be guarding—”
“In my judgment her actions are compatible with typical human adolescent dysfunctional behavior. This search-and-rescue security unit is not authorized to use lethal force to protect bonded cargo, Captain. A secondary consideration was that her absence had been noticed by familial parties and formally reported after she was officially transferred aboard the evacuation ferry. Remanding the delinquent into the care of her parents, with subsequent monitoring and supervision for the duration of the voyage, will prevent repetition and will not invite further attention.”
The dog that had been talking jerked its head pompously. One of its fellows padded over and sniffed at its left ear. Mannheim watched them nervously. Police dogs, incredibly expensive units bought from some out-system high-tech polity, programmed for loyalty to the regime: he’d never even seen any before this voyage, was startled to learn the government owned any, much less that they’d see fit to deploy them on something as mundane as an evacuation run. And then, one of them claimed to be a Foreign Office dog, loaded onto his ship along with orders — sealed orders handwritten on paper for his eyes only — to be turned loose on the ship. Uplifted dogs designed for security and search-and-rescue, a pack hiding one member capable of killing. Exotic sapient weapons. “Did you carry out your mission?”
