"What is that?" I asked, feeling choked.
"Logic scum," Festina said. "Chunks of the ship’s data get encoded in organic molecules: DNA, long chain polymers, stuff like that — then all those chemicals are packaged into a single living cell. A data bacterium. The only problem is that bacteria can be killed."
She nodded toward the red powder on the floor. "That’s a chemical called Modig — a bio-poison that rips data bacteria to shit. This foam is the result: a slurry of bacterial corpses. All that’s left of the logic circuits."
Festina booted another kick into the left access door, cracking it off its bottom hinge. The impact splashed back a flurry of foam that spattered onto the leg of her trousers. She retreated a quick step and shook her foot, endeavoring to throw off every speck of foam clinging to her pants. As she did so, she said, "Oar, break that panel off. Try to stay clear of the scum."
"Yes, Festina." I pulled down the sleeve of my jacket so it completely covered my hand, then slammed my forearm against the remaining hinge of the access door. The hinge was flimsy indeed — it broke with a ‹PING›, and the door flew several paces before clattering to the tiles. Sergeant Aarhus ran after it; snatching it up, he hurried back to the computer and began using the panel to shovel foam onto the floor. Although he still wore his armor, Aarhus flinched whenever the froth splashed against him.
"Is logic scum poison too?" I whispered to Festina.
"Not the scum itself," my friend said. "But mixed in with the dead bacteria are traces of the Modig that killed them; and Modig is an utter bitch."
She glanced toward the woman in brown… particularly at the red dust on the woman’s hands. The woman was looking at the dust too: lifting her hands in front of her eyes, staring at her crimson fingers. Bits of gray foam had begun to bubble from beneath the woman’s fingernails — the same type of foam that was flooding from the computer, only this came from the woman herself. Festina opened her mouth as if to tell the woman something; then she shook her head. Turning away sharply, she headed in the oppositedirection, toward a console at the far end of the computer bank.
The Pollisand Follows His Trade
"The circuits are shot," Aarhus said, still scooping foam out of the computer. "Electronics as well as biologicals. Must have been a feedback surge." He glanced at a label on top of the machine. "Unit 4A51," he told Festina. "What is it? Navigation? Engine control?"
Festina had reached the console. She bent over it, tapping buttons. "4A51 is the primary security module. Damn… the readout says it’s in master mode."
Aarhus growled. "How the hell could she put it in master? Only the captain and the XO know the privileged access codes."
"Not true," Festina told him. "Admirals on the High Council know the codes too… or backdoors to get around the usual security. Obviously, some admiral ordered this woman to sabotage us, and gave her the codes to do it."
"But why did she follow such an order?" said a nasal voice. "And why so incompetently?"
We had forgotten about the Pollisand. He stood exactly where we had first seen him… but by some disquieting coincidence, that position was conveniently out of the way of everything we had been doing. He had not been in the flight path of the panel I knocked across the room, nor Aarhus’s rush to grab the panel, nor Festina’s route to the control console. When the woman in brown stumbled back from the foam, the white headless creature had been just a bit to one side of her retreat.
As I looked around, I could not see a single other spot he could have settled himself without getting in the way of at least one of us. Yet he had put himself in that special location before we entered the room.
Deep in the creature’s neck, one of his glowing eyes vanished for a moment — a Pollisandish wink. It was almost as if he were acknowledging the thought which had silently gone through my head… but I did not want to believe that, so I put it out of my mind.
Meanwhile, the Pollisand’s words had drawn Festina’s attention. She whirled on him, shouting, "What are you doing here? What do you want?"
"I want answers to my questions," he said, "but do I get them? Not bloody likely. Nobody ever has time to talk: it’s always Crisis this and Emergency that, with everyone far too busy for civilized discourse. Bet it would be different if I had a goddamned head — but no, you’re all so superior, constantly wearing hats and flaunting your peripheral vision, never mind how it eats me up inside, condemned forever to be cranially disadvantaged…"
He lifted his large foot and pointed toward the woman in brown, whose hands were now covered in foam that bubbled from her own skin. "Speaking of being eaten up inside," the Pollisand said, "this woman has thirty grams of Modig ripping her apart. You might want to deal with that before she dies of shock."
"Damn!" Festina said. Raising her voice, she called, "Ship-soul, attend. Tell Dr. Havel we have a severe case of Modig poisoning in the main computer room."
"Aye-aye, Admiral," a metallic voice answered from the ceiling.
"Hurray," Aarhus muttered, "the computer is still on-line."
"Don’t celebrate too soon," the Pollisand told him.
The sergeant winced. "Why?"
"You’ll see in seventy-two seconds."
"God damn it," Festina said, "quit being a know-it-all, and tell us something useful. What did this woman do, and how can we stop it?"
"You can’t stop it," the Pollisand replied. "And what this woman did — by the way, her name is Zuni, if you care, which you don’t, or you wouldn’t need a complete stranger to introduce you to someone who’s been under your command since the day you inherited this ship — but no, let’s not waste time on civilities which are only the bedrock of society, what this woman, Zuni, that’s still her name, even if you don’t care about it, did…" The Pollisand took a breath. "What Zuni did was write a program she believed would let her override the captain’s commands."
"Which explains why she put the system in master mode," Aarhus said. "If her program worked, she could set our course straight back to New Earth… and prevent anyone from changing it."
"But the program didn’t work," the Pollisand told him. "Zuni didn’t test it first: she just wrote it and ran it. Which clearly shows that possessing a head isn’t the same as using it. (Not that I’m bitter.) What kind of programmer is so divorced from reality she thinks she’ll get complex software right the first time? Especially when she’s hacking the ship’s most important security settings."
"Look," Festina interrupted, "we’ll discuss Zuni another time. Just tell us what the program did."
"It went out of control," the Pollisand said. "Romped off on its own, overwriting basic system code. She tried to rein it in from the console, but it had already stomped part of its own control settings; that’s when she popped open a tube of Modig powder."
"Why was she carrying a vile red poison?" I asked. "Was she a secret assassin?"
"No," Festina answered, "it’s navy policy to have some Modig available precisely for situations where you’ve got a runaway computer and can’t shut it down."
"It is better to turn off the power switch," I told her, "or to adjust the machine’s mechanisms with an ax."
"Zuni didn’t have an ax," the Pollisand said, "and the way to turn off a power switch on this ship is to ask the computer to do it — which doesn’t work if the computer is already fucked up the snout. Anyway, Modig is standard issue for last-ditch emergencies, and Zuni had been immunized against tiny exposures… but she should have known better than to scoop it up with her hands and smear it into the circuits. No immunization can protect a human from that much contact. Why would my poor Zuni do such a thing?"
