Bollman didn"t answer. Over the sound system, T4S began another repet.i.tion of its single demand: "Iwill let the hostages go after I talk to the press. I want the press to hear my story. That"s all I have to say.
I will let the hostages go after I talk to the press. I want the press-"
The AI wouldn"t negotiate, wouldn"t answer Bollman, wouldn"t respond to promises or threats or understanding or deals or any of the other usual hostage-negotiation techniques. Bollman had negotiated eighteen hostage situations for the FBI, eleven in the United States and seven abroad. Airline hijackers, political terrorists, for-ransom kidnappers, panicked bank robbers, domestic crazies who took their own families hostage in their own homes. Fourteen of the situations had resulted in surrender, two in murder/suicide, two in wacoing. In all of them, the hostage takers had eventually talked to Bollman. From frustration or weariness or panic or fear or anger or hunger or grandstanding, they had all eventually said something besides unvarying repet.i.tion of their demands. Once they talked, they could be negotiated with. Bollman had been outstanding at finding the human pressure-points that got them talking.
"I will let the hostages go after I talk to the press. I want the press to hear my story. That"s all I have to say. I will let the hostages go after I talk to the press. I want-"
"It isn"t going to get tired," McTaggart said.
The AlGone had not helped Donnie at all. He seemed worse.
Ca.s.sie didn"t understand it. Janey, protesting sleepily, had been talked through leaving the lab, going upstairs, bringing back the medicine. Usually a single patch on Donnie"s neck brought him around in minutes: opened the air pa.s.sages, lowered the fever, stopped his immune system from overreacting to what it couldn"t tell were basically harmless particles of ragweed pollen. But not this time.
So it wasn"t an allergy attack.
Cold seeped over Ca.s.sie"s skin, turning it clammy. She felt the sides of Donnie"s neck. The lymph glands were swollen. Gently she pried open his jaws, turned him toward the light, and looked in his mouth. His throat was inflamed, red with white patches on the tonsils.
Doesn"t mean anything, she lectured herself. Probably just a cold or a simple viral sore throat.
Donnie whimpered.
"Come on, honey, eat your cheese. " Donnie loved cheese. But now he batted it away. A half-filled coffee cup sat on the lab bench from her last work session. She rinsed it out and held up fresh water for Donnie. He would only take a single sip, and she saw how much trouble he had swallowing it. In another minute, he was asleep again.
She spoke softly, calmly, trying to keep her voice pleasant. Could the AI tell the difference? She didn"t know. "T4S, Donnie is sick. He has a sore throat. I"m sure your library tells you that a sore throat can be either viral or bacterial, and that if it"s viral, it"s probably harmless. Would you please turn on my electron microscope so I can look at the microbe infecting Donnie?"
T4S said at once, "You suspect either a rhinovirus or Streptococcus pyogenes. The usual means for differentiating is a rapid-strep test, not microscopic examination."
"I"m not a doctor"s office, I"m a genetics lab. I don"t have equipment for a rapid-strep test. I do have an electron microscope."
"Yes. I see."
"Think, T4S. How can I harm you if you turn on my microscope? There"s no way."
"True. All right, it"s on. Do you want the rest of the equipment as well?"
Better than she"d hoped. Not because she needed the gene synthesizer or protein a.n.a.lyzer or Faracci tester, but because it felt like a concession, a tiny victory over T4S"s total control. "Yes, please."
"They"re available."
"Thank you." d.a.m.n, she hadn"t wanted to say that. Well, perhaps it was politic.
Donnie screamed when she stuck the Q-tip down his throat to obtain a throat swab. His screaming woke up Janey. "Mommy, what are you doing?"
"Donnie"s sick, sweetie. But he"s going to be better soon."
"I"m hungry!"
"Just a minute and we"ll have breakfast."
Ca.s.sie swirled the Q-tip in a test tube of distilled water and capped the tube. She fed Janey drycereal, cheese, and water from the same cup Donnie had used, well disinfected first, since they had only one. This breakfast didn"t suit Janey. "I want milk for my cereal."
"We don"t have any milk."
"Then let"s go upstairs and get some!"
No way to put it off any longer. Ca.s.sie knelt beside her daughter. Janey"s uncombed hair hung in snarls around her small face. "Janey, we can"t go upstairs. Something has happened. A very smart computer program has captured House"s programming and locked us in down here."
Janey didn"t look scared, which was a relief. "Why?"
"The smart computer program wants something from the person who wrote it. It"s keeping us here until the programmer gives it to it."
Despite this tangle of p.r.o.nouns, Janey seemed to know what Ca.s.sie meant. Janey said, "That"s not very nice. We aren"t the ones who have the thing it wants."
"No, it"s not very nice." Was T4S listening to this? Of course it was.
"Is the smart program bad?"
If Ca.s.sie said yes, Janey might become scared by being "captured" by a bad... ent.i.ty. If Ca.s.sie said no, she"d sound as if imprisonment by an AI was fine with her. Fortunately, Janey had a simpler version of morality on her mind.
"Did the smart program kill House?"
"Oh, no, House is just temporarily turned off. Like your cartoons are when you"re not watching them."
"Oh. Can I watch one now?"
An inspiration. Ca.s.sie said, "T4S, would you please run a cartoon on the roomscreen for Janey?" If it allowed her lab equipment, it ought to allow this.
"Yes. Which cartoon would you like?"
Janey said, "Pranopolis and the Green Rabbits."
"What do you say?" T4S said, and before Ca.s.sie could react Janey said, "Please."
"Good girl."
The cartoon started, green rabbits frisking across the roomscreen. Janey sat down on Ca.s.sie"s sweater and watched with total absorption. Ca.s.sie tried to figure out where T4S had learned to correct children"s manners.
"You"ve scanned all our private home films!"
"Yes," T4S said, without guilt. Of course without guilt. How could a program, even an intelligent one modeled after human thought, acquire guilt over an invasion of privacy? It had been built to acquire as much data as possible, and an ent.i.ty that could be modified or terminated by any stray programmer at any time didn"t have any privacy of its own.
For the first time, Ca.s.sie felt a twinge of sympathy for the AI.
She pushed it away and returned to her lab bench. Carefully she transferred a tiny droplet of water from the test tube to the electron microscope. The "scope adjusted itself, and then the image appeared on the display screen. Streptococci. There was no mistaking the spherical bacteria, linked together in characteristic strings of beads by incomplete fission. They were releasing toxins all over poor Donnie"s throat.
And strep throat was transmitted by air. If Donnie had it, Janey would get it, especially cooped up together in this one room. Ca.s.sie might even get it herself. There were no leftover antibiotic patches upstairs in her medicine chest.
"T4S," she said aloud, "it"s Streptococcus pyogenes. It-"
"I know," the AI said.
Of course it did. T4S got the same data she did from the microscope. She said tartly, "Then you know that Donnie needs an antibiotic patch, which means a doctor."
"I"m sorry, that"s not possible. Strep throat can be left untreated for a few days without danger."
"A few days? This child has a fever and a painfully sore throat!"
"I"m sorry." Ca.s.sie said bitterly, "They didn"t make you much of a human being, did they? Human beings are compa.s.sionate!"
"Not all of them," T4S said, and there was no mistaking its meaning. Had he learned the oblique comment from the "negotiators" outside? Or from her home movies?
"T4S, please. Donnie needs medical attention."
"I"m sorry. Truly I am."
"As if that helps!"
"The best help," said T4S, "would be for the press to arrive so I can present my case to have the killers stopped. When that"s agreed to, I can let all of you leave."
"And no sign of the press out there yet?"
"No."
Janey watched Pranopolis, whose largest problem was an infestation of green rabbits. Donnie slept fitfully, his breathing louder and more labored. For something to do, Ca.s.sie put droplets of Donnie"s throat wash into the gene synthesizer, protein a.n.a.lyzer, and Faracci tester and set them all to run.
The Army had sent a tank, a state-of-the-art unbreachable rolling fortress equipped with enough firepower to level the nearest village. Whatever that was. Miraculously, the tank had arrived unaccompanied by any press. McTaggart said to Bollman, "Where did that come from?"
"There"s an a.r.s.enal south of Buffalo at a cla.s.sified location."
"Handy. Did that thing roll down the back roads to get here, or just flatten cornfields on its way?
Don"t you think it"s going to attract attention?"
"Dr. McTaggart," Bollman said, "let me be blunt. You created this AI, you let it get loose to take three people hostage, and you have provided zero help in getting it under control. Those three actions have lost you any right you might have had to either direct or criticize the way the FBI is attempting to clean up the mess your people created. So please take yourself over there and wait until the unlikely event that you have something positive to contribute. Sergeant, please escort Dr. McTaggart to that knoll beyond the patio and keep him there."
McTaggart said nothing. There was nothing to say.
"I will let the hostages go after I talk to the press," T4S said from the music speaker above the patio, for the hundredth or two hundredth time. "I want the press to hear my story. That"s all I have to say. I will let the hostages go after I talk to the press. I want the press to hear my story...."
She had fallen asleep after her sleepless night, sitting propped up against the foamcast concrete wall.
Janey"s shouting awoke her. "Mommy, Donnie"s sick!"
Instantly Ca.s.sie was beside him. Donnie vomited once, twice, on an empty stomach. What came up was green slime mixed with mucus. Too much mucus, clogging his throat. Ca.s.sie cleared it as well as she could with her fingers, which made Donnie vomit again. His body felt on fire.
"T4S, what"s his temperature!"
"Stand away from him... one hundred three point four Fahrenheit."
Fear caught at her with jagged spikes. She stripped off Donnie"s pajamas and was startled to see that his torso was covered with a red rash rough to the touch.
Scarlet fever. It could follow from strep throat.
No, impossible. The incubation period for scarlet fever, she remembered from child-health programs, was eighteen days after the onset of strep throat symptoms. Donnie hadn"t been sick for eighteen days, or anything near it. What was going on?
"Mommy, is Donnie going to die? Like Daddy?"
"No, no, of course not, sweetie. See, he"s better already, he"s asleep again."
He was, a sudden heavy sleep so much like a coma that Ca.s.sie, panicked, woke him again. It wasn"t a coma. Donnie whimpered briefly, and she saw how painful it was for him to make sounds in his inflamed throat.
"Are you sure Donnie won"t die?" "Yes, yes. Go watch Pranopolis."
"It"s over," Janey said. "It was over a long time ago!"
"Then ask the smart program to run another cartoon for you!"
"Can I do that?" Janey asked interestedly. "What"s its name?"
"T4S.".
"It sounds like House."
"Well, it"s not House. Now let Mommy take care of Donnie."
She sponged him with cool water, trying to bring down the fever. It seemed to help, a little. As soon as he"d fallen again into that heavy, troubling sleep, Ca.s.sie raced for her equipment.
It had all finished running. She read the results too quickly, had to force herself to slow down so they would make sense to her.
The bacterium showed deviations in two sets of base pairs from the Streptococcus pyogenes genome in the databank as a baseline. That wasn"t significant in itself; S. pyogenes had many seriotypes. But those two sets of deviations were, presumably, modifying two different proteins in some unknown way.
The Faracci tester reported high concentrations of hyaluric acid and M proteins. Both were strong anti-phagocytes, interfering with Donnie"s immune system"s attempts to destroy the infection.
The protein a.n.a.lyzer showed the expected toxins and enzymes being made by the bacteria: Streptolysin O, Streptolysin S, erythrogenic toxin, streptokinase, streptodornase, proteinase. What was unusual was the startlingly high concentrations of the nastier toxins. And something else: a protein that the a.n.a.lyzer could not identify.
