Terminal Experiment (23 page)

“Who does?” he said.

“Peter Hobson.”

“Oh, yes. We use some programs made by his company.”

“Nothing more?”

“Well, he’s a friend of mine, too. That’s why I have his home address in my Rolodex.” Sarkar looked innocent. “What were you expecting to find?”

Cathy Hobson was exhausted. It had been a long day at the office, slogging away at the Tourism Ontario account. She’d stopped at Miracle Food Mart on the way home, but the idiot in front of her had decided to unload all his change on the cashier. Some people, Cathy thought, should be forced to use debit cards.

When she finally arrived at home, she pressed her thumb against the FILE scanner, leaning on it as if it were the only thing keeping her from collapsing to the ground. The green LED atop the scanner winked at her, the dead bolt sprang back, and the heavy door slid aside. She entered her house. The door closed behind her and the lock snicked back into place.

“Lights,” she said.

Nothing happened. She cleared her throat and tried again. “Lights.”

Still nothing. She sighed, set down her shopping bags, and groped for the manual switch. She found it, but still the lights did not go on.

Cathy made her way up into the living room. She could see the glowing LEDs on the VCR, so it wasn’t a power failure; the entryway bulb was probably just burnt out. She said “lights” once more, but the three ceramic table lamps — lamps that Cathy herself had made — remained dark.

Cathy shook her head. Peter was constantly fiddling with the house controls, and it always took a while to get things working properly again.

She lowered herself to the couch, spreading her aching feet out in front of her. Such a long day. She closed her eyes, enjoying the darkness. After a moment, remembering her groceries, she hauled herself up and headed down to the entryway. She tried both the light switch and saying the word “lights” again. Still nothing. She was about to bend over and pick up the bags when she noticed the phone sitting on the little table in the hall. The large red light adjacent to its keypad was on. She moved closer. The visual display said “Line in use.” The phone hadn’t rung.

And Peter wouldn’t be home for hours yet; he had a board meeting tonight at North York General.

Unless … “Peter!” Her shout echoed slightly in the corridor. “Peter, are you home?”

No reply. She picked up the handset and heard a high-pitched whine. A modem.

She looked at the visual display again. “Private caller” — an incoming call, but whoever was using the modem had requested suppression of Call Display.

Jesus Christ
, she thought.
A sim
.

She slammed the handset down, then picked it up again, jiggling the hook switch rapidly, trying to make enough line noise to sever the connection.

It didn’t do any good. Peter, of course, had the finest in error-correcting modems, and the sim apparently had equally good hardware.

She moved quickly to the front door and pressed the UNLOCK button next to it. Nothing happened. She grabbed the manual handle. The door refused to budge. She hit the “In Case of Fire” override. The door was still jammed. She slid open the hall closet — it, at least, had no locking mechanism — and looked at the door control panel. An LED was glowing like a drop of blood next to the phrase “thwarting break-in.” Normally the doors would instantly unlock in case of a fire, but the smoke detectors denied that there was a fire, and some other detector said someone was trying to break in from outside. Cathy left the closet and looked through the peephole in the front door. No one was there. Of course.

She was trying to remain calm. There were other doors, but the master panel showed them all to be in anti-break-in mode as well. She could try going through a window, but they were all locked, too, and the glass was, of course, the best modern safety glass money could buy.

The word she’d been fighting not to think finally pushed to the surface of her consciousness.

Trapped.

Trapped in her own home.

She thought about trying to trigger the smoke detectors, but, of course, neither she nor Peter smoked, so there were no lighters anywhere in the house. And Peter didn’t like the smell of matches or candles, so there were none of those either. Still, she could set fire to some paper on the stove. That might set off the alarms, unlocking the doors.

She hurried to the kitchen, taking care not to trip in the darkness. The moment she entered, though, she knew she was in trouble. The digital clocks on both the microwave and the regular oven were off. The kitchen power had been cut. There was a rechargeable flashlight plugged into a wall outlet. She pulled it out of the socket. It was supposed to come on automatically when the power went off, but it was dead. Cathy realized that the power must have been off in the kitchen for many hours, and so the flashlight had depleted its charge. But — that whine. The refrigerator was still on. She opened its door and a light went on inside. She felt the rush of cold air on her face.

The sim knew exactly what it was doing: the VCR and the fridge were still on, but the stove and the outlet that recharged the flashlight were off. As was typical in a smart house, every outlet was on its own circuit and fuse.

She made her way into the dining room and held on to the back of a chair for support. She tried to remain calm — calm, dammit! She thought about getting a kitchen knife, but that was pointless — there was no physical intruder. The control box for the house systems was in the basement, and that’s where the phone cables entered, too — power and telecommunication lines were being systematically buried in response to fears that unshielded overhead lines caused cancer.

Cathy inched toward the top of the stairs that led to the basement. She opened the door. It was pitch black down there; for their fifth anniversary, Peter and Cathy had treated themselves to a home-theater system, so the blinds on the basement windows had been replaced with Mylar-lined curtains on electric rails — and the curtains had been drawn. Cathy thought she knew the layout well enough to find the incoming phone line even in the dark. She stepped onto the top stair—

The overhead sprinklers came on. No alarm — nothing to summon neighbors or the fire department. But cold water started showering down from the ceiling. Cathy gasped and ran back up into the living room. The sprinklers shut off behind her and came on in there. She moved onto the stairs leading up to the bedrooms. The sprinklers cut off in the living room and went on in the stairwell.

Cathy realized that they were following her — the sim had presumably keyed into the motion sensors that were part of the burglar-alarm system. Through the mist, she could see that the LEDs on the VCR were now off — presumably to avoid starting a fire by electrical shorting.

Exhausted and wet, with no way to escape, Cathy decided to head for the bathroom. If the sprinklers were destined to follow her, she might as well be in the room in which they could do the least damage. She got into the bathtub and unhooked the shower curtain, using it as a tent to shield herself from the cold water.

Three hours later, Peter came home. The front door unlocked normally for him. He found the living room carpet soaked, and could hear the sprinklers running upstairs. He hurried up to the bathroom and opened the door. The moment he did so, the sprinklers stopped.

Cathy pushed off the shower curtain. Water streamed from it as she rose to stand up in the tub. Her voice was full of tightly controlled fury. “Neither I nor any version of me would ever have done anything like this to you.” She glared at him. “We’re even.”

Cathy, quite sensibly, refused to stay in the house. Peter drove her to her sister’s apartment. She was still angry, but was slowly calming down, and she accepted his embrace as they parted. Peter then went directly to his own office and logged onto the net. He sent an E-mail message out into the world:

It didn’t take long for them to reply.

“I’m here,” said one of his ghosts.

“’Evening, Pete,” said another.

“What is it?” asked a third.

They all spoke through the same voice chip; unless they identified themselves, there was no easy way to tell which sim was speaking. And even knowing the nodes they were using wouldn’t tell him which sim was which. It didn’t matter.

“I know what’s going on,” said Peter. “I know one of you is killing people on my behalf. But tonight Cathy was threatened. I will not tolerate that. Cathy is not to be harmed. Not now, not ever. Understand?”

Silence.

“Understand?”

Still no reply.

Peter signed, exasperated. “Look, I know that Sarkar and I can’t remove you from the net, but if there’s any repetition, we will go public with your existence. The press would go apeshit over a story of a murdering AI having taken up residence inside the net. Don’t think they wouldn’t do a cold restart to get rid of you.”

A voice from the speaker: “I’m sure you’re mistaken, Peter. None of us would have committed murders. But if you go public, people will believe your claim — you are, after all, the famous Peter Hobson now. And that means you will be blamed for the deaths.”

“I don’t care at this point,” said Peter. “I’ll do whatever it takes to protect Cathy, even if it means going to jail myself.”

“But Cathy has hurt you,” said the synthesized voice. “More than anyone in the entire world, Cathy has hurt you.”

“Hurting me,” said Peter, “is not a capital crime. I’m not kidding: threaten her again, harm her in any way, and I will see to it that you are all destroyed. I’ll find a way to do that somehow.”

“We could,” said the electronic voice, very slowly, “get rid of you to prevent that from happening.”

“That would be suicide, in a sense,” said Peter. “Or fratricide. In any event, I know that’s something
I
wouldn’t do, and that means it’s also something that you wouldn’t do.”

“You would not have killed Cathy’s coworker,” said the voice, “and yet you believe one of us has done that.”

Peter leaned back in his chair. “No, but — but I
wanted
to. I’m ashamed to admit it, but I wanted to see him dead. But I would not kill myself — I wouldn’t even think about killing myself — and so I know you wouldn’t seriously think about doing it, either.”

“But you’re thinking about killing us,” said the voice.

“That’s different,” said Peter. “I’m the original. You know that. And I know in my heart of hearts that I don’t believe that computer simulacra are as alive as a flesh-and-blood person is. And because I believe that, you believe that, too.”

“Perhaps,” said the voice.

“And now you’re trying to kill Cathy,” Peter said. “At least that must stop. Don’t harm Cathy. Don’t threaten Cathy. Don’t do
anything
to Cathy.”

“But she hurt you,” said the synthesizer again.

“Yes,” said Peter, exasperated. “She hurt me. But it would hurt me
more
if she were not around. It would destroy me if she were dead.”

“Why?” said the voice.

“Because I love her, dammit. I love her more than life itself. I love her with every fiber of my being.”

“Really?” said the voice.

Peter paused, catching his breath. He considered. Was it just his anger talking? Was he blurting out things he didn’t mean? Or was it true — really true? “Yes,” he said softly, understanding at last, “yes, I really love her that much. I love her more than words can say.”

“It’s about time you admitted that, Petey-boy, even if you had to be pushed into it. Go get Cathy — doubtless you took her to her sister’s house; that’s what I would have done. Go get her and take her home. Nothing more will happen to her.”

The next day, Peter made sure Cathy got safely on her way to work, but he stayed home. He’d disconnected the electronic door system and had called a locksmith to come and put in old-fashioned key-operated dead bolts. While the locksmith worked, Peter sat in his office and stared out into space, trying to make sense of it all.

He thought about Rod Churchill.

A cold fish. Undemonstrative.

But he had been taking phenelzine — an antidepressant.

Meaning, of course, that he had been diagnosed as having clinical depression. But in the two decades Peter had known Rod Churchill, he’d seen no change in his demeanor. So maybe … maybe he’d been depressed for all that time. Maybe he’d been depressed even longer than that, depressed during Cathy’s childhood, leading him to be the lousy father he had been.

Peter shook his head. Rod Churchill — not a bastard, not an asshole. Just sick — a chemical imbalance.

Surely that mitigated what he’d done, made him less culpable for the way in which he’d treated his daughters.

Hell
, thought Peter,
we’re all chemical machines
. Peter couldn’t function without his morning coffee. There was no doubt that Cathy became more irritable just before her period. And Hans Larsen had let his hormones guide him through his life.

Which was the real Peter? The sluggish, irritable guy who pulled himself out of bed each morning? Or the focused, driven person who arrived at the office, the drug caffeine working its magic? Which was the real Cathy? The cheerful, bright, sexy woman she was most of the time, or the cranky, quarrelsome person she became for a few days each month? And which the real Larsen? The drunken, sex-crazed lout Peter had known, or the fellow who apparently had done his job well and been liked by most of his coworkers? What, he wondered idly, would the guy have been like if someone were to cut off his dick? Probably a completely different person.

What was left of a person if you removed stimulants and depressants, inhibitors and disinhibitors, testosterone and estrogen? And what about children who’d received too little oxygen during birth? What about Down’s syndrome — people altered completely by having an extra twenty-first chromosome? What about those with autism? Or dementia? Manic-depressives? Schizophrenics? Those who suffer from multiple personalities? Those with brain damage? Those with Alzheimer’s? Surely the individuals affected aren’t at fault. Surely none of those things reflect the actual people — the souls in question.

And what about those twin studies the Control sim had mentioned? Nature, not nurture, guided our behavior. When we weren’t dancing to a chemical tune, we were marching to the genetic drummer.

Yet Rod Churchill had been getting help.

If he’d really been killed in the way Detective Philo suggested, the sim would have known that Rod was taking phenelzine, would have looked it up in a database of drugs, would have understood what Rod was being treated for. Could the sim have failed to realize that although the treatment might be new, the condition could have been long-standing? Surely that would have been enough evidence to commute any death sentence the sim had been contemplating?

No — no version of him would have killed Rod Churchill, knowing of this chemical problem. Pity him, yes, but surely not kill him. In fact, this called into question all of Sandra Philo’s case. The sims, after all, had admitted to neither of the murders, and all Philo’s evidence pointing to Peter, and from there to the sims, was circumstantial.

Peter breathed a sigh of relief. He would not have killed Rod Churchill. Rod had simply done something stupid, failing to follow his doctor’s orders. And Hans Larsen? Well, Peter had always contended that dozens of angry spouses might have wanted him dead — including, now that he thought about it, Larsen’s own wife, who, Peter seemed to recall, worked in a bank and could have embezzled the funds needed to hire a hit man.

Fog, that’s all the case against him was. Empty fog.

And he’d prove that. He’d audit his own finances. Hiring a hit man would surely have cost tens of thousands of dollars, if not hundreds of thousands. Philo might never find the missing funds, even if she subpoenaed his financial records. But Peter had the advantage of thinking precisely the same way the sims did. If he looked — really looked — and could not find any missing money, well, then he could rest easy.

Peter dialed into his company’s mainframes, logged on to the corporate accounts database, and started digging. He used an accounting expert system made by Mirror Image to help him audit. As he moved through each account, each financial database, and found nothing amiss, his confidence grew. He was interrupted after an hour or so by the locksmith, who had finished his job. Peter thanked the man, paid him, and went back to his searching. Philo had been wrong, completely wrong. Just another cop who loved conspiracy theories. Why, he’d give her a piece of his mind—

His computer beeped.

Good Christ, thought Peter. Good Christ.

A discrepancy in the subrights licensing account. No memo, no payee’s account number, no cross-referenced invoice. Just a whopping big debit notice:

Peter stared at the screen, his jaw slack.

The timing was just about right. Hans had been killed three days later.

But surely it
had
to be something innocent. A refund for a licensing deal that had fallen through, maybe. Or an adjustment because of an overpayment to his company. Or…

No.

No, it could be none of those things. Peter’s comptroller was meticulous. No way she’d make an entry like that. And the notation EFT. Electronic funds transfer. Exactly what a sim would have to use.

He was about to log off when the console beeped at him again. Another hit in his database search:

Peter let out another sigh of relief. There — proof that this was all innocent. Surely no hit man would work on an installment plan. Whatever was causing these debits had to be something routine, then. Patent payments, perhaps. Or…

Two days ago. That second transaction had been just two days ago.

And then it came to him.

What Cathy had said.

“What will happen,” she’d asked, “to the detective when she gets too close to the truth? Will you want her dead, too?”

It couldn’t be, thought Peter. It could not be.

Killing Hans he could understand. Perhaps he didn’t approve, but at least he understood. Killing Rod Churchill was more difficult to fathom, given the extenuating circumstances. But maybe, just maybe, the electronic sim didn’t see biochemistry as an excuse.

But Sandra Philo hadn’t done anything evil, hadn’t hurt Peter in any way. She was just doing her job.

But now, apparently, she had become
inconvenient
.

Christ almighty, thought Peter. The guilty sim didn’t just have reduced morality or skewed morality. It had
no
morality at all.

Easy, Peter. Let’s not get ahead of the data…

But — no. It was there, even within the flesh-and-blood Peter — buried deep, but there: a desire for self-preservation. There was no one else he wanted dead — that was true. But the detective was putting him, and the sims, at risk. If he were to get rid of anyone now, it would be her. If any version of himself were to get rid of anyone now, it would be her.

Damn it. God damn it. He’d have no more blood on his hands. Peter immediately activated his telephone; a valid address was as good for dialing as was a name. “Metropolitan Toronto Police, 32 Division, on Ellerslie,” he said.

The Bell logo danced off the screen. A craggy sergeant appeared. “Thirty-two division,” he said.

“Sandra Philo,” said Peter.

“It’s her day off,” said the sergeant. “Can someone else help you?”

“No, it’s — it’s personal. Do you know where she is?”

“Haven’t a clue,” said the cop.

“I don’t suppose I could get her home number?”

The cop laughed. “You’ve got to be kidding.”

Peter broke the connection and dialed directory assistance. “Philo, Sandra,” he said, then spelled the last name.

“There is no such listing,” said the computerized voice.

Of course. “Philo, A.,” he said. “A for Alexandria.”

“There is no such listing.”

Dammit, thought Peter. But a cop would be crazy to have a listed phone number — unless it was still under her ex-husband’s name. “Do you have any listing for anyone with the last name Philo?”

“There is no such listing.”

Peter clicked off. There must be some way to get a hold of her…

City directories. He’d seen them at the public library. Originally, they’d been designed to find the name that went with an address, but with them now on random-access CD-ROMs, it was just as easy to do the reverse, finding an address that went with a name. Peter called the telephone reference line for the Central Branch of the North York Public Library.

“Hello,” said a woman’s voice. “Quick reference.”

“Hello,” said Peter. “Do you have city directories there?”

“Yes.”

“Could you tell me the address for Alexandria Philo, please? P-H-I-L-O.”

“Just a moment, sir.” There was a pause. “I have no A. Philo, sir. In fact, the only Philo is listed as Sandy.”

Sandy — a non-gender-specific version of her name. Exactly the sort of precaution an intelligent woman living alone would take. “What does Sandy Philo do for a living?”

“It says ‘civil servant,’ sir. I suppose that could mean just about anything. ”

“that’s her. What’s the address, please?”

“Two-sixteen Melville Avenue.”

Peter jotted that down. “Is there a phone number?”

“It’s marked unlisted.”

“Thank you,” said Peter. “Thank you very much.”

He clicked off. Peter had never heard of Melville Avenue. He called up his electronic map book and looked it up. It was here in Don Mills. Not that far. Maybe a twenty-minute drive. It was crazy, he knew — a paranoid fantasy. And yet…

He hurried to his car and put the pedal to the metal.
