Sitting was uncomfortable with the bruised hip, but I managed to ease into the console and spend an hour or so studying logic and wiring diagrams. Then I popped off an access plate and moved the micro-waldo down the corridors of electronic thought. The intercom began buzzing incessantly, but I didn’t let it interfere with my concentration.

Nearside is protected from meteorite strike or (far more likely) structural failure by a series of 128 bulkheads that, like the emergency wall here, can slide into place and isolate any area where there’s a pressure drop. It’s done automatically, of course, but can also be controlled from here.

What I did, in essence, was to tell each bulkhead that it was under repair, and should not close under any circumstance. Then I moved the waldo over to the circuits that controlled the city’s eight airlocks. With some rather elegant microsurgery, I transferred control of all eight solely to the pressure switch I now hold in my left hand.

It is a negative-pressure button, a dead-man switch taken from a power saw. So long as I hold it down, the inner doors of the airlock will remain locked. If I let go, they will all iris open. The outer doors are already open, as are the ones that connect the airlock chambers to the suiting-up rooms. No one will be able to make it to a spacesuit in time. Within thirty seconds, every corridor will be full of vacuum. People behind airtight doors may choose between slow asphyxiation and explosive decompression.

My initial plan had been to wire the dead-man switch to my pulse, which would free my good hand and allow me to sleep. That will have to wait. The wiring completed, I turned on the intercom and announced that I would speak to the Coordinator, and no one else.

When I finally got to talk to him, I told him what I had done and invited him to verify it. That didn’t take long. Then I presented my demands:

Surgery to replace the rest of my limbs, of course. The surgery would have to be done while I was conscious (a heartbeat dead-man switch could be subverted by a heart machine) and it would have to be done here, so that I could be assured that nobody fooled with my circuit changes.

The doctors were called in, and they objected that such profound surgery couldn’t be done under local anesthetic. I knew they were lying, of course; amputation was a fairly routine procedure even before anesthetics were invented. Yes, but I would faint, they said. I told them that I would not, and at any rate I was willing to take the chance, and no one else had any choice in the matter.

(I have not yet mentioned that the ultimate totality of my plan involves replacing all my internal organs as well as all of the limbs—or at least those organs whose failure could cause untimely death. I will be a true cyborg then, a human brain in an “artificial” body, with the prospect of thousands of years of life. With a few decades—or centuries!—of research, I could even do something about the brain’s shortcomings. I would wind up interfaced to EarthNet, with all of human knowledge at my disposal, and with my faculties for logic and memory no longer fettered by the slow pace of electrochemical synapse.)

A psychiatrist, talking from Earth, tried to convince me of the error of my ways. He said that the dreadful trauma had “obviously” unhinged me, and the cyborg augmentation, far from affecting a cure, had made my mental derangement worse. He demonstrated, at least to his own satisfaction, that my behavior followed some classical pattern of madness. All this had been taken into consideration, he said, and if I were to give myself up, I would be forgiven my crimes and manumitted into the loving arms of the psychiatric establishment.

I did take time to explain the fundamental errors in his way of thinking. He felt that I had quite literally lost my identity by losing my face and genitalia, and that I was at bottom a “good” person whose essential humanity had been perverted by physical and existential estrangement. Totally wrong. By his terms, what I actually am is an “evil” person whose true nature was revealed to himself by the lucky accident that released him from existential propinquity with the common herd.

And “evil” is the accurate word, not maladjusted or amoral or even criminal. I am as evil by human standards as a human is evil by the standards of an animal raised for food, and the analogy is accurate. I will sacrifice humans not only for any survival but for comfort, curiosity, or entertainment. I will allow to live anyone who doesn’t bother me, and reward generously those who help.

Now they have only forty minutes. They know I am

Excerpt from Summary Report

I am Dr. Henry Janovski, head of the surgical team that worked on the ill-fated cyborg augmentation of Dr. Wilson Cheetham.

We were fortunate that Dr. Cheetham’s insanity did interfere with his normally painstaking, precise nature. If he had spent more time in preparation, I have no doubt that he would have put us in a very difficult fix.

He should have realized that the protecting wall that shut him off from the rest of Nearside was made of steel, an excellent conductor of electricity. If he had insulated himself behind a good dielectric, he could have escaped his fate.

Cheetham’s waldo was a marvelous instrument, but basically it was only a pseudo-intelligent servomechanism that obeyed well-defined radio-frequency commands. All we had to do was override the signals that were coming from his own nervous system.

We hooked a powerful amplifier up to the steel wall, making it in effect a huge radio transmitter. To generate the signal we wanted amplified, I had a technician put on a waldo sleeve that was holding a box similar to Cheetham’s dead-man switch. We wired the hand closed, turned up the power, and had the technician strike himself on the chin as hard as he could.

The technician struck himself so hard he blacked out for a few seconds. Cheetham’s resonant action, perhaps a hundred times more powerful, drove the bones of his chin up through the top of his skull.

Fortunately, the expensive arm itself was not damaged. It is not evil or insane by itself, of course. Which I shall prove.

The experiments will continue, though of course we will be more selective as to subjects. It seems obvious in retrospect that we should not use as subjects people who have gone through the kind of trauma that Cheetham suffered. We must use willing volunteers. Such as myself.

I am not young, and weakness and an occasional tremor in my hands limit the amount of surgery I can do—much less than my knowledge would allow, or my nature desire. My failing left arm I shall have replaced with Cheetham’s mechanical marvel, and I will go through training similar to his—but for the good of humanity, not for ill.

What miracles I will perform with a knife!

FLOWER, MERCY, NEEDLE, CHAIN

The usual fallacy is that, in every universe, many futures splay outward from any given moment. But in some universes, determinism runs backwards: given a universe’s state s at some time t, there are multiple previous states that may have resulted in s. In some universes, all possible pasts funnel toward a single fixed ending, Ω.

If you are of millenarian bent, you might call Ω Armageddon. If you are of grammatical bent, you might call it punctuation on a cosmological scale.

If you are a philosopher in such a universe, you might call Ω inevitable.

She is human, and her straight black hair and brown-black eyes suggest an ancestral inheritance tangled up with tigers and shapeshifting foxes. Her native language is not spoken by anyone here or elsewhere.
