Man-Kzin Wars IX by Larry Niven (best business books of all time .txt) 📕

I considered having the remaining five hauled in so I could ask a few questions. I didn't have to haul them in, my desk performs voice stress analysis perfectly well over the screen, but I prefer to talk to a suspect one on one. It makes the interview more personal, raising the stress level and giving the software something to work on. Besides, I like to see the reactions for myself and come to my own conclusions. The computer isn't infallible and neither am I. Using both techniques cuts the error rate.

If it worked I could wrap the case up that afternoon, if it didn't at least I could eliminate those five and get to work finding a new line of investigation. The risk was tipping off the murderer. If one of the suspects bolted, we'd have our man. Then we'd just have to find him. My instincts warned me that we never would. He'd disappear into the Swarm or the mountains down on Wunderland. Maybe in a year or ten the Provopolizei would catch him sniping politicians in Munchen for the Isolationists. The Isolationists would suit a schitz just fine.

My instincts were wrong, of course. I was used to Earth with its swarming crowds that could swallow a runner forever. Even on lightly settled Wunderland a fugitive who made it to the outskirts of Munchen could disappear into a thousand kilometres of virgin wilderness. In Tiamat's sealed environment there was nowhere to run and very few places to hide. Every time the suspect keyed a phone, the call would be monitored. Every time he thumbed a door or bought something, the computers would log it. Every time he walked a pedestrian mall, the vidscanners would be looking for him. If he were so foolish as to board a tube car, he'd be delivered right to the Goldskin headquarters' tube station and left locked in until I felt like coming to collect him. Tiamat was a law enforcement dream and a privacy nightmare. I punched the front desk and had my schitzies rounded up.

All five came in voluntarily, concerned about the murder, eager to do what they could to help. Ian Vanhoff was the one I had the most hope for. He ran a power loader in the container bays of the down-axis hub, giving him direct access to tunnel nineteen. I was sure I had the case locked up when I read that in his file. He gave me an ironclad alibi. The night Miranda disappeared he'd been working an extra shift in a storage bay on the other side of the asteroid. It hadn't been run through his personnel card yet because of union rules but his foreman and the rest of the loader crew could verify the times down to the minute. His wife could vouch for his arrival at home.

Thank you, citizen, you've been very helpful.

Dieter Lorz was at his girlfriend's apt that evening. She could corroborate that, as could another couple who'd visited with them.

Thank you, citizen.

Myro Havchek was upgrading his single-ship license. He'd been at the library studying. Yes, there were people who could testify they'd seen him there.

Get out of here, citizen. I've got a case to solve.

Two lacked alibis. Keve McCallum claimed to be asleep in his apt. Why hadn't the computer logged his entry? He didn't like the computer watching his every move, he had a mechanical lock on his door. Darren Sioban had been relaxing alone in a park on the 1G level. Why didn't he show as having taken the tube there? He'd walked, he needed the exercise.

Thank you, citizens.

The stress analyzer hadn't twitched, neither had my internal lie detector. I mulled it over. Could a schitz lie well enough to fool the computer and me? In our different ways we both responded to changes in stress. Getting past that would require nerves of ice.

So would taking Miranda apart.

Did not wanting the computer to know when you were home constitute paranoia? Knowing what I knew about information retrieval, it even made sense. What did Keve know about it? What did I expect from a registered schitz anyway? The drugs weren't perfect.

Were they?

Could a schitz off drugs construct a fantasy so powerful it became an internal reality? If the subject believed he was telling the truth, no lie detector would say anything else.

Was a schitz truly responsible for crimes committed while off drugs? I didn't even want to think about that one.

I had too many questions and not enough answers. I called up Johansen but she'd already gone. I dumped my interrogation files to her desk and tasked her to verify the alibis. I didn't expect them to be anything but solid. She wouldn't be thrilled with the job but she'd do it right.

I called up Dr. Morrow and found he'd gone home too. I hadn't realized how late it was getting. I asked the night intern a question. No, the drugs weren't perfect. Readjusting a schitz problem was a tightrope act. Too little and the patient destabilized. Too much and you had a walking zombie. Once upon a time any deviation from the social norm was drugged until it went away—totally. Now the doctors tried to intervene as little as possible. Around Alpha Centauri there wasn't even a law to enforce dosage. Minor personality quirks were not unusual.

I asked some more questions. Yes, a schitz off drugs might suppress a memory, or move in and out of an alternate reality. Yes, a schitz off drugs might have the cold control required to beat a lie detector.

What would happen when a criminal schitz had his drugs reinstated? Would his memory remain? How would he respond to the knowledge of his crimes? Anything was possible, it depended on the case.

Back to square zero.

Almost square zero. I left Johansen another message, asking her to collect blood samples from the group as well. Morrow could tell me if they were up to date
