How so?

The day your body died, she asked me what I was going to do with the stockpile of precious metal. I hadn't released the information then. Which meant the two of you had known about it all along. The only way that could happen was if your affinity command of Eden's personality was superior to everyone else's. A logical assumption since you designed its thought routines to begin with.

And that told you I was the murderer?

Not at once, but it set me to thinking. How could Wallace Steinbauer, who has only been in Eden for two years, have developed a method of glitching the thought routines which surpassed even your ability? Especially given that his field of expertise was cybernetics. So then I started to consider what he had done a little more closely. The most obvious question was why didn't he simply blackmail Penny Maowkavitz when it became obvious she had discovered he was stealing the gold? She could hardly come running to me. So it would have resulted in a complete stand-off between them, because if he had gone to the JSKP board about her initial subterfuge they would then find out that he had been stealing the gold as well. At worst she would have to agree to let him continue substituting the Dornier's standard components with the new gold ones. Even if he had remade the entire capsule out of gold it wouldn't amount to a hundredth of a per cent of the total value of the stockpile. That would have been a very small price to pay for safeguarding the future of Boston. So I had to start looking for ulterior motives, and someone else who could manipulate the habitat's personality. The only people who qualified on the second count were you and Hoi Yin. That left me with motive. Hoi Yin had the obvious one, she hated Penny Maowkavitz, and with good reason. But she also admitted she felt cheated that Maowkavitz hadn't died from cancer. It was fairly macabre, but I believed her. That left you.

And do you have my motive, Harvey?

I think so. That was the hardest part of all to figure out. After all, everybody up here knew Maowkavitz was dying, that she would be dead in a few months at the most. So the actual question must be, why would you want her to die now ? What was so special about the timing? Then I realized two things. One, you were also dying, but you were expected to live longer than her. And second, Penny Maowkavitz's death was fast, deliberately so. With your control over Eden you could have chosen from a dozen methods; yet you picked a bullet through the brain, which is damn near instantaneous. In other words, you made sure Penny Maowkavitz never had an opportunity to transfer her personality into the neural strata. You killed her twice, Chong, you shot her body and denied her mind immortality.

With reason, Harvey. I could not allow her to transfer herself into the neural strata before me, it would have been disastrous. And Maowkavitz had begun to think along those lines, she was not stupid. She was conferring with Eden to see if such a thing were possible. Which of course it is, it has been right from the start. As she did not reveal the existence of the precious metals, so I did not reveal the full potential of the neural strata. I had to ensure that Maowkavitz did not have the chance to experiment; and as I was already aware of Steinbauer's illegal activity, I decided to use him as my alibi. Fortunately, given his temperament his elimination was even easier to engineer than Maowkavitz's. I had only to wait until your department uncovered his theft of the gold, then goad him into panic at the prospect of discovery. The inspection tunnel was only one of a number of options I had prepared for him depending on how he reacted. Once he was dead, he could not protest his innocence, and the case would be closed.
