Town Korolev. With dazzling impudence, they demanded that Yelen set them up with their own town on the north shore. That put them more than nine hundred kilometers from the rest of humanity-a distance more psychological than real, since it was a fifteen-minute flight on Yelen's new trans-sea shuttle. Nevertheless, it was a surprise that she yielded.
The surviving Korolev was... changed. Wil had talked to her only twice since the colony's return to realtime. The first time had been something of a shock. She looked almost the same as before, but there was a moment of nonrecognition in her eyes. 'Ah, Brierson,' she said mildly. Her only comment about Lu's providing him protection was to say that she would continue to do so also. Her hostility was muted; she'd had a long time to bury her grief.
Yelen had spent a hundred years following Marta's travels around the sea. She and her devices had stored and cataloged and studied everything that might bear on the murder. Marta's was already the most thoroughly investigated murder in the history of the human race.
Yelen had done another thing with the century she stayed behind: She had tried to reeducate herself. 'There's only one of us left, Inspector. I've tried to live double. I've learned everything I can about Marta's specialty. I've dreamed through Marta's memories of every project she managed.' A shadow of doubt crossed her face. 'I hope it's enough.' The Yelen he'd known before the murder would not have shown such weakness.
So, armed with Marta's knowledge and trying to imitate -Marta's attitudes, Yelen had relented and let the Peacers establish North Shore. She'd set up the trans-sea flier service. She'd encouraged a couple of the high-techs-Genet and Blumenthal-to move their principal estates there.
And the murder investigation had truly been left to Lu and Brierson.
Though he had talked to Korolev only twice, he saw Della Lu almost every day. She had produced a list of suspects. She agreed with Korolev: the crime was completely beyond the low-techs. Of the high-techs, Yelen and the Robinsons were still the best suspects. (Fortunately Lu was cagey enough not to report
At first, Wil thought the manner of the murder was a critical clue. He'd brought it up with Della early on. 'If the murderer could bypass Marta's protection, why not kill her outright? This business of marooning her is nicely poetic, but it left a real possibility that she might be rescued.'
Della shook her head. 'You don't understand.' Her face was framed with smooth black hair now. She'd stayed behind for nine months, the longest Yelen would allow. No breakthroughs resulted from the stay, but it had been long enough for her hair to grow out. She looked like a normal young woman now, and she could talk for minutes at a time without producing a jarring inanity, without getting that far, cold look. Lu was still the weirdest of the advanced travelers, but she was no longer in a class by herself. 'The Korolev protection system is good. It's fast. It's smart. Whoever killed Marta did it with software. The killer found a chink in the Korolev defensive logic and very cleverly exploited it. Extending the stasis period to one century was not by itself life-threatening. Leaving Marta outside of stasis was not by itself life-threatening.'
'Together they were deadly.'
'True. And the defense system would have normally noticed that. I'm simplifying. What the killer did was more complicated. My point is, if he had tried anything more direct, there is no amount of clever programming that could have fooled the system. There was no surefire way he could murder Marta. Doing it this way gave the killer the best chance of success.'
'Unless the killer is Yelen. I assume she could override all the system safeguards?'
'Yes.'
'Hmm. Marooning Marta left her defenseless. Why couldn't the murderer arrange an accident for her then? It doesn't make sense that she was allowed to live forty years.'
Della thought a moment. 'You're suggesting the killer could have bobbled everyone else for a century, and delayed bobbling himself?'
'Sure. A few minutes' delay would've been enough. Is that so hard?'
'By itself, it's trivial. But everyone was linked with the Korolev system for that jump. If anyone had delayed, it would show up in everyone's records. I'm an expert on autonomous systems, Wil. Yelen has shown me her system's design. It's a tight job, only a year older than mine. For anyone — except Yelen — to alter those jump records would be.. .'
'Impossible?' These systems people never changed. They could work miracles, but at the same time they claimed perfectly reasonable requests were impossible.
'No, maybe not impossible. If the killer had planned ahead, he might have an auton that didn't appear on his stasis roster. It could have been left outside of stasis without being noticed. But I don't see how the jump records themselves could be altered unless the killer had thoroughly infiltrated the Korolev system''
So they were dealing with a fairly impromptu act. And the queer circumstances of Marta's death were nothing more than a twenty- third-century version of a knife in the back.

Korolev had delivered Marta's diary soon after the colony returned to realtime. Wil's demand for it was one thing that could still bring a flare of anger to her face. In fact, Wil
