Sando wanted to send her away for medical supervision, but Joan insisted on remaining at the site.
"The fewer officials who get to know about this incident, the fewer problems it makes for you," she reasoned.
"As long as you don't get sick and die," he replied.
"I'm not going to die." Her wounds had not become infected, and her strength was returning rapidly.
They compromised. Sando hired someone to drive up from the nearest town to look after her while he was out at the excavation. Daya had basic medical training and didn't ask awkward questions; he seemed happy to tend to Joan's needs, and then lie outside daydreaming the rest of the time.
There was still a chance, Joan thought, that the Niah had carved the theorem on a multitude of tablets and scattered them all over the planet. There was also a chance that the Tirans had made copies of the tablet before letting Anne abscond with it. The question, though, was whether she had the slightest prospect of getting her hands on these duplicates.
Anne might have made some kind of copy herself, but she hadn't mentioned it in the prologue to her aerobatic rendition of the theorem. If she'd had any time to spare, she wouldn't have limited herself to an audience of one: she would have waited until the node had risen over Ghahar.
On her second night as an invalid, Joan dreamed that she saw Anne standing on the hill looking back into the fog-shrouded valley, her shadow haloed by the Niah light.
When she woke, she knew what she had to do.
When Sando left, she asked Daya to bring her the console that controlled the satellite dish. She had enough strength in her arms now to operate it, and Daya showed no interest in what she did. That was naive, of course: whether or not Daya was spying on her, Pirit would know exactly where the signal was sent. So be it. Seven light years was still far beyond the Noudah's reach; the whole node could be disassembled and erased long before they came close.
No message could outrace light directly, but there were more ways for light to reach the node than the direct path, the fastest one. Every black hole had its glory, twisting light around it in a tight, close orbit and flinging it back out again. Seventy-four hours after the original image was lost to them, the telescopes at the node could still turn to the Cataract and scour the distorted, compressed image of the sky at the rim of the hole's black disk to catch a replay of Anne's ballet.
Joan composed the message and entered the coordinates of the node. You didn't die for nothing, my friend. When you wake and see this, you'll be proud of us both.
She hesitated, her hand hovering above the send key. The Tirans had wanted Anne to flee, to show them the way to the stars, but had they really been indifferent to the loot they'd let her carry? The theorem had come at the end of the Niah's three-million-year reign. To witness this beautiful truth would not destroy the Amalgam, but might it not weaken it? If the Seekers' thirst for knowledge was slaked, their sense of purpose corroded, might not the most crucial strand of the culture fall into a twilight of its own? There was no shortcut to the stars, but the Noudah had been goaded by their alien visitors, and the technology would come to them soon enough.
The Amalgam had been goaded, too: the theorem she'd already transmitted would send a wave of excitement around the galaxy, strengthening the Seekers, encouraging them to complete the unification by their own efforts. The Big Crunch might be inevitable, but at least she could delay it, and hope that the robustness and diversity of the Amalgam would carry them through it, and beyond.
She erased the message and wrote a new one, addressed to her backup via the decoy node. It would have been nice to upload all her memories, but the Noudah were ruthless, and she wasn't prepared to stay any longer and risk being used by them. This sketch, this postcard, would have to be enough.
When the transmission was complete she left a note for Sando in the console's memory.
Daya called out to her, "Jown? Do you need anything?"
She said, "No. I'm going to sleep for a while."
