第14章 The Surveyor's Hand
They camped in a shepherd hut above the river, four walls of dry stone and a roof of poles and brush, and Kulin sat with his back to the door and talked for three hours while Tufan watched the road and Zeyla wrote everything down.
He had come to the consortium the way academics come to money, by believing he could keep his hands clean and direct the work toward a museum. He had lasted six months. Zeydan's method was not to loot and run. It was to buy, quietly, the objects that came out of the ground for a generation, and to sell them slowly, to collectors who would not ask, and to hold the provenance in his own files so that in fifty years the collection would seem always to have existed. Kulin had understood this in the spring, and had begun, out of a mixture of shame and strategy, to salt the consortium's supply with forgeries.
"A forgery does two things," he said. "It wastes their time, and it tells the person who reads it that someone else is on the road. I assumed the reader would be an academic with an archive. I did not expect the reader to be the granddaughter."
"Who cut the forgeries?"
"I did. I copied them from the only real text I had access to, which was a photograph of the sixth stone that Zeydan bought from a dealer in the north." He held up a hand. "And before you ask, I do not know where the real sixth stone is now. Zeydan moved it. But I know what it says, and I know what it means, and that is why I am here."
"What does it mean?"
Kulin looked at the fire and then at Zeyla, and there was something in his face that she had never seen there in fifteen years of conferences and committees: humility, and a little fear.
"It means I have been reading the distances wrong. All of us have. Zeydan's surveyors measured the stones with tape and converted the numbers into kilometers, and the kilometers pointed into the middle of the salt flats and stopped. That is why they built the decoy theory. They could not make the numbers work, so they assumed the road had two false endings." He leaned forward. "The numbers are not kilometers. I checked the fifth stone's number against the bridge, and the bridge is not eleven kilometers from the Tavras stone. It is eleven hours of shadow."
Zeyla set down her pencil.
"Say that again."
"Eleven hours of shadow. The old measurement. The length of a shadow cast by a man of a certain height, measured hour by hour through the day, in a country where the summer sun is the only clock anyone can afford." He spread his hands. "Sarpel measured the road in shadows, not distance, and shadows change with the season, and the season is written into the first character of each stone. That is why the numbers never matched. They were never meant to match a straight line. They were meant to match a day."
Zeyla sat very still. She thought about the first rubbing, the one from the milestone at Sarnem, and the phrase she had taken for a maker's mark, and the way Mehve's notebook had abbreviated the entries with the same three letters over and over. Then she opened the notebook and laid the rubbings out beside it, all five of them, and began, for the first time, to read them together.
It took her until dawn.
The stones were not points on a map. They were observations, each one taken from a different place on a known day, each one recording the direction and length of the shadow at a stated hour. Nine observations of one shadow, made from nine stations along the road. And a surveyor who has nine observations of the same object can do the thing that had made Zeyla famous before the committee destroyed her. He can solve for the object's position without ever visiting it. He can find the place the shadow was cast from.
"The tenth stone is not part of the sequence," she said, when the light came up. "It is the object. It is the thing the nine are observing."
"Where is it?"
"That is the whole trick." She turned the notebook toward him and put her pencil on the curve of nine dots, on the torn place at the southern end. "It is not on the road at all. It is where the road was pointed. And every stone gives a bearing, and no two bearings point to the same place, because the stones were set out to hide the answer. Unless you hold all nine, at the correct hours, and correct for the seasons, and then the nine bearings converge on one spot."
She drew a small circle in the margin, at the point where the lines crossed, and the circle sat on a place that she had seen on no map and that she nonetheless recognized, because she had been standing near it, without knowing it, for a week.
"Zerabet," she said. "The ruined fortress on the salt edge. Mehve wrote the answer in her notebook and then crossed it out, because she knew that anyone who found the notebook could do exactly what I have just done." She looked up. "She was not warning me about the ninth stone. She was warning anyone about the ninth stone, so that a careless reader would fix on the wrong number and spend a lifetime in the flats. She was protecting the road."
Kulin was silent for a long moment. "There is one more thing," he said. "The copy. The one Sarpel made for the person he trusted. I have never seen it, but Zeydan believes it exists, and he believes it is buried with the cache at Zerabet. If it is there, it is worth more than the silver, because it is the only complete description of how the road was built. Whoever holds it holds the method. Whoever holds the method can find anything Sarpel ever hid."
"Then we have a day," Zeyla said, "and a mule, and no camera, and a notebook, and about four hundred words of reading between us and the end of the road."
"And a guide who has lied to the other side," Kulin said, looking at Tufan in the doorway.
"He is standing right there," Tufan said. "And he hears you."
