“No one is,” Art said. They stared at him, and he went on: “I heard about it in my orientation in Sheffield. It’s a Praxis project. They rebuilt it, and got everything ready. And now they’re just waiting.”

“Waiting for what?”

“For Sax Russell, basically. For Taneev, Kohl, Tokareva, Russell . . .” He looked at Sax, shrugging almost apologetically.

Sax croaked something wordlike.

“Hey!” Coyote said.

Sax cleared his throat hard, tried again. His mouth pursed to a little O, and a horrible noise started deep in his throat: “W-w-w-w-w-” He looked over at Nirgal, gestured as if Nirgal would know.

“Why?” Nirgal said.

Sax nodded.

Nirgal felt his cheeks burn as an electric flush of acute relief ran through his skin, and he leaped up and gave the little man a hard hug. “You do understand!”

“Well,” Art was saying, “they did it as a kind of gesture. It was Fort’s idea, the guy who founded Praxis. ‘Maybe they’ll come back,’ he supposedly said to the Praxis people in Sheffield. I don’t know if he thought out the practicalities or not.”

“This Fort is strange,” Coyote said, and Sax nodded again.

“True,” Art said. “But I wish you could meet him. He reminds me of the stories you tell about Hiroko.”

“Does he know we’re out here?” Spencer asked.

Nirgal’s pulse leapt, but Art showed no sign of discomfort. “I don’t know. He suspects. He wants you to be out here.”

“Where does he live?” Nirgal asked.

“I don’t know.” Art described his visit to Fort. “So I don’t know exactly where he is. Somewhere on the Pacific. But if I could get word to him . . .”

No one responded.

“Well, maybe later,” Art said.

Sax was looking out the rover’s low windshield at the distant rock fin, at the tiny line of lit windows marking the labs behind them, empty and silent. Coyote reached out and squeezed his neck. “You want it back, don’t you.”

Sax croaked something.

On the empty plain of Amazonis there were few settlements of any kind. This was the back country, and they rolled rapidly south through it, night after night, and slept in the darkened cabin of the car through the days. Their biggest problem was finding adequate hiding places. On flat open plains the boulder car stood out like a glacial erratic, and Amazonis was almost nothing but flat open plain. They usually tucked into the apron of ejecta around one of the few craters they passed. After the dawn meals Sax sometimes exercised his voice, croaking incomprehensible words, trying to communicate with them and failing. This upset Nirgal even more than it seemed to bother Sax himself, who, though clearly frustrated, did not seem pained. But then he had not tried to talk to Simon in those last weeks. . . .
