Coyote laughed. “Oh yes! Between those journeys and the solar storm on the Ares, I took on more rems than anyone in the First Hundred, except maybe for John. Maybe that’s what did it. Anyway”— he shrugged, looked up at Art and Nirgal—”here I am. The stowaway.”

“Amazing,” Art said.

Nirgal nodded; he had never gotten his father to reveal even a tenth as much information about his past, and now he looked from Art to Coyote and back again, wondering how Art had done it. And done it to him as well— for Nirgal had tried to tell not only what had happened to him, but what it had meant, which was much more difficult. Apparently this was a talent Art had, though it was very hard to pin down what it consisted of; just the look on his face, somehow, that cross-eyed intensity of interest, those bald bold questions, trampling on the niceties and going right to the heart of things— assuming that every person wanted to talk, to shape the meaning of their life. Even secretive weird old hermits like Coyote.

“Well, it was not that hard,” Coyote was saying now. “Concealment is never as hard as people think, you must understand that. It’s action while hiding that is the hard part.”

At that thought he frowned, then pointed a finger at Nirgal. “This is why we will have to come out eventually, and fight in the open. This is why I got you to go to Sabishii.”

“What? You told me I shouldn’t go! You said it would ruin me!”

“That was how I got you to go.”

They kept up this nocturnal, conversational life for the better part of a week, and at the end of it they approached a small settled region surrounding the mohole that had been dug in the midst of craters Hipparchus, Eudoxus, Ptolemaeus, and Li Fan. There were some uranium mines on the aprons of these craters, but Coyote did not suggest any sabotage attempts, and they drove hard past the Ptolemaic mohole, getting away from the region as quickly as possible. Soon they came to the Thaumasia Fossae, the fifth or sixth big fracture system they had encountered on their trip. Art found this curious, but Spencer explained to him that the Tharsis bulge was surrounded by fracture systems caused by its uplift, and as they were in effect circumnavigating the bulge, they kept running into them. Thaumasia was one of the biggest of these systems, and the location of the large town of Senzeni Na, which had been founded next to another of the 40° latitude moholes, one of the first moholes to be dug, and still one of the deepest. At this point they had been traveling for over two weeks, and they needed to restock at one of Coyote’s caches.
