“Nadia is the princess of Mars,” Jackie said, and went to the kitchen nook. Maya scowled at her back, and noticed Art watching her curiously. He did not flinch when she stared at him, and she went to her room to change clothes. Michel was in there cleaning up, making room for people to sleep on the floor. It was going to be an irritating evening.

The next morning when she got up early to go to the bathroom, feeling hung over, Art was already up. Over the sleeping bodies on the floor he whispered, “Want to go out and get breakfast?”

Maya nodded. When she was dressed they walked down the stairs and out, through the park and along the corniche, which was lurid in the horizontal beams of dawn sunlight.

They stopped in a café that had just washed down its section of sidewalk. On the dawn-stained white wall of the

building, a sentence had been painted with the help of a stencil, so that it was neat and small, and brilliantly red:

YOU CAN NEVER GO BACK

“My God,” Maya exclaimed.

“What?”

She pointed at the graffito.

“Oh, yeah,” Art said. “You see that painted all over Sheffield and Burroughs these days. Pithy, eh?”

“Ka wow.”

They sat in the chill air by a small round table, and ate pastries and drank Turkish coffee. The ice on the horizon blinked like diamonds, revealing some movement under the ice. “What a fantastic sight,” Art said.

Maya looked at the bulky Terran closely, pleased at his response. He was an optimist like Michel, but more canny about it, more natural; with Michel it was policy, with Art, temperament. She had always considered him to be a spy, from the first moment they had rescued him from his too-convenient breakdown out in their path: a spy for William Fort, for Praxis, perhaps for the Transitional Authority, perhaps for others as well. But now he had been among them for so long— a close friend of Nirgal, of Jackie, of Nadia as well . . . and they were in fact working with Praxis now, depending on it for supplies, and protection, and information about Earth. So she was no longer so sure— not only whether Art was a spy, but what, in this case, a spy was.

“You’ve got to stop them from making this assault on Kasei Vallis,” she said.

“I don’t think they’re waiting on my permission.”

“You know what I mean. You can talk them out of it.”

Art looked surprised. “If I could talk people out of things that well, we’d be free already.”

“You know what I mean.”

“Well,” Art said. “I suppose they’re afraid they won’t be able to break the code again. But Coyote seems pretty confident he has the protocol. And it was Sax helped him work it out.”

“Tell them that.”

“For what it’s worth. They listen to you more than me.”

“Right.”
