She heard his approach and turned. She wore a phosphorescent white domino, with metallic blue sequins. It was hard to see her eyes.

"Hello, Frank," she said, as if he wore no mask. He almost turned and ran. Mere recognition was almost enough to do it . . . .

But he stayed. He said, "Hello, Maya. Nice sunset, wasn't it?"

"Spectacular. Nature has no taste. It's just a city inauguration, but it looked like Judgement Day."

They were under a streetlight, standing on their shadows. She said, "Have you enjoyed yourself?"

"Very much. And you?"

"It's getting a little wild."

"It's understandable, don't you think? We're out of our holes, Maya, we're on the surface at last! And what a surface! You only get these kind of long views on Tharsis."

"It's a good location," she agreed.

"It will be a great city," Frank predicted. "But where do you live these days, Maya?"

"In Underhill, Frank, just as always. You know that."

"But you're never there, are you? I haven't seen you in a year or more."

"Has it been that long? Well, I've been in Hellas. Surely you heard?"

"Who would tell me?"

She shook her head and blue sequins glittered. "Frank." She turned aside, as if to walk away from the question's implications.

Angrily Frank circled her, stood in her path. "That time on the Ares," he said. His voice was tight, and he twisted his neck to loosen his throat, to make speech easier. "What happened, Maya? What happened?"

She shrugged and did not meet his gaze. For a long time she did not speak. Then she looked at him. "The spur of the moment," she said.

And then it was ringing midnight, and they were in the martian time slip, the thirty-nine and a half minute gap between 12:00:00 and 12:00:01, when all the clocks went blank or stopped moving. This was how the first hundred had decided to reconcile Mars's slightly longer day with the twenty-four hour clock, and the solution had proved oddly satisfactory. Every night to step for a while out of the flicking numbers, out of the remorseless sweep of the second hand...

And tonight as the bells rang midnight, the whole city went mad. Forty minutes outside of time; it was bound to be the peak of the celebration, everyone knew that instinctively. Fireworks were going off, people were cheering; sirens tore through the sound, and the cheering redoubled. Frank and Maya watched the fireworks, listened to the noise.

Then there was a noise that was somehow different: desperate cries, serious screams. "What's that?" Maya said.

"A fight," Frank replied, cocking an ear. "Something done on the spur of the moment, perhaps." She stared at him, and quickly he added, "Maybe we should go have a look."

The cries intensified. Trouble somewhere. They started down through the park, their steps getting longer, until they were in the martian lope. The park seemed bigger to Frank, and for a moment he was scared.
