away from the place with the pistachio nuts, back towards the open daylight.

      Emma follows him. But he has forgotten Emma. He remembers the nuts and the fungus and the Nutcracker-man.

      Reid Malenfant:

      He kept right on pulling on his pants. When he was done, his breath misting slightly, he walked up the slope of the eroded beach.

      His silent observer was a woman: little more than a girl, really, slim, composed, dark. She was wearing a nondescript jumpsuit. She was very obviously Japanese.

      ‘I know you,’ he said.

      ‘We have not met.’ Her voice was deep, composed. ‘But, yes, I know you too, Reid Malenfant.’

      ‘Just Malenfant,’ he said absently, trying to place her. Then he snapped his fingers. ‘You were on Station when –’

      ‘– when the Moon changed. Yes. My name is Nemoto.’ She bowed. ‘I am pleased to meet you.’

      He bowed back. He felt awkward. He couldn’t care less if she had glimpsed his wrinkly ass. But he wished, oddly, that he had his shoes on.

      He looked up and down the beach. He saw no sign of transportation, not so much as a bicycle. ‘How did you get here?’

      ‘I walked. I have a car, parked at the Beachhouse.’

      ‘As I have.’

      ‘Yes.’

      ‘Will you walk back that way with me?’

      ‘Yes.’

      Side by side, in the gathering pink-grey light, they walked north along the beach.

      Malenfant glanced sideways at Nemoto. Her face was broad, pale, her eyes black; her hair was elaborately shaved, showing the shape of her skull. She could have been no more than half Malenfant’s age, perhaps twenty-five.

      ‘The Red Moon is very bright,’ she said.

      ‘Yes.’

      ‘It is a great spectacle. But it will be bad for the astronomers.’

      ‘You were an astronomer …’

      ‘I am an astronomer.’

      ‘Yeah. Sorry.’

      Nemoto was a Japanese citizen trained as an astronaut at NASA. Her speciality had been space-based astronomy. She had been the brilliant kid who had made it all the way into space at the incredibly young age of twenty-four. He remembered Nemoto as being bright, excitable, even bubbly. Well, she wasn’t bright and bubbly now. It was as if she had gone into eclipse.

      ‘I have been looking for you,’ she said now. ‘I have missed you several times in your tour of the NASA centres. Malenfant, when you are not at your scheduled meetings, you are something of a recluse.’

      ‘Yeah,’ he said ruefully. ‘Nowadays more than I’d like to be.’

      ‘You miss your wife,’ she said bluntly.

      ‘Yes. Yes, I miss my wife.’

      ‘I almost found you at your church.’

      ‘The chapel at Ellington Air Force Base?’

      ‘I had not realized you are Catholic’

      ‘I guess you should call me lapsed. I converted when I married Emma, back in ’82. Emma, my wife. It was for the sake of her family. When I joined NASA we looked around for a chapel. Ellington was near Johnson, and a lot of my colleagues and their families went there, and we liked the priest …’

      ‘Are you religious now?’

      ‘No.’ He had tried, for the sake of the priest, Monica Chaum, as much as anybody else. But, unlike some who came back from space charged with religious zeal, Malenfant had lost it all when he made his first flight into orbit. Space was just too immense. Humans were like ants on a log, adrift in some vast river. How could any Earth-based ritual come close to the truth of the God who had made such a universe?

      ‘So I gave up the chapel. It caused some problems with Emma’s family. But she supported me. She always did.’

      ‘But now you have returned to the faith?’

      ‘No. I do find the chapel kind of restful. But I get a lot more comfort from going out on a toot with Monica Chaum over at the Outpost. She has quite a capacity for a woman Catholic priest. I make no excuses; I’d been through a lot.’ He eyed her. ‘As have you.’

      ‘Yes.’ Her face, never beautiful, was empty of expression. ‘As is well known.’

      Nemoto had been aboard the International Space Station, in low Earth orbit, when the Red Moon had made its dramatic entrance. Nemoto had been forced to watch from orbit as the first great tides battered at Japan.

      ‘I returned to Earth as soon as I could. I and my colleague used our Japanese Hope shuttle. You may know that our landing facility was at Karitimati Island in the South Pacific –’

      ‘Where? Oh, yeah, Christmas Island.’

      ‘There is little left of Karitimati. We were forced to come down here, at KSC.’

      He said carefully, ‘Where was your home?’

      ‘I have no home now,’ was all she would reply.

      He nodded. ‘Nor do I.’ It was true. He had an empty house in Clear Lake, but the hell with that. His home was with Emma – wherever she was.

      Nemoto paused and looked into the sky. Although the first liquid glimmer of sun was resting on the horizon, the Red Moon still shone bright in the sky. ‘If you have abandoned your attempts to acquire faith, you do not believe that God is responsible for that?’

      He grinned, rubbing his hand over his bare scalp, feeling a time of salt there. ‘Not God, no. But I think somebody is.’

      ‘And you would like to find out who.’

      ‘Wouldn’t you?’

      ‘Do you believe that the bodies which fell through the African portal were human?’

      He frowned, taken aback by the question. ‘Nobody can make much of the mashed-up remains that they scraped out of the savannah.’

      ‘But they appear to be human, or a human variant. You saw them, Malenfant. I’ve read your testimony. They share our DNA – much of it, though the recovered sequences show a large diversity from our own genome. There is speculation that they are more like one of our ancestors, a primitive hominid species.’

      ‘Yeah. So there are ape-men running all over our new Moon up there, right? I read the tabloids too.’

      ‘Malenfant, what do you believe?’

      He said fiercely, ‘I believe that the Wheel was some kind of portal. I believe it linked Earth to its new Moon. And I believe it transported those poor unevolved saps, here from there. What I don’t know is what the hell it all means.’

      ‘And you believe your wife made the return journey. That she is still alive up there on the Red Moon, breathing its air, drinking its water, perhaps eating its vegetation.’

      ‘Where else could she be?… I’m sorry. It’s what I want to believe, I guess. It’s what I have to believe.’

      ‘Yes.’ She smiled. ‘Everybody knows this, Malenfant. Your longing to reach her is tangible. I can see it, now, in your eyes, the set of your body.’

      ‘You think I’m an asshole,’ he said brutally. ‘You think I should let go.’

      ‘No. I think you are fully human. This is to be admired.’

      He felt awkward again. He’d
