Paul spoke without blinking, and still softly, though the clamour around had grown. He was young but, Hepton knew, not an idiot. A first in astrophysics from Edinburgh, then research in Australia. No idiot, but not a hands-on expert either. It was his job – his sole responsibility and specialism – to monitor the space around Zephyr, seeking space trash, debris, meteorites, waves of interference. He’d never made a mistake when it had counted. Never.

‘Okay, Paul,’ Hepton said. ‘Give me a couple of minutes to put things right and I’ll come take a look.’

‘Thanks.’ Vincent looked relieved, like a man who needs reassuring that those pink elephants he can see really are there. Maybe they were, at that. He left Hepton’s side and returned to his distant console. Then again, maybe the kid was losing his touch. There had been a bout of sulking a week ago to do with some girlfriend or other. Hazard of the job. Shift work, odd hours, occasional days on end cooped up in the base. Sleeping four to a room in two sets of bunk beds. Hepton wasn’t sure he could take much more of it himself, despite the pleasures of earth-watching. Who ever thought to ask him if he were lonely? Nobody. He thought of Jilly, and wondered what she was doing while he sat here. He didn’t want to think what she was doing.

The brass were looking pleased about something. Well, they’d got Zephyr back, hadn’t they? One said something to the other, and Hepton, watching the man’s lips move, caught the words ‘three minutes forty’. The other nodded and smiled again. So they were discussing the length of time the satellite had been lost to its ground base. Three minutes and forty seconds. Longer than ever before. Almost too long.

Things were calming down all around. Fagin had gone to speak with the brass. They were in a huddle now, their eyes glinting. Hepton couldn’t see their lips any more. Well, it was none of his concern. He busied himself with putting his console right. He had pushed a few too many of the wrong buttons in the wrong sequences. Adjustments were needed. And then he would visit Paul Vincent on the other side of the room.

‘More coffee?’ It was Nick Christopher.

‘You put sugar in the first.’

‘An honest mistake. I’ll fetch you another.’

‘Don’t bother. What do you think went wrong back there?’

‘Put it down to a hiccup. Everything malfunctions from time to time. Between the two of us, I think Zephyr was cobbled together like its namesake, the old car. We’ll be lucky if it stays the course.’

‘It was out for three minutes forty seconds.’

‘What?’

‘The brass were timing it.’

‘Then maybe it was an exercise.’

‘I don’t think Paul Vincent would agree.’

‘Martin, you’re talking in riddles.’

‘Sorry.’

‘Now what about that coffee?’

‘No sugar this time?’
