Corso sighed and gripped her by the shoulders, forcing her to look at him directly. ‘There’s no way you could have known beforehand what was going to happen, and Nancy knew the risks before she came along on this trip. We all did. You understand that, right?’

Dakota looked away from him again. ‘Maybe.’

‘Maybe, yes,’ he said. ‘Now listen, there’s something we need to talk about. Something urgent.’

She glanced back at him. ‘What?’

‘The closer we get to where we’re going, the more nervous I get when it comes to letting Trader anywhere near the Mos Hadroch. But I just got back from seeing Nathan Driscoll over in the labs – and it looks like he’s finally on to something.’

‘A way to activate it?’

Corso hesitated. It had already occurred to him that there was no reason to assume Whitecloud was the only one to have been compromised.

‘No, not yet,’ he replied, entirely aware of how evasive he was sounding. ‘Something else.’

Her eyes narrowed as she studied his face. ‘Oh, for . . . You still don’t trust me, do you? Listen, I already checked myself out before Olivarri was murdered. I went down to the med-bay and ran a full set of diagnostics on my implants almost as soon as we were under way, because I wanted to be sure. Lamoureaux did the same, and he’s never even met Trader. Believe me,’ she continued, ‘we’re both clean, and neither of us is being controlled – not by Trader or anyone else.’

‘Why the hell didn’t you tell me this before now?’

‘Because, after Olivarri was murdered, I knew it wouldn’t make the slightest damn bit of difference what I said. You read the report on the med-bay; whoever did the vandalizing, they didn’t just smash the physical scanners, they did a good job of wiping the core memory as well. So how could either of us prove that we’d scanned ourselves?’

‘All right, I’m sorry for doubting you. Anyway, Nathan now thinks it’s possible there’s a close relationship between the swarm and the Atn. He thinks one might have split off from the other a very long time ago and, given what he just showed me, I’m inclined to believe it.’

Dakota’s eyes widened. ‘Shit, that’s . . .’ She tailed off into silence.

‘Pretty incredible, yeah,’ Corso finished for her, then he nodded towards the exit. ‘Maybe we should get going.’

Dakota followed him to the nearest transport station. ‘I’ve run into Atn a couple of times on coreships,’ she said, as they boarded a car. ‘They’re harmless, so it’s hard to believe they could somehow be related to something as malign as the swarm.’
