He could try the dracomen again, but his last attempt at communication had tried his patience to the limit. He was sure they were quite capable of speaking with him in some manner, but one of them just sat there and grinned while the other just sat staring at the food dispenser. Perhaps what he needed was face to face, rather than gestures through the viewing window and speech through the intercom.

‘Damn it!’

He stood up and headed for Isolation.

As he came from the drop-shaft Cormac saw that Mika was standing before the viewing window to the isolation chamber. She stood in an attitude of deep contemplation, an elbow cupped in one hand and her other hand under her chin. Standing like that she appeared less of a girl. Or was he seeing her differently now? He wondered how old she was. She could be anywhere from eighteen to 300 years. Appearance had not been a way to judge age for the last four centuries. He walked up beside her. She did not acknowledge his presence until he was two paces from her.

‘Ah, Ian Cormac.’

‘Just Cormac. Something bothering you?’

‘No, not really—not bothering me. I’m just intrigued. I did some checking.’ She pointed to the floor of the isolation chamber by the far wall. ‘You see those?’

Cormac looked across and saw what appeared to be a couple of screwed-up polythene bodysuits. He looked from them to the two dracomen, who were squatting motionless in the middle of the chamber, and noticed that they appeared cleaner, brighter.

‘Skins,’ he said. ‘They shed their skins.’

‘They’ve done it three times since they were put in here. They’re regenerating: sloughing off and excreting radiation-damaged cells, and rapidly replacing them.’

‘Yes, Hubris told me.’

She glanced at him. ‘Did it also tell you that they are also immune to cancer, to replication error?’

‘A handy trait, but it is also one we have.’

‘Yes, but ours is done by viral or nanomachine repair of our DNA based on the corrected birth blueprint. We still develop cancers and they still have to be cured. This is completely different.’

‘I don’t know whether or not it is relevant, but, as well as it being proposed that dracoman was one of the race Dragon claimed to represent, it was also proposed that he was some kind of organic machine.’

‘We are all organic machines. No, you miss my point . . . I analysed some of that skin. They are without DNA. They replace cells by direct protein replication. It’s been done before, but no creature has ever evolved that method. Far too complex.’

‘So they are some kind of machine?’

‘If you want to call them that. Philosophy is not my field.’

Cormac felt a twinge of embarrassment. ‘I guess that was a stupid thing to say.’
