Back in his cabin, Cormac called up a view into Isolation and watched the dracomen eat yet another meal. Could it have been them? he wondered. Somehow that did not seem Dragon’s style. It was possible, but why would Dragon do such a thing? Why would Dragon want the people of Samarkand killed? Or perhaps he was asking the wrong question. Why would Dragon want the Samarkand runcible destroyed? He shook his head. There was not yet enough evidence to put any theories together.

‘Hubris, any luck with that submind?’

The AI’s reply was quick and succinct. ‘I do not have the capacity to spare for it at the moment.’

‘The mycelium?’

‘Two-thirds of my capacity is being used for decoding it and designing a counteragent.’

‘OK, can you put me through to the submind?’

‘Yes.’

‘—throw away archetypes but keep ideas bathwater baby hell hath no hungry mole lord of pain lord of pain where is edge? Sinter snapping hove to green rotting fruit—’

Running his finger down a touch-strip Cormac turned the sound down. He said to the submind, ‘The runcible buffers were destroyed by a nanomycelium.’

He turned the sound back up.

‘—hungry hungry eater green green grass is green fell into the rainy day bleed break men lizard Janus—’

Men lizard?

‘Who destroyed the runcible buffers?’

‘—gain gone flee on invisible wings rotting fruit blackthorn thorns peach—’

Cormac clicked the voice off. For a moment he thought he had something there, but would the runcible AI have known who planted the mycelium? It seemed unlikely. Had it known, it would have transmitted more information before its destruction. Had it known, it would have instantly shut down the runcible. Freeman might have ended up lost in underspace, but that would have been better than him causing the deaths of 10,000 people.

‘Hubris, show me that mycelium in the shuttle bay.’

The picture on the screen changed. There was no word from the AI. Perhaps it was getting impatient with him. He stared at the picture. Even with part of the deck cut away the shape of the dull footprints was evident. They were long and splayed, with a mark for a back toe; obviously not human and obviously the footprints of dracomen, but was that damning evidence? Anyone who had been to the surface could have carried some of the mycelium away with them. The dracomen had been there longer, so it was more likely to be them.

‘Hubris, the dracomen brought the mycelium aboard.’

‘Already aware.’

Cormac rattled his fingers on his desk.

What now?
