If he’d kept his promise to Greta, would those seven instrument builders be alive now? And if the Council had been able to keep the messaging system secret, would its impact on ordinary people’s lives have ended up being less intrusive? Maybe there would have been a violent backlash when word of its existence finally leaked out – or maybe the foreknowledge that the system granted would have been enough to prevent that.

But he’d made his choice, and now he had to take some share of responsibility for the way things had unfolded. All his feelings of shame and sadness were just useless self-indulgence, though, if he did nothing more than stare into the past and wish that everything could have been different.

The only question now was: where did this end? Ramiro had had no news from outside since his arrest, but he suspected that the strike had been called off, as a gesture of respect to the grieving relatives. That would be the right thing to do, but it wouldn’t resolve anything. So long as the messaging system was still being built, almost half the population would remain disaffected – and the change being forced on them wasn’t something they could learn to live with. It made no difference how he felt, himself; he could renounce the killers as loudly as he liked, he could give up the fight and embrace his enemies. There would never be peace in the mountain again.

And was that it? The situation was unsalvageable?

He reached out for a rope and raised his torso off the bed, the tarpaulin crinkling around him. There would never be a consensus, but that didn’t mean there had to be violence. He was never going to be reconciled with Corrado, but so long as no one locked them in the same room together they weren’t going to kill each other.

What if they partitioned the Peerless and let the messagers and anti-messagers live apart – dividing the resources of the mountain in proportion to the votes? Those who chose to live without the system need never cross paths with those who used it.

The trouble was, there’d be people on both sides who wouldn’t be satisfied with their share of living space. The messagers might find ways to use their foreknowledge to manipulate their neighbours – and even if they didn’t, the possibility would be enough to drive the kind of fanatics who’d bombed the camera workshop to keep on trying to destroy the whole system.

Ramiro looked out across the darkness. Maps and treaties would never be enough. Locked doors and solid stone walls couldn’t separate the two groups so completely as to end their mutual fear and suspicion.

The only cure was distance.
