On the day when things came to a head there had been a sudden fall of dark toffee, extremely precious and very unusual, but feared by every treacle miner because of its tendency to spontaneously collapse into the tunnels. According to the eyewitnesses, both humans and dwarfs were mining underground while politicians argued on both sides of the political divide. And this fall was mostly on the human side of the seam, with many men trapped in a deluge of unrelenting stickiness.

He hesitated for a moment and said, ‘Or it might have been the dwarf side, now I come to think about it …’ He looked embarrassed, but continued. ‘Well, it doesn’t really matter now who they were, it was a long time ago anyway. The miners working the seam from the other side of the fall heard that there were many miners down there, trapped and drowning in refined sugar derivatives, and said, “Come on, lads, get the gear together and let’s get them out of there.”’

The old boy hesitated a further moment, possibly for effect, and said, ‘But of course that meant that they had to enter territory that required going through two bloody security barriers manned by armed guards. Guards, moreover, who were not that bothered about miners and were certainly not going to let any of the enemy down into their sovereign soil.’

Another significant pause, then the tale raced on. All the miners had piled up against the barriers. Someone said, ‘We can’t tackle them, they’ve got weapons!’ and they looked at one another in what is known as wild surmise, and then another voice yelled, ‘But so have we, when you look at it the right way, and ours are bigger!’ And the speaker waved his enormous fist and said, ‘And we’re mining every day, not standing around and looking smart.’

And so as one dwarf, or possibly human, they rushed the barricade and the guards, realizing they were failing to frighten people, ran for cover as the miners with the picks and shovels came down on them at speed and sixty miners were saved from a very sticky situation on both sides of the seam.

Nothing official happened afterwards because officialdom didn’t want any part of the shame of it.

The old boy looked around and glowed as if he himself had been one of those miners and, quite possibly, he might have been, and his tankard was topped up once again and he said wistfully, ‘Of course, that was the old days. I wish it still was.’

It was just short of the end of the second day when Simnel and his lads had Iron Girder chuffing slowly and purposefully along a short circular track in Harry’s compound.

And Harry couldn’t help noticing that the look of the engine had changed and it now seemed somehow … smoother than before. In fact, he thought, he had been ready to say sleek, though it was hard to think of what looked like fifty tons of steel as sleek, but yes, he thought, why not? It shouldn’t be beautiful, but she was. Stuttering, stinking, growling, smoking, but so very beautiful.
