"But things are looking up," said Vimes. "Dee has discovered a new pronoun, even if he does spit it."
"Sam!" said Lady Sybil, advancing through the throng, "they"re going to perform Bloodaxe and Ironhammer! Isn"t that wonderful?"
"Er..."
"It"s an opera, sir," Cheery whispered. "Part of the Koboldean Cycle. It"s history. Every dwarf knows it by heart. It"s about how we got laws, and kings... and the Scone, sir."
"I sang the part of Ironhammer when we did it at finishing school," said Lady Sybil. "Not the full five-week version, of course. It"ll be marvellous to see it done here. It"s really one of the great romances of history."
"Romances?" said Vimes. "Like... a love story?"Yes. Of course."
"Bloodaxe and Ironhammer were both... er... weren"t both..." Vimes began.
"They were both dwarfs, sir," said Cheery.
"Ah. Of course." Vimes gave up. All dwarfs were dwarfs. If you tried to understand their world from a human point of view it all went wrong. "Do, er, enjoy it, dear. I"ve got to... The King wants me to... I"ll just be somewhere else for a while. Politics..."
He hurried away, with Cheery trailing behind him.
Dee led the way through dark tunnels. When the opera began it was a whisper far away, like the sea in an ancient shell.
Eventually they stopped at the edge of a canal, its waters lapping at the darkness. A small boat was tethered there, with a waiting guard. Dee urged them into it.
"It is important that you understand what you are seeing, your grace," said Dee.
"Practically nothing," said Vimes. "And I thought I had good night vision."
There was a clink in the gloom, and then a lamp was lit. The guard was punting the boat under an arch and into a small lake. Apart from the tunnel entrance, the walls rose up sheer.
"Are we at the bottom of a well?" said Vimes.
"That is quite a good way of describing it." Dee fished under his seat. He produced a curved metal horn and blew one note which echoed up the rock walls.
After a few seconds another note floated down from the top. There was a clanking, as of heavy, ancient chains.
"This is quite a short lift compared to some up in the mountains," said Dee, as an iron plate ground across the entrance, sealing it. "There"s one half a mile high that will take a string of barges."
Water boiled beside the boat. Vimes saw the walls begin to sink.
"This is the only way to the Scone," said Dee behind him.
Now the boat was rocking in the bubbling water and the walls were blurred.
"Water is diverted into reservoirs up near the peaks. Then it is simply a matter of opening and closing sluices, you see?"
"Yes," mumbled Vimes, experiencing vertigo and seasickness in one tight green package.
The walls slowed. The boat stopped shaking. The water lifted them smoothly over the lip of the well and into a little channel, where there was a dock.
"Any guards below?" Vimes managed, stepping out on to the blessedly solid stone.
"There are usually four," said Dee. "For tonight I... arranged matters. The guards understand. No one is proud of this. I must tell you, I disapprove most strongly of this enterprise."
Vimes looked around the new cave. A couple of dwarfs were standing on a lip of stone that overlooked what was now a placid pool. By the look of it, they were the ones who operated the machinery.
"Shall we proceed?" said the dwarf.
There was a passage leading off the cave, which rapidly narrowed. Vimes had to bend almost double along one length. At one point metal plates clanked under his feet, and he felt them shift slightly. Then he was standing almost upright again, passing under another arch, and there...
