The big red sun was moving through bars of cloud.

"Oh, let him, dear, if it gives the poor soul any pleasure," said Lady Sybil, shutting the window. "Now, Sam, what happened at the tower?"

"I don't really want to worry you, Sybil..."

"Well, now that you've got me really really worried, you may as well tell me. All right?" worried, you may as well tell me. All right?"

Vimes gave in and explained the little that he knew.

"Someone's killed them?"

"Possibly."

"The same people that ambushed us back in that gorge?"

"I don't think so."

"This isn't turning out to be much of a holiday, Sam."

"It's not being able to do do anything that makes me sick," said Vimes. "Back in Ankh-Morpork...well, I'd have leads, contacts, some kind of a map. Everyone here is...well, hiding something, I think. The new king thinks I'm a fool, the werewolves treated me as if I was something the cat dragged in...the only person who's been halfway civil was a vampire!" anything that makes me sick," said Vimes. "Back in Ankh-Morpork...well, I'd have leads, contacts, some kind of a map. Everyone here is...well, hiding something, I think. The new king thinks I'm a fool, the werewolves treated me as if I was something the cat dragged in...the only person who's been halfway civil was a vampire!"

"Not the cat," said Sybil.

"What?" said Vimes, mystified.

"Werewolves hate cats," said Sybil. "I distinctly remember that. Definitely not cat people."

"Hah. No. Dog people. They don't like words like bath or vet bath or vet, either. I reckon if you threw a stick at the baron he'd leap out of his chair to catch it-"

"I suppose I ought to tell you about the carpets," said Sybil, as the coach rocked around a corner.

"What, isn't he house-trained?"

"I meant the carpets in the emba.s.sy. You know I said I'd measure up for them? But the measurements aren't right, on the first floor..."

"I don't want to sound impatient, dear, but is this a carpet moment?"

"Sam?"

"Yes, dear?"

"Just stop thinking like a husband and start listening like a...a copper, will you?"

Vimes marched into the emba.s.sy and summoned Detritus and Cheery.

"You two are coming with us to the ball tonight," he said. "It'll be posh. Have you got anything to wear apart from your uniform, Sergeant?"

"No, sir."

"Well, go and see Igor. There's a good man with a needle if I ever saw one. How about you, Cheery?"

"I do, er, have a gown," said Cheery, looking down shyly.

"You do?"

"Yes, sir."

"Oh. Well. Good. I'm putting the two of you on the emba.s.sy staff, too. Cheery, you're...you're Military Attache."

"Oh," said Detritus, disappointed.

"And, Detritus, you're Cultural Attache."

The troll brightened up considerably. "You will not regret dis, sir!"

"I'm sure I won't," said Vimes. "Right now, I'd like you to come with me."

"Is dis a cultural matter, sir?"

"Broadly. Perhaps."

Vimes led the troll and Sybil up the stairs and into the office, where he stopped in front of a wall.

"This one?" he said.

"Yes," said his wife. "It's hard to notice until you measure the rooms, but that wall really is rather thick-"

Vimes ran his hands along the paneling, looking for anything that might go click click. Then he stood back.

"Give me your crossbow, Sergeant."

"Here we are, sir."

Vimes staggered under its weight, but managed to get it pointed at the wall.

"Is this wise, Sam?" said Sybil.

Vimes stood back to take aim, and the floorboard moved under his heel. A panel in the wall swung gently.

"You scared der h.e.l.l out of it, sir," said Detritus loyally.

Vimes carefully handed the crossbow back, and tried to look as though he'd meant things to happen this way.

He'd expected a secret pa.s.sage. But this was a tiny workroom. There were jars on shelves, with labels...NEW SUET STRATA, AREA 21, 21, GRADE A FAT, THE BIG HOLE GRADE A FAT, THE BIG HOLE. There were lumps of crumbling rock, with neat cardboard tags attached to them saying things like LEVEL LEVEL #3, #3, SHAFT SHAFT 9, 9, DOUBLE-PICK MINE DOUBLE-PICK MINE.

There was a set of drawers. One of them was full of makeup, including a selection of mustaches.

Wordlessly, Vimes opened one of a stack of notebooks. The first pages had a pencil drawn street map of Bonk, with red lines threading through it.

"Good grief, look at this," he breathed, flicking onward. "Maps. Drawings. There's pages of stuff about the a.s.saying of fat deposits. Huh, says here '...the new suets, while initially promising, are now suspected of having high levels of BCBs and are likely to be soon exhausted.' And here here it says 'A werewolf putsch is clearly planned in the chaos following the loss of the Scone'...'K. reports that many of the younger werewolves now follow W., who has changed the nature of the Game'...This stuff...this stuff is it says 'A werewolf putsch is clearly planned in the chaos following the loss of the Scone'...'K. reports that many of the younger werewolves now follow W., who has changed the nature of the Game'...This stuff...this stuff is spying spying. I wondered how Vetinari always seems to know so much!"

"Did you think it came to him in dreams, dear?"

"But there's loads of details here...notes about people, lots of figures about dwarf mining production, political rumors...I didn't know we did this sort of thing!"

"You use spies all the time, dear," said Sybil.

"I do not!"

"Well, what about people like Foul Ole Ron and No Way Jose and c.u.mbling Michael?"

"That is not not spying, that is spying, that is not not spying! That's just 'information received.' We couldn't do the job if we didn't know what's happening on the street!" spying! That's just 'information received.' We couldn't do the job if we didn't know what's happening on the street!"

"Well...perhaps Havelock just thinks in terms of...a bigger street, dear."

"There's loads more of this muck, look. Sketches, more bits of ore...what the h.e.l.l's this?"

It was oblong, and about the size of a cigarette packet. There was a round gla.s.s disk on one face, and a couple of levers on one side.

Vimes pushed one of them. A tiny hatch opened on one side, and the smallest head that he'd ever seen that could speak said "'s?"

"I know dat!" said Detritus. "Dat's a nano-imp! Dey cost over a hundred dollars! Dey're really small small!"

"No one's b.l.o.o.d.y fed me for a fortnight!" the imp squeaked.

"It's an iconograph small enough to fit in a pocket pocket," said Vimes. "Something for a spy...it's as bad as Inigo's d.a.m.n one-shot crossbow. And look..."

Steps led downward. He took them carefully, and swung open the little door at the end.

Wet heat slapped into him.

"Pa.s.s me down a candle, will you, dear?" he said. And by its light he looked out into a long dank tunnel. Crusted pipes, leaking steam at every joint, lined the far wall.

"A way in and out where no one will see him, too," he said. "What a dirty world we live in..."

The clouds had covered the sky and the wind was whipping thick snowflakes around the tower when Inigo finished setting up the red mortar on the platform below the big square shutters.

He lit a couple of matches but the wind streamed them out before he could even cup his hands around them.

"d.a.m.n. Mmm, mmm."

He slid down the ladder and into the warmth of the tower. It'd be better to spend the night here, he thought, as he rummaged in drawers. The night didn't hold many terrors for him, but this storm had the feel of another big snow and the mountain roads would soon be treacherous.

Finally an idea struck him, and he opened the door of the stove and pulled out a smoldering log on the tongs.

It burst into flame when he carried it out at the top of the tower, and he directed them into the touch hole at the base of the tube.

The mortar fired with a phut phut that was lost in the wind. The flare itself tumbled invisibly up into the snow and then, a few seconds later, exploded a hundred feet overhead, casting a brief red glare over the forests. that was lost in the wind. The flare itself tumbled invisibly up into the snow and then, a few seconds later, exploded a hundred feet overhead, casting a brief red glare over the forests.

Inigo had just gotten back into the room when there was a knock at the door, down at ground level.

He paused. There was a window and hatch at this level; the designers of the tower had at least realized that it would be a good idea to be able to look down and see who was a-knocking.

There was no one there.

When he'd climbed back into the room, the knock came again.

He hadn't locked the door after Vimes went. A bit late to regret that now, he realized. But Inigo Skimmer had trained in an academy that made the School of Hard Knocks look like a sandpit.

He lit a candle and crept down the ladder in the darkness, shadows fleeing and dancing among the stacks of provisions.

With the candle set down on a box, he pulled the one-shot crossbow from inside his coat and, with an effort, c.o.c.ked it against the wall. Then he flexed his left arm and felt the palm dagger ease itself into position.

He clicked his heels in a certain way and sensed the tiny blades slide out from the toes.

And Inigo settled down to wait.

Behind him, something blew the candle out.

As he turned, and the crossbow's one bolt whirred into darkness, and the palm dagger scythed at nothing, it occurred to Inigo Skimmer that you could knock on either either side of a door. side of a door.

They really were were very clever... very clever...

"Mhm, m-"

Cheery twirled, or at least attempted to. It was not a movement that came naturally to dwarfs.

"You look very...nice," said Lady Sybil. "It goes all the way to the ground, too. I don't think anyone could possibly complain."

Unless they were remotely fashion conscious, she had to admit.

The problem was that the...well, she had to think of them as the new new dwarf women-hadn't quite settled on a look. dwarf women-hadn't quite settled on a look.

Lady Sybil herself usually wore ball gowns of a light blue, a color often chosen by ladies of a certain age and girth to combine the maximum of quiet style with the minimum of visibility. But dwarf girls had heard about sequins. They seemed to have decided in their bones that, if they were going to overturn thousands of years of subterranean tradition, they weren't going to go all through that for no d.a.m.n twin-set and pearls.

"And red is good good," said Lady Sybil sincerely. "Red is a very nice color. It's a nice red dress. Er. And the feathers. Er. The bag to carry your ax, er-"
