He'd drawn lines and squiggles on the floor.

“Hrumph. I can see them, but I don't have to know what they are,” said Hamnpork. He rubbed his nose. “I've never needed any more than this.”

Darktan gave a patient sigh. “Then smell, sir, that this is a… a picture of all the tunnels we've explored today. It's… the shape I have in my head. We've explored a lot of the town. There's a lot of the…” he glanced at Peaches, “a lot of the kind traps, mostly empty. There's poison all over the place. It's mostly quite old. Lots of empty live traps. Lots of killer traps, still set. And no live rats. None at all, except for our… new friend. We know there's something very odd. I sniffed around a bit near where I found her, and I smelled rats. Lots of rats. I mean lots.”

“Alive?” said Dangerous Beans.

“Yes.”

“All in one place?”

“It smells that way,” said Darktan. “I think a squad should go and look.”

Dangerous Beans got closer to the rat and sniffed at her again. The rat sniffed at him. They touched paws. The watching Changelings were astonished. Dangerous Beans was treating the keekee as an equal.

“Lots of things, lots of things,” he murmured. “Many rats… humans… fear… lots of fear… lots of rats, crowded… food… rat… you said she's been eating rat?”

“It's a rat-eat-rat world,” said Hamnpork. “Always has been, always will be.”

Dangerous Beans wrinkled his nose. “There's something else. Something… odd. Strange… she's really scared.”

“She has been in a trap,” said Peaches. “And then she met us.”

“Much…worse than that,” said Dangerous Beans. “She's… she's frightened of us because we're strange rats but she smells relieved that we're not… what she's used to…”

“Humans!” Darktan spat.

“I… don't… think… so…”

“Other rats?”

“Yes… no… I… don't… it's hard to tell…”

“Dogs? Cats?”

“No.” Dangerous Beans stepped back. “Something new.”

“What shall we do with her?” said Peaches.

“Let her go, I suppose.”

“We can't do that!” said Darktan. “We've triggered all the traps we've found but there are still poisons all over the place. I wouldn't send a mouse out into that lot. She hasn't tried to attack us, after all.”

“So?” said Hamnpork. “What's another dead keekee?”

“I know what Darktan means,” said Peaches. “We can't just send her out to die.”

Big Savings stepped forward and put a paw around the young female, cuddling her protectively. She glared at Hamnpork. Although she might nip him sometimes if she was annoyed, she wouldn't argue with him. She was too old to do that. But her look said: all males are stupid, you stupid old rat.

He looked lost. “We've killed keekees, haven't we?” he said sadly. “Why do we want this one hanging around?”

“We can't send her out to die,” said Peaches again, looking at Dangerous Beans' expression. He had that faraway look in his pink eyes.

“You want it trailing around eating our food and messing things up?” said Hamnpork. “It can't talk, it can't think…”

“Nor could we, not long ago!” snapped Peaches. “We were all like her!”

“We can think now, young female!” said Hamnpork, his hair rising.

“Yes,” said Dangerous Beans quietly. “We can think. We can think about what we do. We can pity the innocent one who means us no harm. And that's why she can stay.”

Hamnpork's head turned sharply. Dangerous Beans was still facing the newcomer. Hamnpork reared up instinctively, a rat ready to fight. But Dangerous Beans couldn't see him.

Peaches watched the old rat with concern. He'd been challenged, by a weedy little rat who would not last a second in a fight. And Dangerous Beans hadn't even realized he'd made the challenge.

He doesn't think like that, Peaches told herself.

The other rats were watching Hamnpork. They still thought like that, and were waiting to see what he would do.

But it was dawning even on Hamnpork that pouncing on the white rat would be unthinkable. It would be like cutting off his own tail. He very carefully let himself relax. “It's just a rat,” he muttered.

“But you, dear Hamnpork, are not,” said Dangerous Beans. “Will you go with Darktan's crew to find out where she came from? It could be dangerous.”

This made Hamnpork's hair rise again. “I'm not afraid of danger!” he roared.

“Of course not. That is why you should go. She was terrified,” said Dangerous Beans.

“I've never been scared of anything!” shouted Hamnpork.

Now Dangerous Beans turned to face him. In the candlelight there was a glow in the pink eyes. Hamnpork was not a rat who spent a lot of time thinking about things he couldn't see or smell or bite, but…

He looked up. The candlelight made big rat shadows dance on the wall. Hamnpork had heard the young rats talking about shadows and dreams and what happened to your shadow after you died. He didn't worry about that stuff. Shadows couldn't bite you. There was nothing to be frightened of in shadows. But now his own voice in his head told him I'm frightened of what those eyes can see. He glared at Darktan, who was scratching something in the mud with one of his sticks.

“I'll go, but I will lead the expedition,” he said. “I'm senior rat here!”

“That doesn't worry me,” said Darktan. “Mr Clicky is going to be going in front in any case.”

“I thought he got smashed last week?” said Peaches.

“We've got two left,” said Darktan. “Then we'll have to raid another pet shop.”

“I'm the leader,” said Hamnpork. “I'll say what we do, Darktan.”

“Fine, sir. Fine,” said Darktan, still drawing in the mud. “And you know how to make all the traps safe, do you?”

“No, but I can tell you to!”

“Good. Good,” said Darktan, making more marks with his stick and not looking at the leader. “And you'll tell me which levers to leave alone and which bits to wedge open, will you?”

“I don't have to understand about traps,” said Hamnpork.

“But I do, sir,” said Darktan, speaking in the same calm voice. “And I'm telling you that there's a couple of things about some of these new traps I don't understand, and until I understand them I'd very respectfully suggest you leave it all to me,”

“That is not the way to talk to a superior rat!”

Darktan gave him a look, and Peaches held her breath.

This is the showdown, she thought. This is where we find out who is the leader.

Then Darktan said, “I am sorry. Impertinence was not intended.”

Peaches picked up the astonishment amongst the older males who were watching. Darktan. He'd backed down! He hadn't leapt!

But he hadn't cowered back, either.

Hamnpork's fur settled. The old rat was at a loss to know how to deal with this. All the signals were mixed up.

“Well, er…”

“Obviously, as the leader you must give the orders,” said Darktan.

“Yes, er…”

“But my advice, sir, is that we investigate this. Unknown things are dangerous.”

“Yes. Certainly,” said Hamnpork. “Yes, indeed. We will investigate. Of course. See to it. I am the leader, and that is what I am saying.”

Maurice looked around at the inside of the rat-catchers' shed.

“It looks like a rat-catchers' shed,” he said. “Benches, chairs, stove, lots of rat skins hanging up, piles of old traps, a couple of dog muzzles, rolls of wire netting, considerable evidence of a lack of any dusting ever being done. It's what I'd have expected a rat-catchers' hut to look like inside.”

“I was expecting something… horrible yet interesting,” said Malicia. “Some ghastly clue.”

“Does there have to be a clue?” said Keith.

“Of course!” said Malicia, looking under a chair. “Look, cat, there's two types of people in the world. There are those who have got the plot, and those who haven't.”

“The world hasn't got a plot,” said Maurice. “Things just… happen, one after another.”
