“We haven't done anything wrong,” said the kid. “Not here, anyway.”

“You never know, with governments. Just sit still here, kid. I'll take a look.”

People did look at Maurice when he stalked into the building, but it seemed that in a town beset by rats a cat was quite popular. A man did try to pick him up, but lost interest when Maurice turned and clawed the back of his hand.

The queue wound into a big hall and passed in front of a long trestle table. There, each person showed their piece of paper to two women in front of a big tray of bread, and were given some bread. Then they moved on to a man with a vat of sausages, and got considerably less sausage.

Watching over all this, and occasionally saying something to the food servers, was the mayor. Maurice recognized him instantly because he had a gold chain around his neck. He had run across a lot of mayors since working with the rats. This one was different from the rest. He was smaller, far more worried, and had a bald spot that he'd tried to cover with three strands of hair. He was a lot thinner than other mayors Maurice had seen, too. He didn't look as if he'd been bought by the ton.

So… food is scarce, Maurice thought. They're having to ration it out. Looks like they'll be, needing a piper any day now. Lucky for us we arrived just in time…

He walked out again, but this time a bit faster, because he realized that someone was playing a pipe. It was, as he feared, the kid. He'd put his cap on the ground in front of him, and had even accumulated a few coins. The queue had bent round so that people could hear him, and one or two small children were actually dancing.

Maurice was only an expert on cat singing, which of standing two inches in front of other cats and screaming at them until they give in. Human music always sounded thin and watery to him. But people tapped their feet when they heard the kid play. They smiled for a while.
