Hogfather - Time

'The rat said you ought to be warned even if you were crazy,' said the raven sulkily. 'I didn't want to come, there's a donkey dropped dead just outside the city gates, I'll be lucky now if I get a hoof-- -’

'Warned?' said Susan.

There it was again. The change in the weather of the mind, a sensation of tangible time...

The Death of Rats nodded.

There was a scrabbling sound far overhead. A few flakes of soot dropped down the chimney.

SQUEAK, said the rat, but very quietly.

Susan was aware of a new sensation, as a fish might be aware of a new tide, a spring of fresh water flowing into the sea. Time was pouring into the world.

She glanced up at the clock. It was just on half past six.

The raven scratched its beak.

'The rat says... The rat says: you'd better watch out . . .’
