Hogfather - Librarian

The Librarian pulled the blankets over himself and curled up. As an orang-utan he hankered for the warmth of the rainforest. The problem was that he'd never even seen a rainforest, having been turned into an orang-utan when he was already a fully grown human. Something in his bones knew about it, though, and didn't like the cold of winter at all.

But he was also a librarian in those same bones and he flatly refused to allow fires to be lit in the library. As a result, pillows and blankets went missing everywhere else in the University and ended up in a sort of cocoon in the reference section, in which the ape lurked during the worst of the winter. He turned over and wrapped himself in the Bursar's curtains.

There was a creaking outside his nest, and some whispering.

'No, don't light the lamp.'
