The Killer Cat's Christmas by Anne Fine The killer cat is causing Christmas chaos! 'Dear, dear Tuffy, why was your Christmas so horrible?' Tuffy isn't allowed to climb the tree and he's supposed to star in Ellie's silly Christmas show. Horrible, horrible, horrible! And, thanks to Mr Grumpy, somehow Tuffy ends up in a cupboard. Just two big staring eyes in the dark, hiding from everyone. Christmas is meant to be so merry. But this year, at Tuffy's house, it all ends up a giant great mess.
