Paddington, to his surprise, finds all the Browns holding a party in his honour. Mr. Gruber gives him a book "One hundred ways of tearing paper". Paddington consults the book - the first item is "The mystery of the disappearing banknote". He borrows a note from Mr. Curry and tears bits out of it - it is supposed to turn up in Mr. Curry's ear but Paddington had turned to the wrong page and has made a paper doily.
