Bamber Gascoigne's Challenging Quiz Book
I imagine quite a few people reading this will have come across Bamber Gascoigne's Challenging Quiz Book before. In essence, the book aims to challenge even the finest quizzers with a range of well-written, original and fun questions. Plenty to be learned and a wide range of testing questions. In a book of this size you can normally discount 30-50% of the questions as mere filler, but the opposite is true here with very few "chestnuts". In all an excellent title!
