Brilliant IQ Puzzles by Arcturus Publishing, exercise for brains, those little grey cells need to be looked after. I have a few quiz, puzzle, logic puzzles for sale and will be happy to combine postage. Unfortunately these books are of great quality and so are heavy ( this one is 450g so postage is £2.15). Two books will cost just a £1 more and the third book does not cost anything. From a smoke and pet free home
