The bestselling puzzle book series is back with a whole new twist on a treasure hunt. A follow up to the bestselling 2018 & 2019 Ordnance Survey Puzzle Books, the Ordnance Survey Great British Treasure Hunt is here with puzzles based on 40 brand new maps stretching the entirety of Britain. In this edition you will find various puzzles to solve with good ol’ Aunt Bea, as she takes her nephew on a voyage of discovery around our Isles. All maps are 25k OS Explorer extracts and highlight where our pair stop off on their adventure. Those who are adventurous, love the outdoors, and have a thirst for knowledge, will love this book. Each map has a key puzzle, and once solved you’ll be able to work out the final location of the treasure! Unlike its predecessors, the 2020 edition has taken the notes pages, condensed them, and moved them to the back of the book — giving more room for information, photos, and wonderous illustrations. There’s also a foreword from BBC Countryfiles’ Julia Bradbury. Once you\'ve solved the puzzle go to www.ospuzzlebook.co.uk and enter your answer to the Lock Puzzle for your chance to win real prizes.
