Following on from the very successful Enigma, Enigma 2 brings another 170 puzzles to those who are clamouring for more brain-teasers, games of logic, conundrums, riddles, paradoxes and word games to challenge, perplex and entertain them.The entire book has the feel and appearance of a medieval manuscript, full of secret knowledge, that has emerged unexpectedly from a deep vault in an ancient library. More than just a book of puzzles, it's a visual and cerebral feast to treasure in any library.
