The book we are discussing is by Brian Clegg
, a well-known author of books on math and science -- but this is not exactly a book on math or science, although these subjects play a significant role. His latest book is Conundrum: Crack the Ultimate Cipher Challenge
(Icon Books, 2019), which should delight and intrigue not only those who love math and science, but those who love solving puzzles. This book is a literary escape room, with a series of puzzles to be solved, all of which contribute to a final puzzle that concludes the book. And like the clues one finds in an escape room, Brian mercifully offers hints for the puzzles.
