Title in This Set :. Bletchley Park Brainteasers The biggest selling quiz book of 2017 by Sinclair McKay. Condition : BRAND NEW. Format : Paperback. ISBN : 9781472252609. Description :. When scouring the land for top-level code breakers, the Bletchley Park recruiters left no stone unturned. As well as approaching the country's finest mathematicians, they cast their nets much wider, interviewing sixth-form music students who could read orchestral scores, chess masters, poets, linguists, hieroglyphics experts and high society debutantes fresh from finishing school. To assess these individuals they devised various ingenious mind-twisters - hidden codes, cryptic crosswords, secret languages, complex riddles - and it is puzzles such as these, together with the fascinating recruitment stories that surround them, that make up the backbone of this book.
