{"product_id":"lady-or-the-tiger-book-raymond-m-smullyan-9780192801432","title":"The Lady or the Tiger?","description":"This text presents a series of logic puzzles, ranging from the simplest problems to the most tantalizing complexities. An array of imaginary characters - sane and insane vampires, psychiatrists, dreamers, hermits, kings, knights and knaves - pose questions, giving just enough information to enable the reader to solve problems of increasing difficulty. The final section of the book, \"The Mystery of the Monte Carlo Lock\", is a mathematical novel. Beginning with the problem of finding a combination to open a safe, Inspector Craig of Scotland Yard finds himself in ever deeper mathematical waters, which lead eventually to the very heart of Godel's revolutionary theory of undecidability.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49572704813329,"sku":"GOR003035300","price":7.99,"currency_code":"GBP","in_stock":false},{"title":"GB \/ WELL_READ \/ INTERNAL","offer_id":51907849847057,"sku":"GOR002050324","price":7.1,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0192801430.jpg?v=1750972693","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/lady-or-the-tiger-book-raymond-m-smullyan-9780192801432","provider":"World of Books ","version":"1.0","type":"link"}
