{"product_id":"cambridge-theorem-book-tony-cape-9780385264907","title":"The Cambridge Theorem","description":"When Simon Bowles commits suicide, no one is surprised. A graduate student in mathematics at Cambridge University, Bowles had a long, well-documented history of depression. But as Detective Sergeant Derek Smailes soon discovers, he also had a passion for investigating historical mysteries and an extraordinary knack for solving them. His most recent project: uncovering the identity of the fabled fifth man in the notorious Cambridge spy-ring of the 1930s. Could Bowles possibly have solved that mystery? And could his solution - his theorem - have brought about his death? Rooted in the (thoroughly researched) history of the Cambridge Spies.","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50289167859985,"sku":"CIN0385264909G","price":3.98,"currency_code":"USD","in_stock":true},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51423740363025,"sku":"CIN0385264909VG","price":4.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0385264909.jpg?v=1751165646","url":"https:\/\/www.worldofbooks.com\/products\/cambridge-theorem-book-tony-cape-9780385264907","provider":"World of Books ","version":"1.0","type":"link"}
