Book Description
December, 1932 In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents – the operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lays the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover-name 'X, Y & Z'. December, 1942 It is the middle of World War Two. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland. Now they are on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone, so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, the consequences could be catastrophic for the Allies. Based on original research and newly released documents, X, Y & Z is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.

Book Description
A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912–1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades—all before his suicide at age forty-one. This New York Times bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing’s royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936—the concept of a universal machine—laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program—all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

Book Description
Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book will tell the whole Enigma story: the original invention and use by German forces and how it was the Poles who first cracked, and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable. Hugh Sebag-Montefiore - like his brother Simon a journalist and author - has unearthed files at the Ministry of Defence and further documents now declassified in the US. He has also traced and made contact with many of the last surviving witnesses to the Enigma story, including Paul Pailliole, who was head of French counterintelligence and has a detailed first hand knowledge of the spying and double crossing which took place in relation to Enigma.

Book Description
Here is the first complete account of the incredible intelligence war fought for the mastery of Enigma, the code used by mose branches of the German armed forces in World War II. Beginning ten full years before the eruption of hostilities in September 1939 and increasing in intensity throughout the war, the Engima war was won by the Allies through the success of Ultra, the Allied codebreaking operation at Bletchley Park, England. Ultra remained until recently one of the best-kept secrets of World War II. --

WOULD BLETCHLEY PARK--THE TOP-SECRET HOME OF BRITISH WORLD WAR II CODEBREAKERS--HAVE RECRUITED YOU? PUT YOUR MENTAL AGILITY TO THE TEST WITH THESE FIENDISHLY CHALLENGING PUZZLES AND FIND OUT. Have a knack for mastering Morse code? Want to discover whether your crossword hobby might have seen you recruited into the history books? Think you could have contributed to the effort to crack the Nazis' infamous Enigma code? Then this book about Bletchley Park was custom-made for you. When scouring the population for codebreakers, Bletchley Park recruiters left no stone unturned. They devised various ingenious mind-twisters to assess the puzzle-solving capacity of these individuals--hidden codes, cryptic crosswords, secret languages, and complex riddles. These puzzles, together with the fascinating recruitment stories that surround them, are contained in this book, endorsed by Bletchley Park itself. Though they had diverse backgrounds, the codebreakers of Bletchley Park were united in their love of a good puzzle. If you are of the same persuasion, put your intelligence to the test with the mind-boggling puzzles on these pages and ask yourself: Would Bletchley Park have recruited YOU?

Book Description
An eminent psychiatrist delves into the minds of Nazi leadershipin “a fresh look at the nature of wickedness, and at our attempts to explain it” (Sir Simon Wessely, Royal College of Psychiatrists). When the ashes had settled after World War II and the Allies convened an international war crimes trial in Nuremberg, a psychiatrist, Douglas Kelley, and a psychologist, Gustave Gilbert, tried to fathom the psychology of the Nazi leaders, using extensive psychiatric interviews, IQ tests, and Rorschach inkblot tests. The findings were so disconcerting that portions of the data were hidden away for decades and the research became a topic for vituperative disputes. Gilbert thought that the war criminals’ malice stemmed from depraved psychopathology. Kelley viewed them as morally flawed, ordinary men who were creatures of their environment. Who was right? Drawing on his decades of experience as a psychiatrist and the dramatic advances within psychiatry, psychology, and neuroscience since Nuremberg, Joel E. Dimsdale looks anew at the findings and examines in detail four of the war criminals, Robert Ley, Hermann Göring, Julius Streicher, and Rudolf Hess. Using increasingly precise diagnostic tools, he discovers a remarkably broad spectrum of pathology. Anatomy of Malice takes us on a complex and troubling quest to make sense of the most extreme evil. “In this fascinating and compelling journey . . . a respected scientist who has long studied the Holocaust asks probing questions about the nature of malice. I could not put this book down.”—Thomas N. Wise, MD, Johns Hopkins University School of Medicine “This harrowing tale and detective story asks whether the Nazi War Criminals were fundamentally like other people, or fundamentally different.”—T.M. Luhrmann, author of How God Becomes Real

Book Description
“An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).
