Text tells the story of Frank B. Rowlett, a codebreaker whose work was done for years before and during World War II in deepest secrecy.
Although dozens of cryptographic systems of both friends and enemy were broken, the greatest triumph was perhaps that of breaking the Japanese PURPLE diplomatic cipher machine, the machine used for transmission of Japan's most secret and sensitive diplomatic messages before and after the entrance of the United States into World War II. Adding greatly to the book is its Foreword and Epilogue, written by David Kahn, author of The Codebreakers. Text includes pictures.
