The Emperor's Codes: The Breaking of Japan's Secret Ciphers
During World War II, British and American cryptographers labored  in tight security at Bletchley Park and elsewhere, poring over  thousands of intercepted Japanese and German military messages.  This fascinating story has been told and retold over the past 15  years as more new information emerges. Smith, a British  journalist and author of Station X: Decoding Nazi Secrets, has  now expanded on the subject with this well-written account of  how the Americans with a great deal of help from British  codebreakers cracked the Japanese codes. Smith portrays the  sometimes bitter competition between American naval and British  military personnel and insists that the British deserve a  greater share of the credit than the Americans have been willing  to grant. All in all, it makes a great story and one of  importance, since many historians believe that through their  codebreaking efforts the Allies were able to shorten the war by  as much as two years. Libraries should add Smith's book to other  recent works, including Stephen Budiansky's Battle of Wits (LJ  9/15/00) and Leo Marks's Between Silk and Cyanide (LJ 4/15/99).
