Geeks Guide₂ For the third edition of our Geeks Guide₂ feature we go behind the scenes of World War II and tell the story of the infamous code breakers and the stealth-like role they played throughout the war.

Voices of the Code Breakers by Michael Paterson delves into the world of covert war and reveals how much of World War II was in fact won away from the battlefield. While the news reports of the time concentrated on the physical battles being fought, hidden wars of communication were taking place. This week's GG₂ book provides us with an enlightening account of the extraordinary people from the British Cryptologists to the Navajo Indians and their chance finds, lucky accidents, resolute determination, and how their moments of sheer brilliance helped win their war. The secretly transmitted wireless signals, smuggled written messages and months of snooping on radio traffic that allowed operatives to provide crucial knowledge of the enemy's plans to military commanders is all documented.

Paterson also treats us to a first-rate look at the use of the computer during World War II, how the code breakers used it to spectacular effect and the subsequent development based on its successes. We get first-hand accounts from the staff of Bletchley Park, American secret agents, French and Dutch resistance fighters, and members of the Services Liaison Unit who passed on the vital coded information to field commanders. It also includes a 16-page plate section with rare archive photographs.
