Alongside the open conflict of World War II there were other, hidden wars - the wars of communication, in which success depended on a flow of concealed and closely guarded information.

Smuggled written messages, secretly transmitted wireless signals, or months of eavesdropping on radio traffic meant operatives could discover in advance what the enemy intended to do.

This information was passed on to those who commanded the armies, the fleets and the bomber formations, as well as to the other secret agents throughout the world who were desperately trying to infiltrate enemy lines.

Vital information that turned the tide of battle in North African desert and on the Pacific Ocean proved to have been obtained by the time-consuming and unglamorous work of cryptanalysts who deciphered the enemy's coded messages, and coded those for the Allies.
