Criptonomicon II : El Codigo Pontifex

In 1942, Lawrence Pritchard Waterhouse, mathematical genius and captain in the U.S. Navy, is assigned to Detachment 2702, whose mission is to keep Nazis ignorant of the fact that Allied Intelligence cracked the enemy's fabled Enigma code. Sixty years later, Waterhouse's crypto-hacker grandson, Randy, is attempting to create a data haven where encrypted data can be stored and exchanged free of scrutiny. Soon his scheme brings to light a massive conspiracy that originated with Detachment 2702, one that represents either a future of personal and digital liberty or universal totalitarianism reborn.
