Decoded tells the story of Rong Jinzhwen, one of the great code-breakers in the world.

A semi-autistic mathematical genius, Jinzhen is recruited to the cryptography department of China's secret services, Unit 701, where he is assigned the task of breaking the elusive 'Code Purple'. Jinzhen rises through the ranks to eventually become China's greatest and most celebrated code-breaker; until he makes a mistake. Then begins his descent through the unfathomable darkness of the world of cryptology into madness.

'Decoded is a subtle and complex exploration of cryptography, politics, dreams and their significance...There is much of interest in this book, from the strange, superstitious beginning to the gradual decline of the Rong family as the twentieth century progresses...But in the end, it's the complexity of the characters that is Decoded's enduring pleasure' London Review of Books

Decoded was an immediate success when it was published in 2002 in China and has become an international bestseller. With the pacing of a literary crime thriller, Mai Jia's masterpiece also combines elements of historical fiction and state espionage. Taking place in the shadowy world of Chinese secret security, where Mai Jia worked for decades, it introduces us to a place that is unfamiliar, intriguing and authentic. And with Rong Jinzhen, it introduces us to a character who is deeply flawed and fragile, yet possessing exceptional intelligence. Decoded is an unforgettable and gripping story of genius, brilliance, insanity and human frailty.
