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 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.

Mai Jia (the pseudonym of Jiang Benhu) is arguably the most successful writer in China today. His books are constant bestsellers, with total sales over three million copies. He became the highest paid author in China last year with his new book, Wind Talk. He has achieved unprecedented success with film adaptation: all of his novels are made - or are being made - into major films or TV series, the screenplays of which are often written by Mai Jia himself. He is hailed as the forerunner of Chinese espionage fiction, and has created a unique genre that combines spycraft, code-breaking, crime, human drama, historical fiction, and metafiction. He has won almost every major award in China, including the highest literary honor - the Mao Dun Award.
