Rong Jinzhen, an autistic math genius with a past shrouded in myth, is forced to abandon his academic pursuits when he is recruited into Unit 701: a top-secret Chinese intelligence agency whose sole purpose is counterespionage and code-breaking. As China´s greatest cryptographer, Rong discovers that the mastermind behind the maddeningly difficult Purple Code is his former teacher and best friend, who is now working for China´s enemy but this is only the first of many betrayals.
The first novel to be published in English by one of China´s greatest contemporary writers, "Decoded" is a riveting tale of obsession and a profound exploration of the mind of an inspired genius, one that discovers in cryptography the key to the human heart."
