Mai plays adroitly with literary genre and crafts a story of Borgesian subtlety and complexity.--The New Yorker

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.
