In the Dark

More about the book

'Cracking another country's cipher is an undercover fight to the death...' Hidden deep in the mountains, the recruits at 'Unit 701', China's secret services, operate in a dark, shadowy world. There is the 'wind-listener', a blind surveillance officer who can hear sounds from miles away; the beautiful, unstable maths genius who meets a violent end; the old man who deciphers codes in his dreams; the spy who recounts a dangerous mission from beyond the grave. In this story of conspiracies, geniuses, revolutionaries and terrible moral choices, people sacrifice everything for a world of secrets - until, ultimately, it destroys them.
