In August 1937, Gu Huaian was just a Japanese censor at the Shanghai Postal Administration. After his cousin was taken away from the police station, someone handed him a document and said, "After turning this over, your cousin will come back."
He turned over and could never get out again.
Three forces, three identities, seven years. He works as a Japanese document specialist in Wang Puppet's intelligence department, delivering news to the military commander. There is another line that no one knows about. Every night he returned to the pavilion, wrote down what he had remembered during the day, burned it, and continued the next day.
There was only one person who accompanied him to the end - the female reporter who was originally ordered to monitor him. Later, she became his upline, and later, she became the only person he didn't have to make up stories about.
