In the winter of 1936, Gu Shuanzhu, the third-class patrol officer in the French Concession in Shanghai, discovered a body in a dead alley. The deceased held a train ticket to Nanjing and a notebook full of passwords in his arms.
Following the numbers inside, he reached the basement of a Japanese restaurant where the arms ledger stored by the Japanese in the French Concession was hidden. Without saying anything, he took a copy of the account book, took a few gold bars, and set a fire to burn the basement.
From then on it was out of control. During the day, he was the most inconspicuous Chinese policeman in the patrol room. At night, he climbed over walls, picked locks, followed, and counter-tracked. He copied the code book of Japanese spies, rescued an underground party from the backyard of the gendarmerie, and after the fall of Shanghai, he changed his name and surnamed and lurked in Hongkou for a year and a half. Every time he solves a case, he can take something from the scene - gold bars, pistols, information. Promotion, wealth, and equipment all depend on "gifts" from the Japanese.
A cool story about the spy war of the Republic of China. A low-level policeman made a fortune quietly in the undercurrent of Shanghai and caught spies.
