Triple Mirror

The story begins in the late autumn of 1931. Fang Jueming, an intelligence officer of the CCP Special Branch, discovers that everyone around him could be the Japanese spy codenamed 'Baku'—Old K left an unfinished name in his palm before dying, and his deputy Xiao Meng smiles with concern but keeps his right hand in his pocket. Forced to 'defect', he uses the blood of his own people to gain the enemy's trust, walking a bloody path with no end in sight. There is always a pair of eyes watching him from behind, every step like treading on knife edges. Fang Jueming successfully infiltrates the Japanese Mei Agency, and cooperates with Kuomintang agent Shen Hanzhou (Bai Hong) from suspicion and wariness to tacit understanding. During the eight years of the War of Resistance, they passed intelligence in the dark and documented evidence of the Nanjing Massacre; after the war, with the KMT-CCP confrontation, she handed him the list of undercover agents and went overseas, lurking beside the real 'Baku' for years. Letters with only one line, sent from Hong Kong, Tokyo, and Taipei, continued for decades. She never returned and her whereabouts remain unknown. 'Triple Mirror' is not only a spy novel but also an elegy for the nameless heroes of the covert front. In the triple mirror, you cannot see yourself, but history will eventually see you. Open it, step into those turbulent years, and feel the weight of faith. — Description from novelcodex.org
