Alix Yin Fu belongs to the White Tigers, a secret triad that joins the Communist secret services to help New China. Alix, the adopted daughter of the famous Zizhu Tigress, carries out missions for Kang Sheng, head of these services. In a background of espionage, Conrad and Wilbur transport us with humour and charm in a China drawn between the nationalists of Chiang Kai-Shek and the Communists of Mao.
