Sensational expat scandals - Telegraph French diplomat Bernard Boursicot fell foul of a Chinese honeypot trap in the 1960s, when he became infatuated with Shi Pei Pu, a male Peking opera singer who he believed to be female. Over two decades later, Boursicot was arrested by French authorities for espionage, and sentenced to six years in prison. The play and film M Butterfly (1993, pictured) were based on the affair.
