Abstract

After World War I, the International Communism Movement, led by the Third International the Comintern' was one of the major threats to the British Empire. TheComintern constructed a worldwide liaison network of comrades called the CominternNetwork to try to penetrate the "Western World." In order to police this CominternNetwork, the British Empire constructed its own Security System consisting of theIntelligence Service the Political Intelligence Bureau or the Special Branch and thePassport Control System. This paper uses "the Lefranc Affair" as a case study todemonstrate how the British Security System policed the Comintern Network, particularlyin Asia. A French agent of the Comintern named Serge Lefranc, alias Joseph Ducroux, whoworked in Asia from 1926, was arrested in Singapore on 1 June 1931. This paper describeshow the British Security System monitored his activities and took action against him, andsummarizes the structure of the British Security System by focusing on cooperationbetween the Intelligence Service and the Passport Control System.
