between the European powers, with the Nazi regime seeking to exploit anticolonialists against Britain and France, while Britain and France worked more closely together to maintain their empires, seeing the threat from both the anticolonialists and the Nazis. The narrative of the book ends in 1945, with the defeat of Nazi Germany, but new challenges faced by the victorious Allies. Many of those anti-colonial activists monitored in Europe from the 1920s to the 1940s travelled to the colonies, taking part in national liberation struggles. In the era of decolonisation and the Cold War, Britain and France relied on the intelligence networks that had been developed over the previous half century. Policing Transnational Protest is a pioneering work in two ways. Firstly it brings together a history of policing activists and ‘subversives’ across Western Europe, exploring the co-operation between British, French and German agencies to monitor cross-border activity. Secondly it shifts the focus away from solely examining the period leading up to the First World War (which is the scope for most similar studies of transnational policing) and onto the inter-war period, as well as the Second World War. Daniel Brückenhaus has produced a valuable transnational study for scholars interested in the history of counter-terrorism and counter-subversion, which will be sure to inspire further studies on the interconnectedness of policing networks in the twentieth century.
