Masson"s extraordinary secret channel to Berlin was not, of course, the only Swiss intelligence operation during the war. Braunschweig outlines in detail the gradual build-up, tasks and functions of Swiss Intelligence during World War II. Furthermore, he describes conflicts between Swiss Intelligence and the Federal government in Bern and within the Intelligence service itself. During World War II, Switzerland was famous as a centre of spies and espionage fielded by Allies and Axis alike. Less has been known, however, about Switzerland"s own Intelligence activities, including its secret sources in Hitler"s councils and its counterespionage program at home. With this intensely researched, scholarly yet exciting book, that gap in the history of wartime intelligence operations has been filled.
