As the title of this biography implies, Airey Neave's spent much of his life at the interface between two worlds, those of politics and intelligence. His career went through several intriguing phases. each of which sheds light on the history of Britain's secret state.
A visit to Germany as a 17-year-old Etonian in 1933 gave Neave an early hatred for fascism. In the 1930s, when many of his colleagues at Oxford were turning to socialism and even communism, he began a lifelong interest in the Territorial Army.
By 1940, he was a young army lieutenant, fighting in the bloody, and ultimately doomed, defence of Calais. His capture by the German paved the way for the defining period of his life.
