Historians gathered at Warwick this summer to celebrate the contribution of Christopher Andrew.
When did the study of secret intelligence become a recognised field for historians? The consensus at a conference held at Warwick University in July was 1984, with the publication of The Missing Dimension: Governments and Intelligence Communities in the Twentieth Century by Professor Christopher Andrew and his colleague David Dilks.
The occasion was a festschrift and cohors amicorum for Andrew, the doyen of espionage historians. It brought together former students and intelligence officers to mull over the pros and cons of throwing light on secret operations.
