In planning this book and arranging its evidence I have been guided by the social anthropologist Sir Edward Evans-Pritchard. ‘Events lose much, even all, of their meaning if they are not seen as having some degree of regularity and constancy, as belonging to a certain type of event, all instances of which have many features in common,’ he wrote. ‘King John’s struggle with the barons is meaningful only when the relations of the barons to Henry I, Stephen, Henry II, and Richard are also known; and also when the relations between the kings and barons in other countries with feudal institutions are known.’ Similarly, the intelligence services’ dealings with the Cambridge ring of five are best understood when the services’ relations with other spy networks working for Moscow are put alongside them. The significance of Kim Philby, Donald Maclean, Guy Burgess, Anthony Blunt and John Cairncross, and the actions of counter-espionage officers pitted against them, make sense only when they are seen in a continuum with Jack Hayes, Norman Ewer, George Slocombe, Ernest Oldham, Wilfrid Vernon, Percy Glading, Alan Nunn May, William Marshall and John Vassall.
Enemies Within is a set of studies in character: incidentally of individual character, but primarily a study of institutional character. The operative traits of boarding schools, the universities of Oxford and Cambridge, the Intelligence Division, the Foreign Office, MI5, MI6 and Moscow Centre are the book’s subjects. Historians fumble their catches when they study individuals’ motives and individuals’ ideas rather than the institutions in which people work, respond, find motivation
