Reviews

‘This extraordinary book does for MI6 what Mr West did for MI5, the internal security service, in a controversial history…In both of them the reader is presented with dozens, possibly hundreds of names of intelligence officers and agents, details of major intelligence operations with code-names and case histories, organizational charts and much mores besides’
