Codenamed WALLFLOWERS, this is one of the Security Service's most treasured possessions, the daily journal dictated from August 1939 to June 1945 by MI5's Director of Counter-Espionage, Guy Liddell. It was considered so sensitive that it was highly classified and retained in the safe of successive Directors-General, with special permission required to read it.
