A history of the British Special Operations Executive published very shortly before MRD Foot's "SOE In France". Initially, for reasons of security, Mr Cooke was not given access to government files in Britain; so he instead started with human contacts (a distinguished list of names is given) in both Britain and abroad; finding much relevant information in files abroad.
E. H. Cookridge was himself, for a time, a prisoner at Dachau and Buchenwald.
He used several other pseudonymns, including Peter Leighton, Peter Morland, Ronald Reckitt and Edward H Spire along with probably his most famous, E H Cookridge.
As Cookridge, he wrote his first book 'Secrets of the British Secret Service' in 1948 and this contained 'some highly coloured versions of true events'.
Most of his works under the Cookridge pseudonymn are concerned with spies and spying, including books on George Blake and Kim Philby.
