Most Secret Agent of Empire

the long version

"Compelling biography of Reginald Teague-Jones (1889- 1988) -- the most important British spy you have never heard of. Teague-Jones was feared by Stalin, roamed Eurasia and chameleon-like, vanished, only to reappear in America, decades later, still practicing espionage. Teague-Jones was held responsible for the execution of 'the 26 Commissars' after the fall of the Baku Commune in 1918 - an event that inspired a poem by Yesenin, a Brodsky painting and a 1933 feature film."--Publisher's website
