Read Henry Hemming’s account of Maxwell Knight’s life as Britain’s greatest spy and far-sighted, influential naturalist of his day:

‘Fascinating… Hemming has done a superb job’ – Ben Macintyre, The Times, Book of the Week

“Maxwell Knight was a paradox. A jazz obsessive and nature enthusiast (he is the author of the definitive work on how to look after a gorilla), he is seen today as one of MI5’s greatest spymasters, a man who did more than any other to break up British fascism during the Second World War – in spite of having once belonged to the British Fascisti himself. He was known to his agents and colleagues simply as M, and was rumoured to be part of the inspiration for the character M in the James Bond series.”
