Man in Eden (4)
I believe the answer is:
adam
'man in eden' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for adam that I've seen before include "Fellow" , "expelled gardener" , "__ Smith, author of The Wealth of Nations" , "Robert -, Sc. architect" , "Father of Cain and Abel" .)
