A depicter of English rural life, he brought down Al Capone (5)
I believe the answer is:
eliot
I believe this is a double definition.
'a depicter of english rural life' is the first definition.
(T.S. Eliot, 1888-1965)
'he brought down al capone' is the second definition.
(Eliot Ness, 1903-1957)
(Other definitions for eliot that I've seen before include "Four Quartets poet" , "T S . . . . . wrote ''The Waste Land''" , "T S . . . . ., great poet of 'The Waste Land'" , "Middlemarch author" , "Practical Cats author" .)
