Ness of "The Untouchables" (5)
I believe the answer is:
eliot
'ness of the untouchables' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eliot that I've seen before include "T.S. or George?" , "Pseudonymous writer" , "Middlemarch author" , "Practical Cats author" , "T S . . . . . wrote ''The Waste Land''" .)
