She brings company into line, possibly (6)
I believe the answer is:
nicole
'she' is the definition.
(I've seen this before)
'company into line possibly' is the wordplay.
'company' becomes 'co' (abbreviation).
'into' is an insertion indicator.
'possibly' indicates an anagram.
'line' is an anagram of 'nile'.
'co' placed within 'nile' is 'NICOLE'.
'brings' acts as a link.
(Other definitions for nicole that I've seen before include "-- Kidman, actress" , "girl" .)
