In front of the agent I had to be fearless (8)
I believe the answer is:
intrepid
'be fearless' is the definition.
('intrepid' can be a synonym of 'fearless')
'in front of the agent i had' is the wordplay.
'front of' indicates taking the first letters.
'agent' becomes 'rep' (short for representative).
'i had' becomes 'id' (I'd).
The first letter of 'the' is 't'.
'in'+'t'+'rep'+'id'='INTREPID'
'to' acts as a link.
(Other definitions for intrepid that I've seen before include "Bold" , "Novel" , "stout" , "'Brave, dauntless (8)'" , "Audacious" .)
