Fed German without hesitation (1-3)
I believe the answer is:
g-man
'fed' is the definition.
(I've seen this before)
'german without hesitation' is the wordplay.
'without' indicates named letters should be taken away.
'hesitation' becomes 'er' (sound used when hesitating).
'german' with 'er' taken away is 'G-MAN'.
(Other definitions for g-man that I've seen before include "FBI agent" , "Officer of the FBI in USA" .)
