Gently interrogate clue for 'Flee' (4,3)

'gently interrogate clue' is the definition.
I can't tell whether this defines the answer.

'flee' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'flee' is 'feel' which is located in the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'for' acts as a link.

Can you help me to learn more?
