Revolutionary closely looked to gather count's hiding place (4,4)

I believe the answer is:

dead drop

I'm a little stuck... Click here to teach me more about this clue!

'place' is the definition.
(I know that dead drop is a type of drop)

'revolutionary closely looked to gather count's hiding' is the wordplay.
I cannot quite understand how this works, but
'count' could be 'add' (adding is a kind of counting) and 'add' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
