Once again deal with hiding place (7)
I believe the answer is:
retreat
'hiding place' is the definition.
(thesaurus)
'once again deal' is the wordplay.
'once again' becomes 're' (I've seen this in other clues).
'deal' becomes 'treat' (I've seen this before**).
're'+'treat'='RETREAT'
'with' is the link.
(Other definitions for retreat that I've seen before include "What cowards might do" , "Tree rat (anag)" , "Monastery - bugle call" , "hermitage, perhaps" , "Withdraw from battle" .)
