Rent report (5)
I believe the answer is:
crack
I believe this clue is a double definition.
'rent' is the first definition.
(thesaurus)
'report' is the second definition.
(thesaurus)
(Other definitions for crack that I've seen before include "Ace" , "Take severe measures - . . . . . down on" , "Opening; sharp blow" , "Narrow opening, break" , "Joke; split" .)
