Bonnet for this rascal? (4)
I believe the answer is:
hood
I believe this clue is a double definition.
'bonnet' is the first definition.
(I know that bonnet can be written as hood)
'this rascal?' is the second definition.
(thesaurus)
'for' is the link.
(Other definitions for hood that I've seen before include "See 13" , "Outlaw and gangster" , "Bronx district" , "Thomas -, Eng. poet" , "Protective cover - violent criminal (slang)" .)
