Tramp taking Independent papers (7)
I believe the answer is:
dossier
'papers' is the definition.
(thesaurus)
'tramp taking independent' is the wordplay.
'tramp' becomes 'dosser' (dosser is a kind of tramp).
'taking' means one lot of letters goes inside another.
'independent' becomes 'i'.
'dosser' placed around 'i' is 'DOSSIER'.
(Other definitions for dossier that I've seen before include "File of documents" , "A collection of papers" , "Set of papers" , "Collection of documents on a subject" , "Report" .)
