Girl in papers upset by gossip (5)
I believe the answer is:
diana
'girl' is the definition.
'papers upset by gossip' is the wordplay.
'papers' becomes 'id' (identification papers).
'upset' says the letters should be written backwards.
'by' says to put letters next to each other.
'gossip' becomes 'ana' (I have seen 'literary gossip' mean 'ana' so perhaps 'gossip' could also mean 'ana').
'id' reversed gives 'di'.
'di'+'ana'='DIANA'
'in' is the link.
(Other definitions for diana that I've seen before include "Girl's name; goddess" , ""The People's Princess"" , "Girl" , "Roman goddess of the hunt, or tragic English princess" , "Roman huntress goddess" .)
