Gather information from society girl on raging fire (7)
I believe the answer is:
debrief
'gather information from' is the definition.
(eg debriefing a secret agent)
'society girl on raging fire' is the wordplay.
'society girl' becomes 'deb' (I've seen this before).
'on' is an insertion indicator.
'raging' indicates anagramming the letters.
'fire' anagrammed gives 'rief'.
'deb' put inside 'rief' is 'DEBRIEF'.
(Other definitions for debrief that I've seen before include "Question (returning spy)" , "Question (soldier) after a mission" , "Get follow-up report" , "Gather information from returning agent" , "Gather information from (a soldier) after operation" .)
