Questioned to get instructions in deed (9)
I believe the answer is:
debriefed
'questioned' is the definition.
(debriefing is a kind of questioning)
'instructions in deed' is the wordplay.
'instructions' becomes 'brief' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'brief' going inside 'deed' is 'DEBRIEFED'.
'to get' is the link.
Can you help me to learn more?
(Other definitions for debriefed that I've seen before include "Gathered info on return from a mission, from a soldier say" , "Questioned after completing a mission" .)
