Short indeed, being questioned (9)
I believe the answer is:
debriefed
'questioned' is the definition.
(debriefing is a kind of questioning)
'short indeed' is the wordplay.
I cannot really understand how this works, but
'short' could be 'brief' (similar in meaning) and 'brief' is located in the answer.
The remaining letters 'deed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'being' is the link.
Can you help me to learn more?
(Other definitions for debriefed that I've seen before include "Questioned after completing a mission" , "Gathered info on return from a mission, from a soldier say" .)
