Trick receiver of stolen goods, assuming I had courage (10)
I believe the answer is:
confidence
'courage' is the definition.
(I've seen this before)
'trick receiver of stolen goods assuming i had' is the wordplay.
'trick' becomes 'con' (I've seen this before).
'receiver of stolen goods' becomes 'fence' (I've seen this before).
'assuming' indicates putting letters inside.
'i had' becomes 'id' (I'd).
'fence' going around 'id' is 'fidence'.
'con'+'fidence'='CONFIDENCE'
(Other definitions for confidence that I've seen before include "communication of faith" , "conviction" , "Shared secret - belief" , "courage" , "belief in one's own abilities" .)
