Famed outlaw Kelly stores books (5)
I believe the answer is:
noted
'famed' is the definition.
(synonyms)
'outlaw kelly stores books' is the wordplay.
'outlaw kelly' becomes 'ned' (outlaw Ned Kelly. I am not sure about the 'outlaw' bit.).
'stores' means one lot of letters goes inside another.
'books' becomes 'ot' (Old Testament).
'ned' going around 'ot' is 'NOTED'.
Can you help me to learn more?
(Other definitions for noted that I've seen before include "Remarkable" , "Wrote it down" , "saw" , "Observed - recorded" , "written down" .)
