Conan Doyle hero - name set to enthral one (5)
I believe the answer is:
nigel
'conan doyle hero' is the definition.
I can't tell whether this definition defines the answer.
'name set to enthral one' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'set' becomes 'gel' (both can mean to harden).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'enthral one' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'gel' put after 'i' is 'igel'.
'n'+'igel'='NIGEL'
Can you help me to learn more?
(Other definitions for nigel that I've seen before include "Man's name" , "--- Pargetter, (Archers)" , "We all sign on (anag) -- politician" , "boy" , "-- Kennedy, violinist" .)
