Hawker originally flies a recluse across Cape (8)
I believe the answer is:
falconer
'hawker' is the definition.
(synonyms)
'originally flies a recluse across cape' is the wordplay.
'originally' suggests taking the first letters.
'recluse' becomes 'loner' (I've seen this before).
'across' is an insertion indicator.
'cape' becomes 'c' (abbreviation used on maps).
The first letter of 'flies' is 'f'.
'loner' placed around 'c' is 'lconer'.
'f'+'a'+'lconer'='FALCONER'
(Other definitions for falconer that I've seen before include "Trainer of hunting hawks" , "Trainer of birds of prey" , "Person who breeds and trains hawks" , "Bird-keeper" , "Someone who hunts with birds of prey" .)
