Hindu somehow gets round island as a stunt man (7)
I believe the answer is:
houdini
'a stunt man' is the definition.
(I know this)
'hindu somehow gets round island' is the wordplay.
'somehow' indicates an anagram.
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'round' becomes 'o' (round can mean a round object).
'island' becomes 'i' (geographical abbreviation).
'hindu' anagrammed gives 'hudin'.
'hudin' going around 'o' is 'houdin'.
'houdin'+'i'='HOUDINI'
'as' acts as a link.
(Other definitions for houdini that I've seen before include "Escape artist, d. 1926" , "one who'd try to escape?" , "Expert at escaping" , "US magician and escapologist, 1874-1926" , "Showman" .)
