Newton back in Africa as investigative journalist? (5)
I believe the answer is:
isaac
'newton' is the definition.
(synonyms)
'back in africa as investigative journalist?' is the wordplay.
'back' shows that the letters should be reversed in order.
'in' indicates the answer is hidden within the clue.
'caasi' can be found hidden inside 'africa as investigative journalist'.
'caasi' backwards is 'ISAAC'.
(Other definitions for isaac that I've seen before include "Biblical father of twins" , "Youth almost sacrificed" , "designated victim" , "Stern" , "Jacob's father" .)
