Mastermind in Greene novel (8)

Ross

I believe the answer is:

engineer

'mastermind' is the definition.
('engineer' can be a synonym of 'mastermind')

'in greene novel' is the wordplay.
'novel' is an anagram indicator.
'in'+'greene'='ingreene'
'ingreene' with letters rearranged gives 'ENGINEER'.

(Other definitions for engineer that I've seen before include "One who designs, makes or runs motors" , "Skilfully arrange" , "Applied technologist" , "Practical technologist" , "Person who uses scientific knowledge to solve practical problems" .)

I've seen this clue in The Telegraph.
