Scout in story, small boy at Hogwarts after set of books (6,7)
I believe the answer is:
talent spotter
'scout' is the definition.
(I've seen this before)
'story small boy at hogwarts after set of books' is the wordplay.
I cannot really see how this works, but
'story' could be 'tale' (synonyms) and 'tale' is found within the answer.
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found within the answer.
'of' could be 'o' and 'o' is found within the answer.
'books' could be 'nt' (New Testament) and 'nt' is located in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for talent spotter that I've seen before include "Agent looking for the gifted" , "One looking for good new performers" , "Show business scout" .)
