No scope for this, uncovered by detective (5,3)
I believe the answer is:
naked eye
'no scope' is the definition.
'naked eye' can be an answer for 'scope' (thesaurus). I'm unsure of the 'no' bit.
'this uncovered by detective' is the wordplay.
'this uncovered' becomes 'naked' (I've seen this in another clue).
'by' is a charade indicator (letters next to each other).
'detective' becomes 'eye' (as in a private eye).
'naked'+'eye'='NAKED EYE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for naked eye that I've seen before include "Unaided vision" , "It doesn't need a visual aid to see" , "(View) unaided by any optical instrument" , "Unassisted vision" , "With which to observe" .)
