To destroy SPECTRE in “For Your Eyes Only” (3,6)
I believe the answer is:
top secret
'for your eyes only' is the definition.
I know nothing about this answer so I can't judge whether this works.
'to destroy spectre' is the wordplay.
'destroy' indicates anagramming the letters (I've seen this in other clues).
'spectre' with letters rearranged gives 'psecret'.
'to'+'psecret'='TOP-SECRET'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for top secret that I've seen before include "Highly confidential" , "Highest classified (information)" , "(Of information) strictly not for public consumption" , "the knack of sleeping well?" , "Highly classified" .)
