Spent years breaking into deserted tourist attraction (6,3)
I believe the answer is:
london eye
'tourist attraction' is the definition.
(the London Eye is a tourist attraction)
'spent years breaking into deserted' is the wordplay.
'spent' becomes 'done' (I've seen this in another clue).
'years breaking' becomes 'y' (I can't explain this - if you can you should believe this answer much more).
'into' means one lot of letters goes inside another.
'deserted' becomes 'lone'.
'done'+'y'='doney'
'doney' placed inside 'lone' is 'LONDON EYE'.
Can you help me to learn more?
(Other definitions for london eye that I've seen before include "Millennium tourist attraction" , "Big Thames wheel" , "South Bank attraction" , "Wheel with views of capital" , "Thames tourist attraction" .)
