Arrangement of Abbey Road rightly overlooking a ridiculously high cost (8,7)
I believe the answer is:
daylight robbery
'ridiculously high cost' is the definition.
The definition suggests a singular noun which matches the answer.
'arrangement of abbey road rightly overlooking a' is the wordplay.
'arrangement of' is an anagram indicator.
'overlooking' is a deletion indicator.
'abbey'+'road'+'rightly'='abbeyroadrightly'
'abbeyroadrightly' with 'a' taken out is 'bbeyroadrightly'.
'bbeyroadrightly' with letters rearranged gives 'DAYLIGHT ROBBERY'.
Can you help me to learn more?
(Other definitions for daylight robbery that I've seen before include "Scandalous" , "as shoplifting usually is" , "Blatant overcharging" , "A shameless swindle" , "audacious act of exploitation" .)
