Meeting Pop in a way was being a prying observer (7,3)
I believe the answer is:
peeping tom
'observer' is the definition.
(Peeping Tom is an example)
'meeting pop in a way' is the wordplay.
'in a way' is an anagram indicator.
'meeting'+'pop'='meetingpop'
'meetingpop' is an anagram of 'PEEPING TOM'.
'was being a prying' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for peeping tom that I've seen before include "Voyeur" , "who likes looking at females" , "One who spies pruriently on others" , "Spy" .)
