Attractive victims come round time after time (6)
I believe the answer is:
pretty
'attractive' is the definition.
(I've seen this before)
'victims come round time after time' is the wordplay.
'victims' becomes 'prey' (I can't explain this - if you can you should give a lot more credence to this answer).
'come round' is an insertion indicator.
'time' becomes 't' (abbreviation).
'after' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
't' after 't' is 'tt'.
'prey' enclosing 'tt' is 'PRETTY'.
Can you help me to learn more?
(Other definitions for pretty that I've seen before include "like a kettle of fish" , "Pleasing to look at" , "Nice to look at" , "Pleasing on the eye" , "Attractive in delicate way" .)
