After fine, daughter leaves city — does a runner! (5)
I believe the answer is:
flees
'does a runner' is the definition.
(to do a runner is to flee or run away)
'after fine daughter leaves city' is the wordplay.
'after fine' becomes 'f' (abbreviation. I am not sure about the 'after' bit.).
'daughter' becomes 'd' (genealogical abbreviation).
'leaves' is a deletion indicator.
'city' becomes 'Leeds' (city in England).
'leeds' with 'd' taken away is 'lees'.
'f'+'lees'='FLEES'
Can you help me to learn more?
(Other definitions for flees that I've seen before include "flies" , "Runs away" .)
