Welcome return for a girl (3)
I believe the answer is:
eva
'girl' is the definition.
(girl's name)
'welcome return' is the wordplay.
'welcome' becomes 'ave' (I've seen this before).
'return' shows that the letters should be reversed in order.
'ave' in reverse letter order is 'EVA'.
'for a' is the link.
(Other definitions for eva that I've seen before include "Little --, US pop singer" , "Maria -- Duarte De Peron" , "- Braun, Hitler's mistress" , "Dame - - Turner, soprano" , "Miss Peron, perhaps" .)
