He takes a return from Hammersmith (3)
I believe the answer is:
tim
'he' is the definition.
(short for Timothy)
'a return from hammersmith' is the wordplay.
'a return' shows that the letters should be reversed in order.
'from' indicates a hidden word.
'mit' is hidden within 'hammersmith'.
'mit' reversed gives 'TIM'.
'takes' is the link.
(Other definitions for tim that I've seen before include "- Rice, musical lyricist" , "Tiny . . . is a loveable Dickens boy" , "Tiny ..., endearing Dickens boy" , "-- Brooke-Taylor, comic" , "Tiny -, Dickens character (A_Christmas Carol)" .)
