Come back for good time - he finally called (9)
I believe the answer is:
boomerang
'come back' is the definition.
(boomeranging is a kind of coming back)
'good time he finally called' is the wordplay.
'good time' becomes 'boom' (I've seen this in another clue).
'finally' says to take the final letters.
'called' becomes 'rang' (called on the phone).
The last letter of 'he' is 'e'.
'boom'+'e'+'rang'='BOOMERANG'
'for' acts as a link.
(Other definitions for boomerang that I've seen before include "Primitive weapon" , "Australian throwing stick" , "Aboriginal throwing stick" , "Self-returning missile" , "Backfire" .)
