Tim returns, quiet about the forger (5)
I believe the answer is:
smith
'forger' is the definition.
(I've seen this before)
'tim returns quiet about' is the wordplay.
'returns' is a reversal indicator.
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'about' indicates putting letters inside.
'tim' backwards is 'mit'.
'mit' inserted into 'sh' is 'SMITH'.
'the' is the link.
(Other definitions for smith that I've seen before include "Metal-worker" , "Metal worker" , "Person who makes things in metal, may be black" , "Forger" , "Common family name" .)
