Go furtively about forging links (5)

I believe the answer is:

slink

'go furtively' is the definition.
(I've seen this in another clue)

'forging links' is the wordplay.
'forging' indicates an anagram (I've seen this in other clues).
'links' is an anagram of 'SLINK'.

'about' acts as a link.

(Another definition for slink that I've seen is " Hide".)

I've seen this clue in the Evening Standard.
