Works in Dumbarton (3)

I believe the answer is:

art

'works' is the definition.
(I've seen this before)

'in dumbarton' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ART' is hidden within 'dumbarton'.

(Other definitions for art that I've seen before include "Drawing" , "eg Painting" , "Trickery" , "For example, Blakey's creative" , "Skill, knack" .)

I've seen this clue in The Sun.
