Works in Dartmouth (3)
I believe the answer is:
art
'works' is the definition.
(I've seen this before)
'in dartmouth' is the wordplay.
'in' says the answer is hidden in the clue.
'ART' is hidden in the letters of 'dartmouth'.
(Other definitions for art that I've seen before include "The works of Alma-Tadema" , "Works in a gallery" , "Skill, knack" , "Creative works; skill" , "Works of beauty created by humans" .)
