Fruit from gloomy northern town you might gather (9)
I believe the answer is:
blueberry
'fruit' is the definition.
(blueberry is a kind of fruit)
'gloomy northern town you might gather' is the wordplay.
'gloomy' becomes 'blue' (I've seen this before).
'northern town' becomes 'bury' (I've seen this before).
'you might gather' indicates a 'sounds like' (homophone) clue.
'bury' sounds like 'berry'.
'blue'+'berry'='BLUEBERRY'
'from' is the link.
(Other definitions for blueberry that I've seen before include "Small succulent fruit" , "North American soft fruit" , "North American fruit (with which to make pies)" , "fruit plant" .)
