Pointer for gold seekers in dodgy bar I own (7)
I believe the answer is:
rainbow
'pointer for gold seekers' is the definition.
(as in a pot of gold at the end of a rainbow)
'dodgy bar i own' is the wordplay.
'dodgy' is an anagram indicator (a dodgy or wrong order of the letters).
'bar'+'i'+'own'='bariown'
'bariown' with letters rearranged gives 'RAINBOW'.
'in' is the link.
(Other definitions for rainbow that I've seen before include "in different colours" , "Arc of colour in the sky" , "Multicoloured atmospheric phenomenon" , "Polychromatic arc" , "Colourful phenomenon" .)
