Colonel turns up with friend nearby (7)
I believe the answer is:
locally
'nearby' is the definition.
(I've seen this before)
'colonel turns up with friend' is the wordplay.
'colonel' becomes 'col'.
'turns up' says the letters should be written backwards.
'with' says to put letters next to each other.
'friend' becomes 'ally' (I've seen this before).
'col' backwards is 'loc'.
'loc'+'ally'='LOCALLY'
(Other definitions for locally that I've seen before include "Within a particular area" , "Nearby" , "Happening in neighbouring district" , "In the immediate neighbourhood" , "In the surrounding area" .)
