Local line running through Rochester (4)
I believe the answer is:
oche
'local line' is the definition.
'oche' can be an answer for 'line' (I've seen this before). I am not sure about the 'local' bit.
'running through rochester' is the wordplay.
'OCHE' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for oche that I've seen before include "Line behind which darts players stand" , "Line of 25 [ARROEWS]" , "Heavy African knife" , "Line from which a dart player throws" , "Dart-throwing line" .)
