Controlled some of them from there in Edinburg (6,2)
I believe the answer is:
reined in
'controlled' is the definition.
(reining in is a kind of controlling)
'from there in edinburg' is the wordplay.
'from' indicates a hidden word.
'REINED IN' is hidden in the letters of 'there in edinburg'.
'some of them' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for reined in that I've seen before include "Checked - stopped" , "Curbed" , "'Slowed, checked (6,2)'" , "restricted" , "Stopped or slowed up, a horse perhaps" .)
