She takes the ring road, wrongly (8)
I believe the answer is:
Here is my best explanation:
'she' is the definition.
'the ring road wrongly' is the subsidiary indication.
'ring' becomes 'o'.
'wrongly' indicates anagramming the letters.
'road' anagrammed gives 'dora'.
'takes' is the link.
(Other definitions for theodora that I've seen before include "Lady", "gift from God", "Byzantine empress" and "Oratorio by Handel".)
