Woman in overturned vehicle concealing terrible rage (8)
I believe the answer is:
margaret
'woman' is the definition.
'overturned vehicle concealing terrible rage' is the wordplay.
'overturned' says the letters should be written backwards.
'vehicle' becomes 'tram' (tram is a kind of vehicle**).
'concealing' means one lot of letters goes inside another.
'terrible' indicates an anagram.
'tram' back-to-front is 'mart'.
'rage' is an anagram of 'gare'.
'mart' enclosing 'gare' is 'MARGARET'.
'in' is the link.
(Other definitions for margaret that I've seen before include "- of Anjou, consort to Henry VI" , "- Rutherford, actress" , "...Drabble, Princess ..." , "Name of saintly Scottish queen" , "-- Drabble, writer" .)
