Figure in a mysterious case on the Continent (6)
I believe the answer is:
alsace
'the continent' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'figure in a mysterious case' is the wordplay.
'figure' becomes 'l' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'mysterious' indicates anagramming the letters.
'case' with letters rearranged gives '[case]'.
'a'+'[case]'='a[case]'
'l' going into 'asace' is 'ALSACE'.
'on' is the link.
Can you help me to learn more?
(Other definitions for alsace that I've seen before include "French region; white wine" , "area of France" , "part of France" , "White wine; Fr. region" , "French region bordering Germany and Switzerland" .)
