Leia's twin (4)
I believe the answer is:
luke
'leia's twin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for luke that I've seen before include "Matthew, Mark, - - and John" , "One of the four Evangelists" , "One of the Gospels" , "One of the Apostles" , "Third NT book" .)
