____ Skywalker (4)
I believe the answer is:
luke
'skywalker' 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 "Traditionally the author of the third Gospel" , "Biblical evangelist" , "One of the Gospels" , "Matthew, Mark, - - and John" , "One of the four Evangelists" .)
