Lane of The Daily Planet (4)
I believe the answer is:
lois
'lane of the daily planet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lois that I've seen before include "Superman's girlfriend" , "- Lane, girlfriend of Superman" , "- Lane, Daily Planet reporter" , "-- Lane, 'Superman' character" , "Woman" .)
