Author Elmore (7)
I believe the answer is:
leonard
'author elmore' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for leonard that I've seen before include "Elmore ___ , US thriller writer, d. 2013" , "Fellow" , "-- Bernstein, US conductor" , "-- Cohen, singer" , "man" .)
