Some schemer gets to break cover (6)
I believe the answer is:
emerge
'break cover' is the definition.
(thesaurus)
'some schemer gets to' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'EMERGE' can be found hidden inside 'schemer gets to'.
(Other definitions for emerge that I've seen before include "Rise to notice" , "Suddenly appear" , "Move out and become visible" , "Gradually come out" , "Break out (from an egg)" .)
