Issues comprising treason, start to finish (8)
I believe the answer is:
editions
'issues' is the definition.
(edition is a kind of issue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for editions that I've seen before include "Numbers" , "Book published at different times" , "issues for the press" , "Copies of book about sedition" , "written publications?" .)
