drama

I'm a little stuck... Click here to teach me more about this clue!

'play?' is the definition.
(I know that play can be written as drama)

'result of doctoring a master' is the wordplay.
'result' becomes 'dra' (I can't explain this - if you can you should believe this answer much more).
'of doctoring' indicates anagramming the letters (I've seen 'doctors' mean this).
'master' becomes 'M' (common abbreviation eg MA, Master of Art).
'a'+'m'='am'
'am' is an anagram of 'ma'.
'dra'+'ma'='DRAMA'
