Editor takes turn at back door work, by the Dickens! (5,5)
I believe the answer is:
edwin drood
'work by the dickens' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'editor takes turn at back door' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'takes turn' becomes 'wind' (I am not sure about this - if you are sure you should believe this answer much more).
'at' is a charade indicator (letters next to each other).
'back' says the letters should be written in reverse.
'door' in reverse letter order is 'rood'.
'ed'+'wind'+'rood'='EDWIN DROOD'
Can you help me to learn more?
(Other definitions for edwin drood that I've seen before include "The Mystery of -- -- (Dickens; unfinished)" , "Dickens's unfinished mystery tale" , "novel not finished" , "man of mystery" , "7 27 [CHARLES DICKENS] hero" .)
