Endlessly devoured strange work (6)
I believe the answer is:
oeuvre
'work' is the definition.
(an oeuvre is someone's collected works)
'endlessly devoured strange' is the wordplay.
'endlessly' says to take the centre (the ends of the words are removed).
'strange' indicates anagramming the letters.
The centre of 'devoured' is 'evoure'.
'evoure' is an anagram of 'OEUVRE'.
(Other definitions for oeuvre that I've seen before include "Collected works" , "Total output of a writer or artist" , "(Artist's) body of work" , "Author's body of work" , "Body of work of an artist (6)" .)
