Work of editor extremely desirable (2,3,3)
I believe the answer is:
to die for
'extremely desirable' is the definition.
(something to die for is extremely desirable)
'work of editor' is the wordplay.
'work' is an anagram indicator.
'of'+'editor'='ofeditor'
'ofeditor' anagrammed gives 'TO DIE FOR'.
(Other definitions for to die for that I've seen before include "hot" , "Extremely desirable (colloq.)" , "Highly desirable or alluring" , "Superb" .)
