Literary no-show (5)
I believe the answer is:
godot
'literary no-show' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for godot that I've seen before include "One awaited by Vladimir and Estragon" , "Two tramps awaited him (Beckett)" , "Samuel Beckett play ''Waiting for . . . . . '' (5)" , "One theatrically waited for" , "someone waited for in theatre" .)
