Grave; frantic (9)
I believe the answer is:
desperate
I believe this is a double definition.
'grave' is the first definition.
(thesaurus)
'frantic' is the second definition.
(I've seen this in another clue)
(Other definitions for desperate that I've seen before include "Adept seer (anag)" , "Eater sped to beyond hope" , "critical" , "Feeling hopeless" , "Without hope" .)
