His comeback features in Greene's biography (5)
I believe the answer is:
ibsen
'his' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'comeback features in greene's biography' is the wordplay.
'comeback' says the letters should be written backwards.
'features in' indicates a hidden word (I've seen 'featured in' mean this).
'nesbi' is hidden in the letters of 'greenes biography'.
'nesbi' reversed gives 'IBSEN'.
Can you help me to learn more?
(Other definitions for ibsen that I've seen before include "Henrik -, dramatist from fourteen down (Hedda Gabler)" , "Scandinavian playwright" , "'Ghosts' writer" , "Norwegian author of 'Peer Gynt' etc" , "Is Ben a playwright?" .)
