Novel a Moravian nun originally absorbed happily at sea? (3,3,2,6)
I believe the answer is:
our man in havana
'novel' is the definition.
(novel by Graham Greene)
'a moravian nun originally absorbed happily at sea?' is the wordplay.
'originally' indicates taking the first letters.
'at sea?' is an anagram indicator (I've seen 'at sea' mean this).
The first letters of 'absorbed happily' is 'ah'.
'a'+'moravian'+'nun'+'ah'='amoraviannunah'
'amoraviannunah' anagrammed gives 'OUR MAN IN HAVANA'.
(Other definitions for our man in havana that I've seen before include "Book" , "work" , "Graham Greene novel" .)
