Drunk must conceal wine, which is novel (5,4,5)
I believe the answer is:
uncle toms cabin
'novel' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I can't see?
'drunk must conceal wine' is the wordplay.
'drunk' is an anagram indicator.
'wine' becomes 'bin' (a bin is a type of container for wine).
'must'+'conceal'='mustconceal'
'mustconceal' is an anagram of 'uncletomsca'.
'uncletomsca'+'bin'='UNCLE TOMS CABIN'
'which is' is the link.
Can you help me to learn more?
(Other definitions for uncle toms cabin that I've seen before include "Harriet's book" , "Volume" , "Anti-slavery novel" , "Harriet Beecher Stowe novel" .)
