Book reader insults a novel (8,6)
I believe the answer is:
treasure island
'book' is the definition.
(I've seen this before)
'reader insults a novel' is the wordplay.
'novel' indicates anagramming the letters.
'reader'+'insults'+'a'='readerinsultsa'
'readerinsultsa' with letters rearranged gives 'TREASURE ISLAND'.
(Other definitions for treasure island that I've seen before include "Book by Stevenson" , "R.L. Stevenson novel" , "work" , "book - with 5a" , "Tale of adventure" .)
