Towers may be recreated in book (3,6)
I believe the answer is:
tom sawyer
'book' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'towers may be recreated' is the wordplay.
'be recreated' indicates an anagram.
'towers'+'may'='towersmay'
'towersmay' anagrammed gives 'TOM SAWYER'.
'in' is the link.
Can you help me to learn more?
(Other definitions for tom sawyer that I've seen before include "American boy" , "Mark Twain character" , "Boy hero of Mark Twain novel" , "Mark Twain's adventurous boy" , "a resident of St Petersburg" .)
