Steamy row disturbed boy in book (3,6)
I believe the answer is:
tom sawyer
'boy in book' is the definition.
'tom sawyer' can be an answer for 'boy' (I have seen 'American boy' mean 'tom sawyer' so perhaps 'boy' could also mean 'tom sawyer'). I am not sure about the 'in book' bit.
'steamy row disturbed' is the wordplay.
'disturbed' indicates an anagram (the order of letters is disturbed).
'steamy'+'row'='steamyrow'
'steamyrow' anagrammed gives 'TOM SAWYER'.
Can you help me to learn more?
(Other definitions for tom sawyer that I've seen before include "Work" , "a resident of St Petersburg" , "Mark Twain's hero" , "Mark Twain's adventurous boy" , "Mark Twain character" .)
