Sorry, cockie, I meant 24a. Yes, I see now the entry for quote includes 'examine, scrutinize.'
A further bit of information that might be useful is in the hidden message. Assuming 'clues' really means entries, there are ten known entries that may contain one of the highlighted letters to give the thematic title; hopefully all of them do. One of them is only four letters long. It might help to narrow down the search.
