Hello, Elle!
"Quotation" is the answer.
Perhaps you are thinking too deeply about St Paul.
St Paul is in the Bible, and could the the setter be misdirecting you to a passage from St Paul, Minnesota?
I'll have a look on YouTube.... but Mark Goodliffe, "the man", won the GB Sudoku Championship at the weekend, to go with his umpteen Times Crossword Championships.
Now, the circus family was/is The Wallendas.
I found them on YouTube and came across of the founder of the troupe, Karl Wallenda, plunging to his death from a high wire in Puerto Rico.
Right, I shall have a look to see if Mark is on YouTube tonight!
