from Evelina, volume I, letter XXXIII (Frances Burney)

When we had been out near two hours, and expected every moment to stop at the place of our destination, I observed that Lady Howard’s servant, who attended us on horseback, rode on forward till he was out of sight: and soon after returning, came up to the chariot window, and delivering a note to Madame Duval, said he had met a boy who was just coming with it to Howard Grove from the clerk of Mr. Tyrell.

While she was reading it, he rode round to the other window, and making a sign for secrecy, put into my hand a slip of paper, on which was written, “Whatever happens, be not alarmed - for you are safe - though you endanger all mankind!”

I readily imagined that Sir Clement must be the author of this note, which prepared me to expect some disagreeable adventure: but I had no time to ponder upon it; for Madame Duval had no sooner read her own letter, than, in an angry tone of voice, she exclaimed, “Why, now, what a thing is this! here we’re come all this way for nothing!”
