The History of Henry Esmond by William Makepeace Thackeray

"Does my mistress know of this? " Esmond asked of Frank, as they walked along.

"My mother found the letter in the book, on the toilet-table. She had writ it ere she had left home," Frank said. "Mother met her on the stairs, with her hand upon the door, trying to enter, and never left her after that till she went away. He did not think of looking at it there, nor had Martin the chance of telling him. I believe the poor devil meant no harm, though I half killed him; he thought 'twas to Beatrix's brother he was bringing the letter."
