"Poor child!--poor child!" said he, looking fondly at her, as she lay with her face to the wall, shaking with her sobs. After a while they ceased, and she began to wonder whether she durst give herself the relief of telling her father of all her trouble. But there were more reasons against it than for it. The only one for it was the relief to herself; and against it was the thought that it would add materially to her father's nervousness, if it were indeed necessary for Frederick to come to England again; that he would dwell on the circumstance of his son's having caused the death of a man, however unwittingly and unwillingly; that this knowledge would perpetually recur to trouble him, in various shapes of exaggeration and distortion from the simple truth. And about her own great fault--he would be distressed beyond measure at her want of courage and faith, yet perpetually troubled to make excuses for her. Formerly Margaret would have come to him as priest as well as father, to tell him of her temptation and her sin; but latterly they had not spoken much on such subjects; and she knew not how, in his change of opinions, he would reply if the depth of her soul called unto his. No; she would keep her secret, and bear the burden alone. Alone she would go before God, and cry for His absolution. Alone she would endure her disgraced position in the opinion of Mr. Thornton. 
'Poor child! - poor child!' said he fondly, as she lay with her face to the wall, shaking with sobs. After a while they ceased, and she began to wonder whether she dared tell her father of her trouble. But there were more reasons against it than for it. The only reason for it was the relief to herself; and against it was the thought that it would add greatly to her father's nervousness. He would be troubled by his son's having caused the death of a man, however unwittingly; and he would be distressed beyond measure at her own great fault - her lack of courage and faith - yet would feel the need to make excuses for her.
No; she would keep her secret, and bear the burden alone. Alone she would ask for God's absolution. Alone she would endure her disgrace in Mr. Thornton's opinion.
