Briony Reads the Letter

Driven by a 'savage and thoughtless curiosity,' Briony opens the envelope and reads Robbie's obscene letter. The word 'cunt' shocks and disgusts her profoundly. She has never encountered the word before, but she intuitively understands its meaning and feels it as a threat to the order of her household. She immediately casts herself as her sister's protector, believing that Robbie is a 'maniac' who must be exposed. This act of reading a private letter is a violation of trust, but Briony justifies it as necessary for her sister's safety. Her interpretation of the letter is shaped by her earlier misinterpretation of the fountain scene, and it solidifies her conviction that Robbie is a dangerous and evil person.
