Why is there an allusion to that cursed ’poor knight’ in the anonymous letter?
Why did you write anonymously to worry so noble and generous a lady?
Who was the anonymous person, eh?
"How dared they, how DARED they write that hateful anonymous letter informing me that Aglaya is in communication with Nastasia Philipovna?" she thought, as she dragged the prince along towards her own house, and again when she sat him down at the round table where the family was already assembled.
But he won’t write anonymous letters to the old lady; that would be too audacious a thing for him to attempt; but I dare swear the very first thing he did was to show me up to Aglaya as a base deceiver and intriguer.
"I confess I thought of doing you the service of handing the letter over to yourself, but I decided that it would pay me better to deliver it up to the noble lady aforesaid, as I had informed her of everything hitherto by anonymous letters; so when I sent her up a note from myself, with the letter, you know, in order to fix a meeting for eight o’clock this morning, I signed it ’your secret correspondent.’
There are no more uses of "anonymous" in the book.
