World's End by Richard Jefferies

When Lady Lechester returned from her drive and learnt with intense surprise that Violet was gone, her first thought was that she had been hurt by the remarks made upon Aymer's hallucination the previous evening. Agnes reproached herself for her momentary irritation; but when she found a note for her from Violet on her dressing-table, and had read both it and the enclosed letter from Aymer, her anger was thoroughly aroused.

Not unnaturally she took it in the worst sense, and looked upon it as a downright insult. To pretend that a gentlemen of Marese's position and character was not the heir that he affirmed himself to be -- that he had wooed her under false pretences -- that was bad taste enough, and utterly unjustifiable. Still, it might have passed as the hallucination of an over-tasked mind. But to deliberately accuse the same gentleman of the blackest crime it was possible for human beings to commit, was inexcusable.
