Joseph Conrad,
Nostromo: A Tale of the Seaboard
“ Mrs Gould watched his abstraction with dread. It was a domestic and frightful phenomenon that darkened and chilled the house for her like a thundercloud passing over the sun. Charles Gould’s fits of abstraction depicted the energetic concentration of a will haunted by a fixed idea. A man haunted by a fixed idea is insane. He is dangerous even if that idea is an idea of justice; for may he not bring the heaven down pitilessly upon a loved head? The eyes of Mrs. Gould, watching her husband’s profile, filled with tears again. And again she seemed to see the despair of the unfortunate Antonia. ”
