Quotation from: The Secret Agent

Written by: Joseph Conrad

He was intensely disgusted in the secrecy of his heart at the unofficial
conduct of his immediate chief. But he was not quixotic. He lost all
desire to await Mr Verloc's return. What they had gone out for he did
not know, but he imagined it possible that they would return together.
The case is not followed properly, it's being tampered with, he thought
bitterly.
