Quote from : The Man Who Was Thursday: A Nightmare Book

His soul swayed in a vertigo of moral indecision. He had only to snap the thread of a rash vow made to a villainous society, and all his life could be as open and sunny as the square beneath him. He had, on the other other hand, only to keep his antiquated honour, and be delivered inch by inch into the power of this great enemy of mankind, whose very intellect was a torture-chamber. Whenever he looked down into the square he saw the comfortable policeman, a pillar of common sense and common order. Whenever he looked back at the breakfast-table he saw the President still quietly studying him with big, unbearable eyes.
