A nightmare?

By now, I am halfway 'The man who was Thursday', and I am enjoying it completely. The combination of discussions about anarchism and the plot in which Syme actually becomes member of an underground organization is fast paced, hilarious, and deep at the same time.

"The work of the philosophical policeman is at once bolder and more subtle than that of the ordinary detective. The ordinary detective goes to pot-houses to arrest thieves; we go to artistic tea-parties to detect pessimists. The ordinary detective discovers from a ledger or a diary that a crime has been committed. We discover from a book of sonnets that a crime will be committed. We have to trace the origin of those dreadful thoughts that drive men on at last to intellectual fanaticism and intellectual crime."
