"Prevention of crime is not what policemen are best at. They would need to have one constable for each citizen and go everywhere with him. But fortunately for the human race, most of us have our own little policeman [points to forehead] up here. This kidnapper has, perhaps, no little policeman." -- Hercule Poirot, in "The Adventure of Johnnie Waverly", by Agatha Christie (b. 1890-09-15, d. 1976-01-12)
