“Neither,” Wolfe lied. “It was ‘a tone of some voice.’” He resumed to Pete, “The art of detection has many levels and many faces. Take one. Shadowing a man around New York without losing him is an extremely difficult task. When the police undertake it seriously they use three men, and even so they are often hoodwinked. There is a man who often works for me, Saul Panzer, who is a genius at it, working alone. I have discussed it with him and have concluded that he himself does not know the secret of his superlative knack. It is not a conscious and controlled operation of his brain, though he has a good one; it is something hidden somewhere in his nervous system-possibly, of course, in his skull. He says that he seems somehow to know, barely in the nick of time, what the man he is following is about to do-not what he has done or is doing, but what he intends. That’s why Mr. Panzer might teach you everything he knows, and still you would never be his equal. But that doesn’t mean you shouldn’t learn all you can. Learning will never hurt you. Only the man who knows too little knows too much. It is only when you undertake to use what you have learned that you discover whether you can transform knowledge into performance.”
Wolfe aimed a thumb at me. “Take Mr. Goodwin. It would be difficult for me to function effectively without him. He is irreplaceable. Yet his actions are largely governed by impulse and caprice, and that would of course incapacitate him for any important task if it were not that he has somewhere concealed in him-possibly in his brain, though I doubt it-a powerful and subtle governor. For instance, the sight of a pretty girl provokes in him an overwhelming reaction of appreciation and approval, and correlatively his acquisitive instinct, but he has never married. Why not? Because he knows that if he had a wife his reaction to pretty girls, now pure and frank and free, would not only be intolerably adulterated but would also be under surveillance and subject to restriction by authority. So the governor always stops him short of disaster, doubtless occasionally on the very brink. It works similarly with the majority of his impulses and whims, but now and then it fails to intervene in time, and he suffers mishap, as this evening when he was impelled to badger me when a certain opportunity offered. It has already cost him-what time is it, Archie?”
I looked. “Eighteen minutes to nine.”
