"When the day finally comes that I tie Wolfe to a stake and shoot him, one of the fundamental reasons will be his theory that the less I know the more I can help, or to put it another way, that everything inside my head shows on my face. It only makes it worse that he doesn't really believe it. He merely can't stand it to have anybody keep up with him at any time on any track."
