The prologue opens with a mystery person's point of view on knowledge, power and killing, "People say that knowledge is power. The more knowledge, the more power. Suppose you knew the winning numbers for the lottery? You would run to the store. And you would win. Same for the stock market. You're not talking about a trend or a percentage game or a whisper or a tip. You're talking about knowledge. Real, hard knowledge. You would buy. Then later you'd sell, and you'd be rich. Any kind of sports at all, if you could predict the future, you'd be home and dry. Same for anything. Same for killing people."
