People say that knowledge is power. The more knowledge, the more power. Suppose you knew the winning numbers for the lottery? All of them? Not guesse… - Lee Child

Seven thirty-nine, more than three hundred miles to the north and east, Jack Reacher climbed out of his motel room window. One minute earlier, he had been in the bathroom, brushing his teeth. One minute before that, he had opened the door of his room to check the morning temperature. He had left it open, and the closet just inside the entrance passageway was faced with mirrored glass, and there was a shaving mirror in the bathroom on a cantilevered arm, and by a freak of optical chance he caught sight of four men getting out of a car and walking toward the motel office. Pure luck, but a guy as vigilant as Jack Reacher gets lucky more times than the average.

As serious as a heart attack. Maybe those were Ken Kramer's last words, like a final explosion of panic in his mind as he stopped breathing and dropped into the abyss. He was out of line, in every way there was, and he knew it. He was where he shouldn't have been, with someone he shouldn't have been with, carrying something he should have kept in a safer place. But he was getting away with it. He was playing and winning. He was on top of his game. He was probably smiling. Until the sudden thump deep inside his chest betrayed him. Then everything turned around. Success became instant catastrophe. He had no time to put anything right.

Suppose you wanted to kill people. You would need to know ahead of time how to do it. That part is not too difficult. There are many ways. Some of them are better than others. Most of them have drawbacks. So you use what knowledge you've got, and you invent a new way. You think, and you think, and you think, and you come up with the perfect method. You pay a lot of attention to the setup. Because the perfect method is not an easy method, and careful preparation is very important. But that stuff is meat and potatoes to you. You have no problem with careful preparation. No problem at all. How could you, with your intelligence? After all your training? You know the big problems will come afterward. How do you make sure you get away with it? You use your knowledge. You know more than most people about how the cops work. You've seen them on duty many times, sometimes close-up. You know what they look for. So you don't leave anything for them to find. You go through it all in your head, very precisely and very exactly and very carefully. Just as carefully as you would mark the play card you knew for sure was going to win you a fortune.
