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.

He flexed his toes and ran some muscle tension up through his calves, his thighs, his back, his shoulders. Moved his head side to side and then back a little, to loosen his neck. He breathed in through his nose. The wind was on his back. The guy on the left took his hands out of his pockets. No gloves. And either he had bad arthritis or he was holding rolls of quarters in both palms.

The protection he relied on for nearly thirty years was based on just two things. The same two things anybody uses to protect against any danger. The same way a nation protects itself against an enemy missile, the same way an apartment dweller protects himself against a burglar, the same way a boxer guards against a knockout blow. Detection and response. Stage one, stage two. First you spot the threat coming in, and then you react to it.
