There is a saying, “You can’t fool an honest man,” which is much quoted by people who make a profitable living by fooling honest men. Moist never tried it, knowingly anyway. If you did fool an honest man, he tended to complain to the local Watch, and these days they were harder to buy off. Fooling dishonest men was a lot safer and, somehow, more sporting. And, of course, there were so many more of them. You hardly had to aim.
