The really good hitman does his homework, making a complete study of his victim, his habits, his friends and associates, the places he goes for a drink or to buy his morning paper. He will follow him for days and sometimes weeks, ascertaining what the victim’s routine is, searching out potential locations for the hit, and, of course, ensuring that there is an escape route to get him away from the scene of the killing as swiftly and as calmly as possible.
