““The killer simply picked any one of the men in gray suits and followed them from office building to cash machine, from lunchtime restaurant back to office building. Those gray suits were not happy, yet showed their unhappiness only during moments of weakness. Punching the buttons of a cash machine that refused to work. Yelling at a taxi that had come too close. Insulting the homeless people who begged for spare change. But the killer also saw the more subtle signs of unhappiness. A slight limp in uncomfortable shoes. Eyes closed, head thrown back while waiting for the traffic signal. The slight hesitation before opening a door. The men in gray suits wanted to escape, but their hatred and anger trapped them.””
