Dr. Green paced about in his private clinic, sullenly looking over the floor, the light red medicine stains catching his eye. He went to the window and pulled the dark green curtains closed. As he did so, he caught a glimpse of Gelb the butcher crossing the plaza and heading towards him and this apartment he rented. Intuitively, Green knew that Gelb was coming to him as a patient. And sure enough, not five minutes later, the clinic doorbell rang. Green shook off his mood, put on a slight smile, and opened the door.
