" Karras sat alone and sipped bleakly at his coffee. He felt warm in the sweater that he wore beneath his cassock; felt weak in his failure to have given Chris comfort. Then a memory of childhood shimmered up sadly, a memory of Ginger, his mongrel dog, growing skeletal and dazed in a box in the apartment; Ginger shivering with fever and vomiting while Karras covered her with towels, tried to make her drink warm milk, until a neighbor came by and saw it was distemper, shook his head and said, "Your dog needed shots right away." Then dismissed from school one after-noon... to the street... in columns of twos to the corner... his mother there to meet him... unexpected... looking sad... and then taking his hand to press a shiny half-dollar piece into it... elation... so much money!... then her voice, soft and tender, "Gingie die...." He looked down at the steaming, bitter blackness in his cup and felt his hands empty of comfort or of cure. "
