No,' she said. 'No, I don't reckon that's what I do now. Are you watchin', Mrs Gogol? Are you watchin' real close?' Her gaze travelled the room and rested for just a fraction of a second on Magrat. Then she reached over, carefully, and thrust her arm up to the elbow into the burning torch. And the doll in Erzulie Gogol's hands burst into flame. It went on blazing even after the witch had screamed and dropped it on to the floor. It went on burning until Nanny Ogg ambled over with a jug of fruit juice from the buffet, whistling between her teeth, and put it out. Granny withdrew her hand. It was unscathed.
