He climbed to the model's platform and seated himself as upon the previous morning, with a kind of business-like directness. "Ready when you are," he said. Barbara withdrew the damp cloths from the clay, looked critically from the bust to the original and back again. "My work," she said, "still looks right to me. But you don't." Blizzard smiled.
