"No, I didn't." He nodded to the porch, where a newspaper sat waiting, and began a slow walk over to it. "I got to York on March 27, 2012," he said. He let that sink in.
Then he bent, picked up the newspaper, and checked its date.
With a slightly bemused expression, he turned it so that Harry could read it, too.
