“Yes.” Bill was distinctly short about it.

“How?”

“What?”

“I said, ‘How?’ ”

“How? How do ghosts appear? I don’t know. They just appear.”

“Over four or five hundred yards of open park?”

“Well, but she had to appear here, because this is where the original one⁠—Lady Anne, you know⁠—was supposed to walk.”
