Calcifer’s voice came into Sophie’s mind, saying, “The contract isn’t doing either of us any good in the long run.” She felt a little chilly, in spite of the heat of the day blowing through the open windows of the shaded, elegant room. “Yes,” she said. “He’s made some sort of contract with his fire demon.”

Mrs. Pentstemmon’s hands shook a little on her stick. “That will be it. You must break that contract, Mrs. Pendragon.”

“I would if I knew how,” Sophie said.

“Surely your maternal feelings and your own strong magic gift will tell you how,” Mrs. Pentstemmon said. “I have been looking at you, Mrs. Pendragon, though you may not have noticed—”

“Oh, I noticed, Mrs. Pentstemmon,” Sophie said.

“—and I like your gift,” said Mrs. Pentstemmon. “It brings life to things, such as that stick in your hand, which you have evidently talked to, to the extent that it has become what the layman would call a magic wand. I think you would not find it too hard to break that contract.”

“Yes, but I need to know what the terms of it are,” Sophie said. “Did Howl tell you I was a witch, because if he did—”

“He did not. There is no need to be coy. You can rely on my experience to know these things,” said Mrs. Pentstemmon. Then, to Sophie’s relief, she shut her eyes. It was like a strong light being turned off. “I do not know, nor do I wish to know, about such contracts,” she said. Her cane wobbled again, as if she might be shuddering. Her mouth quirked into a line, suggesting she had unexpectedly bitten on a peppercorn. “But I now see,” she said, “what has happened to the Witch. She made a contract with a fire demon and, over the years, that demon has taken control of her. Demons do not understand good and evil. But they can be bribed into a contract, provided the human offers them something valuable, something only humans have. This prolongs the life of both human and demon, and the human gets the demon’s magic power to add to his or her own.” Mrs. Pentstemmon opened her eyes again. “That is all I can bear to say on the subject,” she said, “except to advise you to find out what that demon got. Now I must bid you farewell. I have to rest awhile.”

And like magic, which it probably was, the door opened and the page boy came in to usher Sophie out of the room. Sophie was extremely glad to go. She was all but squirming with embarrassment by then. She looked back at Mrs. Pentstemmon’s rigid, upright form as the door closed and wondered if Mrs. Pentstemmon would have made her feel this bad if she had really and truly been Howl’s old mother. Sophie rather thought she would. “I take my hat off to Howl for standing her as a teacher for more than a day!” she murmured to herself.
