Greta says, “They always seemed the books that were most important to me. The ones that mattered. When I was a kid, and when I grew. I was like Dahl’s Matilda… Were your family great readers?”

“Not really… I say that, it was a long time ago that they died. Were killed. I should say.”

“All your family died at the same time? Was this in the war?”

“No, dear. We were evacuees, in the war. This was in a train crash, several years after. I was not there.”

“Just like in Lewis’s Narnia books,” says Greta, and immediately feels like a fool, and an insensitive fool. “I’m sorry. That was a terrible thing to say, wasn’t it?”

“Was it, dear?”

Greta can feel herself blushing, and she says, “It’s just I remember that sequence so vividly. In The Last Battle. Where you learn there was a train crash on the way back to school, and everyone was killed. Except for Susan, of course.”

The professor says, “More tea, dear?” and Greta knows that she should leave the subject, but she says, “You know, that used to make me so angry.”

“What did, dear?”

“Susan. All the other kids go off to Paradise, and Susan can’t go. She’s no longer a friend of Narnia because she’s too fond of lipsticks and nylons and invitations to parties. I even talked to my English teacher about it, about the problem of Susan, when I was twelve.”

She’ll leave the subject now, talk about the role of children’s fiction in creating the belief systems we adopt as adults, but the professor says, “And tell me, dear, what did your teacher say?”

“She said that even though Susan had refused Paradise then, she still had time while she lived to repent.”

“Repent what?”

“Not believing, I suppose. And the sin of Eve.”

The professor cuts herself a slice of chocolate cake. She seems to be remembering. And then she says, “I doubt there was much opportunity for nylons and lipsticks after her family was killed. There certainly wasn’t for me. A little money-less than one might imagine-from her parents’ estate, to lodge and feed her. No luxuries…”

“There must have been something else wrong with Susan,” says the young journalist, “something they didn’t tell us. Otherwise she wouldn’t have been damned like that-denied the Heaven of further up and further in. I mean, all the people she had ever cared for had gone on to their reward, in a world of magic and waterfalls and joy. And she was left behind.”

“I don’t know about the girl in the books,” says the professor, “but remaining behind would also have meant that she was available to identify her brothers’ and her little sister’s bodies. There were a lot of people dead in that crash. I was taken to a nearby school-it was the first day of term, and they had taken the bodies there. My older brother looked okay. Like he was asleep. The other two were a bit messier.”

“I suppose Susan would have seen their bodies, and thought, they’re on holidays now. The perfect school holidays. Romping in meadows with talking animals, world without end.”

“She might have done. I only remember thinking what a great deal of damage a train can do, when it hits another train, to the people who were traveling inside. I suppose you’ve never had to identify a body, dear?”

“No.”

“That’s a blessing. I remember looking at them and thinking, What if I’m wrong, what if it’s not him after all? My younger brother was decapitated, you know. A god who would punish me for liking nylons and parties by making me walk through that school dining room, with the flies, to identify Ed, well…he’s enjoying himself a bit too much, isn’t he? Like a cat, getting the last ounce of enjoyment out of a mouse. Or a gram of enjoyment, I suppose it must be these days. I don’t know, really.”

She trails off. And then, after some time, she says, “I’m sorry dear. I don’t think I can do any more of this today. Perhaps if your editor gives me a ring, we can set a time to finish our conversation.”

Greta nods and says of course, and knows in her heart, with a peculiar finality, that they will talk no more.

That night, the professor climbs the stairs of her house, slowly, painstakingly, floor by floor. She takes sheets and blankets from the airing cupboard, and makes up a bed in the spare bedroom, at the back. It is empty but for a wartime austerity dressing table, with a mirror and drawers, an oak bed, and a dusty applewood wardrobe, which contains only coathangers and a cardboard box. She places a vase on the dressing table, containing purple rhododendron flowers, sticky and vulgar.

She takes from the box in the wardrobe a plastic shopping bag containing four old photographic albums. Then she climbs into the bed that was hers as a child, and lies there between the sheets, looking at the black-and-white photographs, and the sepia photographs, and the handful of unconvincing color photographs. She looks at her brothers, and her sister, and her parents, and she wonders how they could have been that young, how anybody could have been that young.

After a while she notices that there are several children’s books beside the bed, which puzzles her slightly, because she does not believe she keeps books on the bedside table in that room. Nor, she decides, does she usually have a bedside table there. On the top of the pile is an old paperback book-it must be more than forty years old: the price on the cover is in shillings. It shows a lion, and two girls twining a daisy chain into its mane.

The professor’s lips prickle with shock. And only then does she understand that she is dreaming, for she does not keep those books in the house. Beneath the paperback is a hardback, in its jacket, of a book that, in her dream, she has always wanted to read: Mary Poppins Brings in the Dawn, which P. L. Travers had never written while alive.

She picks it up and opens it to the middle, and reads the story waiting for her: Jane and Michael follow Mary Poppins on her day off, to Heaven, and they meet the boy Jesus, who is still slightly scared of Mary Poppins because she was once his nanny, and the Holy Ghost, who complains that he has not been able to get his sheet properly white since Mary Poppins left, and God the Father, who says, “There’s no making her do anything. Not her. She’s Mary Poppins.”

“But you’re God,” said Jane. “You created everybody and everything. They have to do what you say.”

“Not her,” said God the Father once again, and he scratched his golden beard flecked with white. “I didn’t create her. She’s Mary Poppins.”

And the professor stirs in her sleep, and afterward dreams that she is reading her own obituary. It has been a good life, she thinks, as she reads it, discovering her history laid out in black and white. Everyone is there. Even the people she had forgotten.

Greta sleeps beside her boyfriend, in a small flat in Camden, and she, too, is dreaming.

In the dream, the lion and the witch come down the hill together.

She is standing on the battlefield, holding her sister’s hand. She looks up at the golden lion, and the burning amber of his eyes. “He’s not a tame lion, is he?” she whispers to her sister, and they shiver.

The witch looks at them all, then she turns to the lion, and says, coldly, “I am satisfied with the terms of our agreement. You take the girls: for myself, I shall have the boys.”

She understands what must have happened, and she runs, but the beast is upon her before she has covered a dozen paces.

The lion eats all of her except her head, in her dream. He leaves the head, and one of her hands, just as a housecat leaves the parts of a mouse it has no desire for, for later, or as a gift.

She wishes that he had eaten her head, then she would not have had to look. Dead eyelids cannot be closed, and she stares, unflinching, at the twisted thing her brothers have become. The great beast eats her little sister more slowly, and, it seems to her, with more relish and pleasure than it had eaten her; but then, her little sister had always been its favorite.
