The_Complete_Chronicles_of_Narnia_(volumes_1-7,_in_order_of_publication)

"Miss Ketterley, this is the most extraordinary case I have known in my whole medical
career. It is - it is like a miracle. I wouldn't tell the little boy anything at present; we don't
want to raise any false hopes. But in my opinion -" then his voice became too low to hear.
That afternoon he went down the garden and whistled their agreed secret signal for Polly
(she hadn't been able to get back the day before).
"What luck?" said Polly, looking over the wall. "I mean, about your Mother?"
"I think - I think it is going to be alright," said Digory. "But if you don't mind I'd really
rather not talk about it yet. What about the rings?"
"I've got them all," said Polly. "Look, it's alright, I'm wearing gloves. Let's bury them."
"Yes, let's. I've marked the place where I buried the core of the Apple yesterday."
Then Polly came over the wall and they went together to the place. But, as it turned out,
Digory need not have marked the place. Something was already coming up. It was not
growing so that you could see it grow as the new trees had done in Narnia; but it was
already well above ground. They got a trowel and buried all the magic rings, including
their own ones, in a circle round it.
About a week after this it was quite certain that Digory's Mother was getting better.
About a fortnight later she was able to sit out in the garden. And a month later that whole
house had become a different place. Aunt Letty did everything that Mother liked;
windows were opened, frowsy curtains were drawn back to brighten up the rooms, there
were new flowers everywhere, and nicer things to eat, and the old piano was tuned and
Mother took up her singing again, and had such games with Digory and Polly that Aunt
Letty would say "I declare, Mabel, you're the biggest baby of the three."
When things go wrong, you'll find they usually go on getting worse for some time; but
when things once start going right they often go on getting better and better. After about
six weeks of this lovely life there came a long letter from Father in India, which had
wonderful news in it. Old Great-Uncle Kirke had died and this meant, apparently, that
Father was now very rich. He was going to retire and come home from India forever and
ever. And the great big house in the country, which Digory had heard of all his life and
never seen would now be their home; the big house with the suits of armour, the stables,
the kennels, the river, the park, the hot-houses, the vineries, the woods, and the mountains
behind it. So that Digory felt just as sure as you that they were all going to live happily
ever after. But perhaps you would like to know just one or two things more.
Polly and Digory were always great friends and she came nearly every holidays to stay
with them at their beautiful house in the country; and that was where she learned to ride
and swim and milk and bake and climb.
