'Well?' said Phyllis.

'Yes,' said Mabel; 'what an inciting adventure! What a dear he is! I do hope we shall see his little girl to-morrow.'

'Yes,' said Guy slowly, 'but I don't think we shall.'

'Why ever not?'

'Because I don't believe he's got any little girl. We went into all the rooms, and the hall and landing. There wasn't any other room for the little girl to be in.'

'Perhaps it was really her under the sheet, trying to be ghosts,' said Phyllis.

'It was too high up,' said Mabel.

'She might have been standing on a stool,' said Phyllis.

'Well,' said Guy, with a satisfied look; 'it's a very thrilling mystery.'

It was. And it gave them something to think of for the next few days.

For that evening when they went to fetch the Christmas-tree, they found the door of Sir Christopher's castle tight shut, and their Christmas-tree was standing alone on the doorstep in the dark.

After vainly knocking several times, they put the tree into the wheelbarrow and got it home, only upsetting it three times by the way.

When they got it into the light of their schoolroom they saw that there was a piece of paper on it--a note.

'My dears,' it said, 'here is your beautiful tree. Thank you very much.

If you knew how much pleasure it had given me you would be glad. Why not give the tree to some poor child? Good-bye. G.o.d bless you!'

There were some letters tangled together at the bottom of the page.

'His initials, I suppose,' said Guy. But n.o.body could read them.

'Anyway, it means he doesn't want to see us any more,' said Phyllis.

'Oh, I do wish we knew something more about him.'

But they took his advice, and the tree went to the gardener's little boy, who was ill. It made him almost forget his illness for days and days.

When father came home they asked him who lived in the Grotto. He told them.

'He has lived there for years,' he said. 'I have heard that when he came into his property he found that his property was almost all debts. So he sold the tea-gardens for building on, and has lived there in the Grotto on next to nothing, and all these years he's been paying off his father's creditors. I should think they're about paid off by now.'

'Has he a little girl?' asked Phyllis.

'Yes--I believe so,' said father absently.

'It's very odd,' Mabel was beginning, but the others silenced her.

After this the children were more interested than ever in Sir Christopher. They used to paint illuminated texts, and make picture-frames of paper rosettes, and buy toys, and leave them on his doorstep in the dark, 'For the little girl,' and as the spring came on, bunches of flowers.

It was one evening when Phyllis came to the castle with a big bunch of plumy purple lilac. She was earlier than usual, and it was not quite dark, and--wonder of wonders--the door of the castle was open. Still more wonderful, Sir Christopher stood on the doorstep.

'I was watching for you,' he said. 'I had a sort of feeling you'd come to-night. Will you come in?'

He led her into the black marble room and stood looking wistfully at her.

'Would you like to see my little girl?' he said suddenly.

'Yes,' said Phyllis.

'I didn't think you'd understand,' he said, 'when you came at Christmas.

But you've been so kind and faithful all these months. I think you will understand. Look!'

He pulled the sheet from the statue, and Phyllis looked on the white likeness of a little girl of her own age, dressed in a long gown like a nightgown.

'It is very beautiful,' she said.

'Yes,' he said. 'Have you ever heard any tales about me?' he asked.

'Yes,' said Phyllis, and told him.

'It's not true,' he said. My father had no debts. But I married someone he didn't like; and then I got ill, and couldn't work. My father was very hard. He wouldn't help us. My wife died, and then my father died, and all his great wealth came to me. Too late! too late! The letter that told me I was rich came to me when I was sitting beside my dead child.

The money came _then_--the money that would have saved her. The first money I spent out of it all was spent on that statue. It was done as she lay dead.'

Phyllis looked at the statue, and felt--she didn't know why--very frightened. Then she looked at him, and she was not frightened any more.

She ran to him and put her arms round him.

'Oh, poor, poor, dear Sir Christopher!' she said.

'That's how she looked when she was dead,' he said; 'would you like to see my ladybird as she was when she was alive and well, and I was a strong man able to work for her?'

'Yes--oh yes,' said Phyllis.

He led the way into the pearly room, and drew back a green curtain that hung there. Phyllis caught her breath sharply, and tears p.r.i.c.ked her eyes. Not because the picture was a sad one--ah, no! not that!

As the curtain was withdrawn the figure of a child seemed to spring towards them from the canvas--a happy, laughing child, her arms full of roses, her face full of health and beauty and the joy of life; a child whose glad, unclouded eyes met Phyllis's in a free, joyous look.

'Oh no!' cried Phyllis; 'she can't be dead--she _can't_!'

The old man took her in his arms, for she was crying bitterly.

'Thank you--thank you, dear,' he said, soothing her. 'Now I know that you are the right person to help me.'

'I? Help _you_?'

Phyllis's tears began to dry at the beautiful thought, but she still sobbed.

'Don't cry,' he said, and gently drew the green curtain over the lovely laughing face. 'Don't cry. I want to tell you of many things. When that money came--I've told you when--as soon as I could see or think again, I saw what I ought to do. Ever since I've not spent a penny of that money on myself--on anything but the plainest food, the plainest clothes. If I've made the house beautiful for her picture to live in, it's been with my own work. All the rest of the money has gone to help little girls whose fathers can't work for them--little girls that can be saved, as my little girl could have been saved. That's the work I want you to carry on for me when you grow up. Will you promise?'

'Yes,' said Phyllis; 'only I'm very stupid.'
