'Oh!' she exclaimed, with a little scream, 'is it _that_ you are afraid of, Giles? Do you think we are in the _London_ train? I did think it was funny that we were getting back into the same one, but you said that the man said that the carriages at the front were for Hill Horton?'

'Well, I _thought_ he did,' I replied, 'but--' one's mind works quickly when you are frightened sometimes--'he _might_ have said "Victoria," for the "tor" in "Victoria" and "Horton" sound rather alike.'

'But wouldn't he have said "London"?' asked Peterkin.

'No, I think they generally say the name of the station in London,' I explained. 'There are so many, you see.'

Then we all, for a minute or two, gazed at each other without speaking.

Margaret had got still paler than usual, and I fancied, or feared, I heard her choke down something in her throat. Peterkin, on the contrary, was as red as a turkey-c.o.c.k, and his eyes were gleaming. I think it was all a part of the fairy-tale to him.

'What shall we do?' said Margaret, at last, and I was forced to answer, 'I don't know.'

Bit by bit things began to take shape in my mind, and it was no good keeping them to myself.

'There'll be the extra money to pay for our tickets to London,' I said at last.

'How much will it be? Isn't there enough over?' asked Margaret quietly, and I could not help admiring her for it, as she took out her purse and gave it to me to count over what was left.

There were only four or five shillings. I shook my head.

'I don't know how much it will be, but I'm quite sure there's not enough. You see, though we're only halves, it's first-cla.s.s.'

'And what will they do to us if we can't pay,' she went on, growing still whiter. 'Could we--could we possibly be sent to prison?'

'Oh no, no. I don't think so,' I answered, though I was really not at all sure about it; I had so often seen notices stuck up on boards at railway stations about the punishments of pa.s.sengers not paying properly, or trying to travel without tickets. 'But--I'm afraid they would be very horrid to us somehow--perhaps telegraph to papa or mamma.'

'Oh!' cried Margaret, growing now as red as she had been white, 'and that would mean my being shut up again at Rock Terrace--worse than before. I don't know _what_ the witch wouldn't do to me,' and she clasped her poor little hands in a sort of despair.

Then Peterkin burst out--

'I've got my gold half-pound with me,' he said, in rather a queer voice, as if he was proud of being able to help and yet half inclined to cry.

'Goodness!' I exclaimed, 'why on earth didn't you say so before?'

'I--I--wanted it for something else,' said he. 'I don't quite know why I brought it.'

He dived into his pocket, and dug out a very grimy little purse, out of which, sure enough, he produced a half-sovereign.

The relief of knowing that we should not get into trouble as far as our journey _to_ London was concerned, was such a blessing, that just for the moment I forgot all the rest of it.

'Anyway we can't be put in prison now,' said Margaret, and a little colour came into her face. 'Oh, Perkins, you _are_ a nice boy!'

I did think her praising him was rather rough on _me_, for I had had bother enough, goodness knows, about the whole affair, even though I had made a stupid mistake.

We whizzed on, for it was an express train, and for a little while we didn't speak. Peterkin was still looking rather upset about his money.

He told me afterwards that he had been keeping it for his Christmas presents, especially one for Margaret, as we had never had a chance of getting her any flowers. But all that was put right in the end.

After a bit Margaret said to me, in a half-frightened voice--

'What shall we do when we get to London, Giles? Do you think perhaps the guard would help us to go back again to the Junction, when he sees it was a mistake? As we've got money to pay to London, he'd see we hadn't meant to cheat.'

'No,' I said, 'he wouldn't have time, and besides I don't think it'll be the same one. And if we said anything, he'd most likely make us give our names, or take us to some station-master or somebody, and then there'd be no chance of our keeping out of a lot of bother.'

'You mean,' said she, in a shaky voice, 'we should have to go all the way back, and I'd be sent to the witch again?'

'Something like it, I'm afraid,' I said. 'If I just explain that we got into the wrong train and pay up, they'll have no business to meddle with us.'

'But what are we to do, then?' she asked again.

'I don't know,' I replied. I'm afraid I was rather cross. I was so sick of it all, you see, and so fearfully bothered.

Margaret at last began to cry. She tried to choke it down, but it was no use.

I felt awfully sorry for her, but somehow the very feeling so bad made me crosser, and I did not try to comfort her up.

Pete, on the contrary, tugged out his pocket-handkerchief, which was quite a decently clean one, and began wiping her eyes. This made her try again to stop crying. She pulled out her own handkerchief and said--

'Dear little Perkins, you are so kind.'

I glanced at them, not very amiably, I daresay. And I was on the point of saying that, instead of crying and petting each other, they'd better try to think what we should do, for I knew we must be getting near London by this time, when I saw something white on the floor of the carriage.

I stooped to pick it up. It had dropped out of Margaret's pocket when she pulled out her handkerchief. It was an envelope, or what had been one, and for a moment I thought it was the one I had given her with our address on, to use when she wrote to us from Hill Horton, but _that_ one couldn't have got so dirty and torn-looking in the time. And when I looked at it more closely, I saw that it was jagged and nibbled in a queer way, and _then_ I saw that it had the name 'Wylie' on it, and an address in London. And when I looked still more closely, I saw that it had never been through the post or had a stamp on, and that it had a large blot in one corner. Evidently the person who had written on it had not liked to use it because of the blot, and the name on it was _Miss_, not _Mrs._ Wylie, '19 Enderby Street LONDON, S.W.'

I turned it round and round without speaking for a moment or two. I couldn't make it out. Then I said--

'What's this, Margaret? It must have dropped out of your pocket.'

She stopped crying--well, really, I think she had stopped already, for whatever her faults were she wasn't a babyish child--to look at it. She seemed puzzled, and felt in her pocket again.

'No, of course it's not the envelope you gave me,' she said. 'I've got it safe, and--oh, I believe I know how this old one got into my pocket.

I remember a day or two ago when I was trying if it would do to tie my handkerchief on to Polly's cage, he was nibbling some paper. He's very fond of nibbling paper, and it doesn't hurt him, for he doesn't eat it.

But he would keep pecking at me when I was tying the handkerchief, and I was vexed with him, and so when he dropped this I picked it up and shook it at him, and told him he shouldn't have it again, and then I put it into my pocket. He was very tiresome that day, not a bit a fairy; he is like that sometimes.'

'But how did he come to have an envelope with "Miss Wylie" on?' I said.

'He doesn't live in Mrs. Wylie's house, but in the one between yours and hers, and this must have come from _her_.'

'I daresay she gave it him to play with, or her servant may have given it him,' said Margaret, 'You see he's sometimes at the end of the balcony nearest her, and sometimes at our end. I think his servants have put him more at our end since she's been away; perhaps they've heard me talking to him. Anyway, I'm sure this old envelope must have come out of his cage.'

I did not speak for a moment. I was gazing at the address.

'Margaret,' I exclaimed, 'look at it.'

She did so, and then stared up at me, with a puzzled expression in her eyes, still red with crying.

'I believe,' I went on, 'I believe this is going to help us.'

Peterkin, who had been listening with all his ears, could contain himself no longer.

'And the parrot _must_ be a fairy after all,' he said, 'and he must have done it on purpose.'
