We did not live in London then; papa went up and down every day from the big town by the sea where our home was. Clement thinks perhaps I had better not say what town it is, as some people might remember about us, and I might say things that would vex them; so I won't call it anything, though I must explain that it is not at all a little place, but quite big enough for any one to lose their way in, if they were strangers. But Peterkin wasn't a stranger; and the way he had to come was, as nurse said, as straight as straight.

We all listened with grave faces to what nurse told us. Suddenly Clement got up—I can't say 'jumped up,' for he was always rather slow.

'Nurse,' he said, 'mamma's out, so I can't ask her leave. But I've got an idea about Peterkin. Will you give me leave to go out for half-an-hour or so? I promise you I won't go far, but I would rather not tell you where I want to go, as it may be all nonsense.'

Nurse looked at him doubtfully. She trusted Clem the most of us all, I know, and she had good reason to do so, for he was and is very trustworthy. And it was nice of him to ask her leave, considering he was twelve years old and quite out of the nursery, except that he still liked having tea there when he came in from school every evening.

'Well, Master Clement,' said nurse, 'I don't quite know. Supposing you go out and don't get back as soon as you expect? It would be just a double fright for your poor mamma.'

'Let me go too!' I exclaimed, and I jumped up so suddenly that I made all the cups rattle and nearly threw over the table altogether. 'Then if anything stops Clem getting back quickly, I can run home and explain. Anyway you'd be more comfortable if you knew the two of us were on the hunt together. You don't mind my coming, do you, Clem?'

'No,' said Clem, 'but do let's go.'

'And you won't be long?' pleaded nurse.

Clem shook his head.

'I don't think we can be—not if there's anything in my idea', he called out, as we ran off.
