"Yes, I can hear what you say, but when most people talk I am like a prisoner locked up; and every day there are more and more locked doors between me and the world. You do not know how horrible it is." "Oh, well," said the witch, "as long as you can hear magic you will not lack a key to your prison. Sometimes it's better not to hear the other things. You are the ideal guest for the House of Living Alone." "I'll go and fetch David my Dog and Humphrey my Suit-case," said Sarah Brown. At that moment a taxi was heard to arrive at the other side of the ferry, and the ferryman's voice was heard shouting: "All right, all right, I'll be there in half a tick." "I hope this isn't Peony in a taxi," said the witch. "I get so tired of expelling guests. She's been drawing her money, which may have been tempting." They listened. They heard someone alight from the ferry-boat, and the voice of Miss Meta Mostyn Ford asking the ferryman: "Do you know anything about a young woman of the name of Watkins, living at Number 100 Beautiful Way----" "No, he doesn't," shouted the witch, opening the shop door. "But do step in. We met yesterday, you may remember. I'll ask the ferryman to get half-a-dozen halfpenny buns for tea, if you will be so kind as to lend me threepence. We don't bake ourselves." "I have had tea, thank you," said Miss Ford. "I have just come from a little gathering of friends on the other side of the river, and I thought I would call here on my way home. I had noted your address----" She started as she came in and saw Sarah Brown, and added in her committee voice: "I had noted your address, because I never mind how much trouble I take in following up a promising case." Sarah Brown, on first hearing that trenchant voice, had lost her head and begun to hide under the counter. But the biscuit-tins refused to make room, so she drew herself up and smiled politely. "How good of you to go to a little gathering of friends," said the witch, obviously trying to behave like a real human person. "I never do, except now and then by mistake. And even then I only stay when there are grassy sandwiches to eat. Once there were grassy sandwiches mixed with bits of hard-boiled egg, and then I stayed to supper. You didn't have such luck, I see, or you would look happier." "I don't go to my friends for their food, but for their ideas," said Miss Ford. Sarah Brown was gliding towards the door. "Oh, don't go," said the witch, who did not recognise tact when she met it. "I have sent Harold the Broomstick for your Dog David and your Suit-case Humphrey. He is an excellent packer and very clean in his person and work. Please, please, don't go. Do you know, I live in constant dread of being left alone with a clever person." "I must apologise for my intrusion, in that case," said Miss Ford, with dignity. "I repeat, I only came because I saw yours was an exceptional case."
