Mr. Goon grunted bad-temperedly. Those children again! They seemed to turn up everywhere.

"You having a lemonade too?" said Pip. "Have one with us, Mr. Goon. Do."

Mr. Goon grunted again, and returned to his newspaper. He was in plain clothes and looked rather strange. The children couldn't remember ever having seen him in anything but his rather tight-fitting uniform before. He wore flannel trousers, a cream shirt open at the neck, and a belt that he had pulled too tight. Bets thought he didn't look like Mr. Goon at all.

She finished her lemonade. "I'm going to buy a balloon," she said. "The one I bought at the Fair has gone pop. Order me an ice, Pip, and I'll be back to have it soon. We are all going to have ices, aren't we?"

"Where's that fat boy?" asked Mr. Goon, as Bets got up.

"Fat boy? What fat boy?" said Larry at once, pretending to be puzzled.

Mr. Goon gave a snort. "That boy Frederick. Fatty, you call him. You know quite well who I mean. Don't act so daft."

"Oh, Fatty! He's not far off," said Larry. "Do you want to see him? I'll tell him, if you like."

"I don't want to see him," said Mr. Goon. "But I know he's always up to something. What's he up to now?"

"Is he up to something now?" said Larry, a surprised look on his face. "How mean of him not to tell us!"
