"Do you think there will be a mystery for us to solve these hols?" asked Bets. "I do so like looking for clues, and making out lists of Suspects, and crossing people off the list when we've made enquiries—and finding the real Suspect at the end!"

"We've been jolly lucky so far," said Pip, sitting up and looking round for the bottle of lemonade he had brought out. "We've been able to solve every single mystery. We can't always be successful, though. I don't expect even real detectives are always successful. Bets, you pig, you've finished the lemonade. Go and ask Gladys for some iced water."

Bets was too lazy to move. She rolled over out of Pip's reach, and yawned loudly. "I'm bored! I want the others to come back so that we can have games with them. I want a mystery—a really good one. And I want to solve it before Old Clear-Orf does!"

Old Clear-Orf was Mr. Goon the policeman. He told children and dogs to "clear-orf" whenever he saw them. He disliked all the Find-Outers intensely, and never had a good word to say for them. Pip and Bets hadn't seen much of him in the summer holidays, and were very glad, for he had often been to their parents to complain of the behaviour of the Five Find-Outers. Bets was afraid of him, because when he lost his temper he shouted, and was very unpleasant indeed.

"Bets, didn't you hear me tell you to go in and fetch some iced water?" said Pip crossly. "Go on!"

"I'm not going to be ordered about by you," said Bets, rolling a bit farther away. "I suppose you order all the little boys about in your school, and then when you come home you think you can order me about too. Well, I shall soon be ten, and you're not to!"

"Don't you cheek me, young Bets!" said Pip, sitting up. "You're much younger than I am, and you've got to do as you're told! Go and get that iced water—or I’ll catch you and give you a jolly good smacking."

"I think you're a horrid brother to have," said Bets. "I'd much rather have Fatty. He's always kind to me!"

"He wouldn't be, if you were his sister," said Pip. "He hasn't got any sisters—if he had, he'd know what a nuisance they are. Now—are you going to go and ..."

"Yes, I’ll get it!" said Bets, getting up, "but only because I'm thirsty, and I want some to drink, see? I don't mind bringing you out a little too, as I'm going to get some for myself, but I'm really going for myself, and..."
