“And if another mystery doesn’t crop up, we’ll have the fun of practising for it anyway,” said Bets.
“Right,” said Fatty, “but I think if I am going to teach you all these things I ought to be the head of the Find-Outers, not Larry. I know Larry’s the oldest - but I think I know more about these things now.”
There was silence. Larry didn’t want to give up being head, though in fairness he had to admit that Patty was really the cleverest at spotting things when they had a mystery to solve.
“Well, what about it?” said Fatty .“I shan’t give away my secrets if you don’t make me head.”
“Let him be head, Larry,” said Bets, who admired Fatty tremendously. “Head of the next mystery anyway, whatever it is. If he isn’t as clever as you at solving it, then we could make you head again.”
“All right,” said Larry. “I do think Fatty would make a good head, really. But if you get conceited about it, Fatty, we’ll sit on you hard.”
“You needn’t tell one that,” said Patty, with a grin.
“Right-o! I’ll be head. Thanks, Larry, that was sporting of you. Now I can teach you some of the things I know. After all, you simply never know when they might come in useful.”
“It might be very, very important to be able to write a letter in invisible ink,” said Bets. “Oh, Fatty, do teach us something now.”
But Bets’ mother just then put her head in at the playroom.
