"Well, I'm blessed!" said Fatty, looking down at his dirty hands, and examining the well-kept nails. "Who would have thought of any one noticing that? Very very careless of me not to get some dirt into my nails when I made my hands filthy. I never thought of it. Bets, you are very clever. Most intelligent."

"Oh, Fatty—not really," said Bets, glowing all over her face at such generous praise.

"Well, I must say I think it was jolly cute of young Bets to notice a thing like that," said Larry. "I really do. We all had a chance of noticing, because we all stood in front of you. But it was Bets who spotted it. Jolly good, Bets!"

"She wins my second-best propelling-pencil," said Fatty. "I'll give it to you when I get home, Bets. In fact I'm not sure that I oughtn't to give you my best one. That was a really smart bit of work. Bright enough for a first-class detective!”

Daisy praised Bets too, but Pip was rather sulky. He was afraid his little sister would get swollen-headed. "If you say much more, Bets will want to be head of the Find-Outers," he said.

"Oh no, I shan't," said Bets happily. "I know it was only a bit of luck, really, Pip. You see, I actually put the pennies into Fatty's hands, and that's how I noticed the clean nails. Pip, I’ll lend you the propelling-pencil whenever you want it. See?"

That was so like Bets. Not even a cross elder brother like Pip could sulk for long with Bets. He grinned at her.

"Thanks, Bets. You're a good Find-Outer, and a good little sport too!"

"I say—look out—here's Goon!” suddenly said Larry, in a low voice. "Better pretend we're not with Fatty, or Goon will wonder why we are hobnobbing with an old Fair woman!"

So they all got up, and left Fatty behind on the seat, with his string of balloons bobbing over his head. Mr. Goon was on his bicycle as usual. He pretended not to notice the children at all. He always seemed busy and important these days!
