"They might not be," said Pip. "Sorry, Mr. Goon, but we can't help you in the matter."

Larry thought it was about time to go, for Mr. Goon's face was turning a familiar purple. So he and the others hurriedly went back up the lane and made their way to Fatty's, longing to tell him all that had happened.

They found Fatty in the wood-shed at the bottom of his garden, trying to make himself a bit respectable. All his old-man clothes were in a sack, ready for use again. He was just smoothing down his hair when the others poured in.

"I say!" began Fatty, his eyes bright. "That was a bit queer, wasn't it? I mean—that man being so surprised to see me—and sitting down and saying things to me. I almost forgot I was deaf and shouldn't hear them!"

"What did he say?" asked Pip, and Fatty told him. The others listened breathlessly.

"And then up comes Goon, spots this fellow, and makes an awful to-do about adjusting his bike-chain, in order to have a good squint at the chap," said Larry.

“Looks suspicious to me. I mean—it looks as if Goon knew the fellow and wanted to know what he was up to."

"Is it a clue?" asked Bets eagerly.

"You and your clues!" said Pip scornfully. "Don't be silly, Bets."

"I don't think she is silly," said Fatty thoughtfully. "I think it is a clue—a clue to something that's going on—maybe even something to do with the Mystery. You know what the Inspector said—that it is thought that Peterswood may be the meeting-place of the thief-gang—the place where messages are passed on, perhaps, from one member to another."
