"What you out here for, in the morning?" said the man suddenly, in a very low voice. "Thought you never came till the afternoon. Anything up? Expecting any one?"

Fatty was taken aback to hear this low and confidential whisper. Obviously the man thought him to be the old fellow, and was amazed to see him out in the morning. But what did all the questions mean?

Just in time, Fatty remembered that the old man was deaf. He put his hand to his ear and put his ear towards the man, so that he should not look directly into his face. He was afraid that he might be recognized as a fraud if the man looked into his eyes.

"Wassat?" said Fatty, in a croaking old voice. "Wassat?"

The man gave an impatient exclamation. "Of course—he's deaf!" He gave a quick look round as if to see if any one was near. Then somebody else cycled slowly by and the man sidled a little way away from Fatty, and took out a cigarette to light.

The cyclist was Goon, perspiring freely in the hot sun. He saw the two men at once, and got off his bicycle. He pretended to adjust the chain. The four children in the shop watched him with interest, hoping that he wouldn't go and say anything to Fatty.

Buster saw Goon, and with a delighted yelp he tore out of the sweet-shop, and danced round the policeman's feet. Larry rushed after him, afraid that Buster would go and lick Fatty's face, and give the show away to Goon. But Buster was fully engaged with the angry policeman, and was having a perfectly lovely time, dodging kicks, and getting in little snaps and snarls whenever he could.

Fatty got up hurriedly and shuffled away round the nearest corner without being noticed by Mr. Goon, who was rapidly losing his temper. All the others, seeing Fatty wanted to get away before Goon noticed he was gone, began to join in the fun, pretending to call Buster off, but only succeeding in exciting the little Scottie more than ever!

When at last Buster was safely in Larry's arms, and Goon could look round at the bench, it was empty! Both the men had gone. Mr. Goon looked extremely angry.

"That there dog!" he said, dusting his trousers down violently. "I'll report him, I will. Interfering with me doing my duty, that's what he did. And now where are them two fellows gone? I wanted to put a few questions to them!"

"They've disappeared," said Daisy. Mr. Goon did one of his snorts.

"No need to tell me that. I've got eyes in my head, haven't I? I may have lost a Most Important Clue! See? Where's that fat boy that's always with you? I bet he's at the bottom of this!"

"He isn't here," said Larry truthfully. "You'll probably find him at home if you badly want to see him, Mr. Goon."

"I wouldn't care if I never set eyes on him again, the cheeky toad!" said Mr. Goon, mounting his bicycle rather ponderishly and wobbling a little. "No, nor any of you neither. As for mat dog!"

He was about to ride off, when he stopped, wobbled again, and spoke to Larry.

"Where were you just now?"

"In the sweet-shop, having lemonade," said Larry. "Ho," said Mr. Goon. "And did you see that old fellow sitting on that bench?"

"Yes, we did," said Larry. "He seemed half-asleep and quite harmless."

"And did you see that other fellow talking to him?" demanded Mr. Goon.

"Well—he may have spoken to him. I don't know," said Larry, wondering why the policeman was asking all these questions.

"You'd better come alonga me," said Mr. Goon, at last. "I'm going to call on that old fellow, see, and I want you to back me up when I tell him I want to know about the other fellow."

The children felt distinctly alarmed. What! Mr. Goon was going to visit the real old man—who would probably be in bed—and ask him questions about the other man, whom he hadn't been there to see! Whatever would the poor old fellow say? He wouldn't in the least know what Mr. Goon was talking about!

"I don't think we've got time to ..." began Larry. But Mr. Goon pooh-poohed him.

"It's my orders," he said pompously. "You may be witnesses. You come alonga me."

So the children went with Mr. Goon, Buster struggling wildly against the lead to get at the policeman's ankles. They turned one or two comers and came to a dirty little pair of cottages at one end of a lane. Mr. Goon went to the first one and knocked.

There was no answer at all. He knocked again. The children felt uncomfortable and wished they were at home. No answer. Then Mr. Goon pushed hard at the door and it opened into a room that was plainly half sitting-room and half bedroom. It was very dirty and smelt horrid.

In the far corner was a small bed, piled high with dirty bedclothes. In it, apparently asleep, his grey hairs showing above the blanket, was the old man. His clothes were on a chair beside him—old coat, corduroy trousers, shirt, muffler, hat, and shoes.

"Hey, you!" said Mr. Goon, marching in. "No good pretending to be asleep, see? I saw you a few minutes ago in the village street, on the bench."

The old man awoke with a jump. He seemed to be extremely surprised to see Mr. Goon in his room. He sat up and stared at him. "Wassat?" he said. It really did seem to be about the only thing he could say.

"It's no good pretending to be in bed and asleep," roared Mr. Goon. "You were on the bench in the middle of the street just now. I saw you!"

"I ain't been out of this room today!" said the old man, in a cracked voice. "I always sleeps till dinner, I do."

"You don't," shouted Mr. Goon. "You didn't today. And I want to know what that fellow said to you when he came and sat beside you on the bench. Now you tell me, or it'll be the worse for you!"

Bets felt sorry for the old man. She hated it when Mr. Goon shouted so. The old fellow looked more and more puzzled.

"Wassat?" he said, going back to the word he loved.

"See these children here?" said Mr. Goon, beside himself with annoyance at the old man's stupidity. "Well, they saw you there too. Speak up now, you kids. You saw him, didn't you? "

"Well," said Larry, hesitating. "well ..." He really didn't know what to say. He knew quite well it hadn't been the old man on the bench—and yet how could he say so without giving Fatty away?

Pip saw his difficulty and rushed in with a few clever words. "You see, Mr. Goon, it's difficult to say, isn't it, because an old man in bed and an old man dressed don't look a bit the same."

"Well, look at his clothes then," said Mr. Goon, pointing to the clothes. "Aren't those the very clothes he was dressed in?"

"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."
