Larry, Pip and Daisy got up and fled. They were not cowards, but really Mr. Hick was so very fierce that it honestly seemed as if he might throw them out., just as he had flung the kittens into the kitchen!

They ran up the drive - but half-way to the gate Larry stopped. "Wait till old Hiccup has gone out of the kitchen.," he said. "We simply must get Horace Peeks's address. We can't do anything about him till we know where he is."

They waited for a minute or two and then went back very cautiously to the kitchen. Mrs. Minns was talking to her sister, and Lily was still clattering about with the tea-things. The children put their heads round the door.

"What do you want now?" asked Mrs. Minns good-naturedly. "My word, you ran away like frightened mice! Made me laugh to see you!"

"You were just trying to think of Horace Peeks's address when Mr. Hick came in," said Larry.

"Was I, now?" said Mrs. Minns. "Well, it came into my mind in a flash, like - and now it's gone again. Let me see-letme see...."

She was thinking hard, and the children were waiting breathlessly, when the sound of heavy footsteps came up to the kitchen door and a loud knock was heard.

Mrs. Minns went to the door. The children saw that it was Mr. Goon, the policeman! They never seemed to be able to get away from old Clear-Orf.

"Morning, Mam," said Clear-Orf to Mrs. Minns, and he took out his large black notebook. "About this here fire - I think you've given me all the information I require. But I'd just like to ask you a few questions about that fellow Peeks."

The children frowned at one another. So Clear-Orf was after Peeks too!

"Do you know his address?" asked Clear-Orf, looking at Mrs, Minns out of his bulging pale-blue eyes.

"Well," said Mrs. Minns, "if that isn't a peculiar thing, Mr. Goon - I was just trying to think of his address

at the very moment you knocked! These children wanted to know it"

"What children?" said Clear-Orf in surprise. He put His head in at the door and saw Larry, Daisy and Pip.

"You again!" he said in disgust. "Clear orf! You kids are always popping up. You're a regular nuisance. What do you want Peeks's address for? Just nosey, I suppose?"

The children said nothing. Mr. Goon pointed back-wards with his thumb. "Go home I" he said. "I've private business to do here. Clear orf!

There was nothing for it but to "clear orf," and the children did so, running up the drive to the gate. They were very angry.

"Just as Mrs. Minns was thinking of the address!" said Larry.

"I hope she doesn't think of it and tell Clear-Orf," said Pip gloomily. "If she does, Clear-Orf will go over and see Peeks before we do."

"Blow!" said Daisy. They all felt very disheartened. They were just going out of the gate when they heard a low whistle from the bushes nearby. They turned back to see who it was.

Lily appeared, a letter in her hand. She looked fright-ened, but determined. "Will you post this letter for me?" she asked. "It's to Mr. Peeks, to warn him that people are saying he started the fire. But he didn't, he didn't. I know he didn't! You post the letter, will you?"

There was a shout from the kitchen. "Lily! Where are you?"

Lily disappeared at once. The children ran out of the gate, excited and surprised. They stopped behind a hedge when they had gone a little way, and examined Lily's envelope. It had no stamp on. The girl had forgotten it in her hurry.

"Golly!" said Larry, "here we've been all the afternoon trying to get Horace Peek's address and couldn't - and now, suddenly, it's just been presented to us, given into our hands!"

"What a bit of luck!" said Daisy, thrilled. "I am pleased."

"The thing is - do we want Peeks to be warned?" said Larry. "You see - if he is warned beforehand that people are suspecting him., he might run away. Then we shouldn't solve the mystery."

They all stared at one another. Then Pip had an idea, "I know! We'll go and find Peeks after tea today3 instead of wailing for tomorrow. We'll see him and try to make up our minds if he did it or not If we think he didn't do it, we'll give him Lily's letter!"

"Good idea!" said the others, pleased. "After all, we can't post a letter without a stamp - but we can deliver it by hand." They looked at the address.

Mr. H. Peeks. Ivy Cottage.

Wilmer Green.

"We'll go on our bikes," said Larry. "Come on - we must tell the others!"

The three of them went back to Fatty and Bets. Buster greeted them uproariously.

"Hallo," said Fatty, "how did you get on?"

"Awfully badly at first," said Larry, "and then, right at the end, we had a slice of good luck."

He told Bets and Fatty about the afternoon and they listened with the greatest interest. They all examined Peek's address, and were thrilled.

"So now Pip and Daisy and I are going on our bikes to Wilmer Green," said Larry. "It's only about five miles. At least, we'll have tea first and then go."

"I want to go too," said Bets at once.

"I'd like to go, but I believe I'm too stiff," said Fatty.

"You stay with Bets," said Pip. "We don't want to appear in a crowd. It might put Peeks on His guard."

"You keep leaving me out," said Bets sadly.

"No, we don't," said Larry. "Do you really want a job? Well, find out Mr. Smellie's address, see? Fatty will help you. It may be in the telephone book, or somebody may know it. We shall want His address tomorrow, because we must go and see him too. All the Suspects must be interviewed!"

"Two of them are crossed off now," said Pip. "Mrs. Minns didn't do it - and I'm sure the tramp didn't either. That only leaves Mr. Smellie and Mr. Peeks. I do wish we could find some one wearing rubber-soled shoes with those markings. It would be such a help!"

"I'll find out Mr. Smellie's address!" said Bets joyfully, pleased at having something real to do. "I'll bring the telephone book out here to Fatty."

The tea-bell rang. The children ran indoors to wash,, and were soon sitting down eating bread and butter and jam. Larry and Daisy stayed to tea, but Fatty had to go back to the hotel, as his mother was expecting him.

After tea Fatty came back and joined Bets. Larry and Pip and Daisy got out bicycles and cycled off. They knew the way to Wilmer Green quite well.

"What excuse shall we make for asking to see Horace Peeks?" said Larry, as they cycled quickly along.

Nobody could think of a good excuse. Then Pip had an idea. "Let's go to the house and just ask for a drink of water," he said. "If Peeks's mother is there I expect she'll talk nineteen to the dozen, and we may find out what we want to know - which is - where was Horace Peeks on the evening of the lire? If his mother says he was at home with her all the evening we can cross him off."

"Good idea!" said Larry. "And I'll tell you what I'll do, too; just before we get to the house I'll let the air out of my front tyre, see - and pumping up the bike will make a further excuse for staying and talking."

"Right!" said Pip. "I do think we are getting clever."

After some hard cycling they came to the village of Wilmer Green. It was a pretty place, with a duck-pond on which many white ducks were swimming. The children got off their bicycles and began to look for Ivy Cottage. They asked a little girl where it was, and she pointed it out to them. It was well set back from the road, and backed on to a wood.

The children rode to it, dismounted and went into the old wooden gate. Larry had already let the air out of his front tyre and it was almost flat.

"I'll ask for the water," said Daisy. They went up to the door, which was half-open. There was the sound of an iron going thump, thump, thump.
