But Pip was wrong. It was true that Mr. Goon had kept in bed for one day, but the next morning he was up and about, still sniffing and sneezing, but quite determined to go down to Milton House as soon as he could.

In fact, even as Pip was telling Bets that Mr. Goon would not be going down to Milton House for a bit, he was on his way there! He had to walk, because the snow was still lying thickly. He set off over the hill, and came to Chestnut Lane.

He noticed the car-wheels going down the lane, and wondered if they went as far as Milton House. He felt pleased when he saw that they stopped outside.

“Ho! Somebody coming to this old empty house in a fine big car!” said Mr. Goon to himself. “A bit funny, that. Yes - there’s something going on here - and those kids have got wind of it. Well, if they think they’re going to have another mystery all to themselves, they’re mistaken!”

Mr. Goon became all business-like. He hitched up his belt. He put his helmet more firmly on his round head. He walked very cautiously indeed to the gate of Milton House, trying to keep out of sight of the windows.

He saw the many footprints leading to and from the front door. He scratched his head, thinking hard. It looked as if people might be there. Were they the rightful owners of the place? What were they doing? And why did the children keep messing about there? Could it be that the thieves of the Sparling Jewels were there, hiding their booty?

Mr. Goon longed to get into that empty house. He longed to explore it. He wanted, however, to explore it without being seen. He felt sure the children had done so.

It was beginning to get dark, for it was a very gloomy, lowering winter’s afternoon, with more snow to come. Mr. Goon went cautiously round the house, and, to his enormous surprise, suddenly saw a black hole in the ground near the kitchen.

Almost at once he saw it was a coal-hole with the iron lid off. He stared at it in surprise. Had somebody got down there? Yes - one of those tiresome children, probably - and maybe they were even now exploring that house to find if any stolen goods were hidden there.

Mr. Goon’s face went slightly purple. He couldn’t bear to think that those children might get more praise from Inspector Jenks for finding stolen goods hidden in his, Goon’s, district. He determined to get into the house himself, find any of the children there, and scare the life out of them. My word, wouldn’t he shout at them!
