The children looked, and there, splashed on the toes of the rubber boots, were drops of the creamy-brown paint! Tupping must have worn the boots when he painted the cat's tail! And it was he, of course, who must have dropped a blob of paint on to the stone that Fatty had in his pocket. Probably off the paint-brush.

"We'll take these boots, and the hanky too," said Fatty importantly. "Come on, Buster. We've got some mighty good clues and bits of evidence, I must say. What a shock dear Mr. Tupping is going to get when he hears all we have to say."

They went out of the shed and came face to face with Luke, who still looked very gloomy. "You're going to get into trouble," he said to Fatty. "Tupping's gone down to get Goon, because he says he found you in the cat-house, and he says it must have been you children who took that cat. I suppose he's going to make out that you did it when I was there, and I didn't let on, so as to shield you. You're going to get into trouble!"

The End of it All

Fatty went off to telephone to Inspector Jenks. He was lucky enough to get him straight away.

"Please, Inspector Jenks," said Fatty, "we've solved the Mystery of the Disappearing Cat. Could you possibly come over and let us tell you?"

"Well," said the Inspector, "I've just had a most mysterious message from Goon — something about finding you children in the cat-house, and saying he thought you had something to do with the disappearance of the cat — and I was thinking of coming over anyway."

"Oh, good!" said Fatty joyfully. "Are you coming to Lady Candling's?"

"Yes, that would be best," said the Inspector. "Meet me there in an hour's time, will you?"

Fatty went back to tell the others — to find them all in a state of great indignation. Mr. Goon had been to Bet's mother and complained to her that the little girl had been caught trespassing in the cat-house. He had now gone to tell Fatty's mother that Fatty had been caught there too.
