"I don't even know where the key's kept now," said Luke.

"I usually have it in my pocket, except on the days when I go out," said Miss Harmer. "Then I give the key to Tupping. What do you do with it, Tupping?"

"I keep it in my pocket, too," said Tupping. "But I left my coat along here somewhere this afternoon, so Luke could easily have got at the key. Mark my words, Dark Queen is hidden somewhere about, ready for somebody to fetch away! I knew you'd be sorry, Madam, if you took that boy back again. Stands to reason something of this sort will happen if you do that I said many a time to Mr. Goon —"

"I am not interested in what you say to Mr. Goon," said Lady Candling. "I think we will go over Mr. Goon's head this time and get in touch with Inspector Jenks immediately."

The children were simply delighted to hear this; but, alas, the good Inspector was away, so Mr. Goon had to be notified, and arrived, full of importance, to look for clues and to hear what everyone had to say.

He looked suspiciously at the five children. Then he looked at the cages as if he expected to find a whole lot of dues there again. But there was nothing to see except the whistle which Lady Candling had given him.

"You found any dues this time?" said Clear-Orf to Fatty.

"We've only found a smell and a stone with paint on it," said Bets. The others frowned at her so suddenly and severely that she nearly ran away.

"A smell?" said Mr. Goon disbelievingly. "And a stone with paint on? Ho! so you think you can trick me again, do you — with smells and stones this time!"

With that Mr. Goon turned his back on the children, who at once went to the wall, climbed over it, and sat down to talk about this new happening.
