It is the very spot in which to begin our researches."

A murmur of approval arose from the other members of the committee.

"I don't know whether it's occupied or not," said Aunt Amanda. "Ketch told me that no one lives there, and that there's thirteen of 'em; and he seemed to be afraid of the place. And there's a light up there. I don't understand it."

"Gentlemen," said the Third Vice-President, "is it the sense of the committee that we begin our researches in Low Dudgeon?"

Every member of the Daft Committee murmured his assent.

"If we go into the forest," said Toby, "we may be caught; if we go in here, we are safe for a while, anyway, and we can decide there what we had better do; maybe these gentlemen can send for help. Anyway, let's get in if we can."

"Better knock," said Toby.

They knocked, and knocked again; there was no answer.

"Aunt Amanda," said Toby, "try your key."
