“On both sides,” said Mr. Gubb, “and who comes to your house most?”

“Well, I declare!” said Miss Petunia. “I don’t know what you are getting at, but on one side I have no neighbors at all, and on the other side is Mrs. Canterby. I guess she comes to my house oftener than anybody else.”

“I am acquainted with Mrs. Canterby,” said Mr. Gubb. “I did a job of paper-hanging there only last week.”

“Did you, indeed?” said Miss Scroggs politely. “She’s a real nice lady.”

“I don’t give opinions on deteckative matters until I’m sure,” said Mr. Gubb. “She seems nice enough to the naked eye. I don’t want to get you to suspicion her or nobody, Miss Scroggs, but about the only clue I can grab hold of is that first letter you got. It said to look on page fourteen, and all the pages by that number was torn out of your books—”

“Except my cook-book,” said Miss Petunia.

“And a person naturally wouldn’t go to think of a cook-book as a real book,” said Mr. Gubb. “If you stop to think, you’ll see that whoever wrote that letter must have beforehand tore out all the page fourteens from the books into your house, for some reason.”

“Why, yes!” exclaimed Miss Scroggs, clapping her hands together. “How wise you are!”

“Deteckative work fetches deteckative wisdom,” said Mr. Gubb modestly. “I don’t want to throw suspicion at Mrs. Canterby, but Letter Number One points at her first of all.”
