and sat down beneath the shade of an old oak tree by the old boxcar that had once been their home.
âWhat are we going to do now?â Violet repeated.
âMaybe we should talk to Professor Madison again,â said Henry.
Jessie said, âItâs true, sheâs acted pretty strangely. But if that man really was trying to break into her house and steal the cat, that would explain it.â
â If sheâs telling the truth,â said Henry.
âBut why would Professor Madison steal a cat when she already has so many?â asked Violet.
âThatâs true,â said Henry.
Suddenly Jessie said, âWhitney!â
Henry, Violet, and Benny looked at her in surprise. âWhat about Whitney?â asked Henry. âShe couldnât have had anything to do with Spotzieâs disappearance. Spotzie disappeared before Whitney ever arrived.â
âBut what if Whitney is the one making the mysterious phone calls? What if there is no Mr. Jones at all?â asked Jessie.
âWhy would Whitney do that?â Benny wanted to know.
Jessie furrowed her brow. âBecause ⦠because she thinks weâre just children and we canât solve this case. Maybe itâs a practical joke?â
Benny shook his head. âIt would be a mean joke!â he declared.
âI wonder if Whitney would do something like that?â said Violet. âI donât think she would.â
After a moment, Jessie nodded her head in agreement with Violet. âYouâre right, Violet. I guess I donât think she would, either.â
âWell, what about Mr. Allen?â suggested Henry. âDid you notice he seemed surprised when he saw Spotzieâs photograph â almost as if he recognized her.â
âThatâs true,â Jessie said.
âYes, he did act surprised,â said Violet. âBut why would he lie about ever having seen Spotzie?â
âMaybe he has Spotzie!â cried Benny.
âBut why, Benny,â said Jessie. âWhy would he want Spotzie when he has so many other beautiful cats?â
âMr. Jones, whoever he is, is the most likely âcat burglar.â We have to find him to solve the mystery and find Spotzie.â
âBut how?â said Jessie. âHow are we going to find Mr. Jones?â
Henry said, âWait a minute. Iâve thought of a way we could find Mr. Jones.â
âHow?â cried Jessie excitedly.
âWe wrote to him at a post office box,â said Henry. âBox number ninety-three. All we have to do is watch the post office and see who comes to get the mail out of that box.â
âOh, Henry, thatâs a wonderful idea!â exclaimed Violet.
âWeâll be like spies,â said Benny. âWill we need disguises?â
Everyone smiled at that. âNo, Benny,â said Henry. âBut we will be like spies, sort of, watching for Mr. Jones to see who he really is.â
Benny nodded. âWe can take Watch to watch for Mr. Jones.â
âWeâll do that,â said Henry. âWe can take turns, Benny. You and Watch and Jessie can watch tomorrow morning. Then Violet and I will come up to watch for a while.â
âCan Soo Lee come, too?â asked Violet.
âYes, of course,â said Henry. âThe more people we have helping us, the better!â
CHAPTER 10
The Chase Is On
J essie, Benny, and Watch were waiting at the Greenfield Post Office when it opened the next morning. It was a bright, sunny day. The post office was surrounded by shady trees and had windows across the front.
Jessie, Benny, and Watch were about to go in and find box 93 when Jessie noticed a sign on the post office door: N O D OGS A LLOWED .
âYou and Watch will have to wait out here,â she said, pointing to the sign. Benny sounded out the words slowly and then looked at his sister.
âWhy arenât dogs allowed in the post office?â he asked. âI
