Ks are heavy enough,â I said. âAnd wait a secâwhere
are
the Ks?â I scanned our bedroom without seeing a single one. âOh, great. I wonder if they left at the same time the bug did. Maybe someone let them out.â
Tessa smiled. âKnow what, Cammie? This seems to me like the start of a mystery.â
Since we moved into the White House in January,Tessa, Nate and I have helped solve five mysteries. Weâve even been on TV! Grannyâs the one who taught us about detecting. Before she was a judge, she was a police officer.
âI donât think so, Tessa,â I said. âI mean, whereâs the bad guy? No one would steal a cockroach. Come onâJames Madisonâs got to be around here somewhere. Letâs keep looking.â
I peered under my bed, then Tessaâs. I looked under our dressers, then under each of the chairs. I looked in the closet and even in my shoes.
Tessa didnât look anywhere. She just stared at the tank.
âSome help you are,â I said.
âIâm thinking!â said Tessa. âIf the Ks didnât knock it over, who did?â
I shrugged. âHooligan, I guess.â
âOka-a-ay,â said Tessa. âSo say Iâm Hooligan.â She put her hands up like doggy paws and let her tongue loll out of her mouth. For a blond seven-year-old girl, she looked surprisingly like our big, furry, too-energetic dog.
Then she shoved the tank, and it tipped over. Only it didnât fall onto the floor. It stayed on the table. And the lid didnât come off, either.
Now I was interested. âOkay, so thatâs not what happened. How about if Hooligan banged into the table and made the whole thing tilt?â
Tessa made her Hooligan face again, dropped down on all fours andâ
bam!
âbumped her rear end into thetable with too much energy. Sure enough, the table tipped and the tank slid to the rug. Then it rolled once and came to rest upside down.
âHunh,â I said after a second. âIf it happened that way, James Madison couldnât have escaped. He wouldnât have had a way out.â
âAnd the dirt didnât spill, either,â Tessa said.
âMaybe it wasnât an accident,â I said.
âMaybe not.â Tessa was excited. âMaybe somebody just wanted it to look like one. And that would be a mystery! You know what I think? The First Kids are back in business!â
âNot right this minute theyâre not.â Charlotte had come in the door behind us. âBecause the First Kids are supposed to meet Ms. Major in the State Dining Room for photos.â Charlotte spotted the tank on the floor. âWhat happened?â
âJames Madison is gone,â I said.
Charlotte frowned. âWhat about Thomas Jefferson and George Washington? Are they still around?â
âNot President James Madison!â Tessa waved her arms. âThe bug James Madison!â
Charlotte pressed a button on her radio. âHang on while I tell Mr. Ross.â
âNo-o-o!â
Tessa whined. âMr. Ross will get out the bug spray for sure!â
Charlotte muted the radio. âGirls, be real. The White House canât host a formal dinner when thereâs a foreign cockroach on the loose.â
Tessa glared at me. âCammie, you never shouldhave told Charlotte! In the end, sheâs just a grown-up, and sheâs on the grown-up side.â
Charlotte protested. âHey, no fair. I used to be a kid! I even had a pet iguana that one time ran away and scared the neighborsâ dogs.â
âDid you get it back?â I asked.
âYeah, but then Mom sent it to live in a swamp in the country. At leastââCharlotte looked thoughtfulââthatâs where she told me it went. All right. I wonât tell Mr. Ross . . . yet.â
I said, âThank you,â and Tessa gave Charlotte a great big hug.
âBut hurry and get dressed
