and was a better pitcher than most of the kids on the fourth-grade baseball team, including Sean. But to him the sickening thing about Debbie Jean was that she always had to be right about everything. Just once, Sean wished Debbie Jean could be wrong about something.
Mrs. Jackson glanced at the clock, then made an announcement to the class.
âIâm pleased that all of you remembered to turn in your permission slips for our field trip to the museum tomorrow,â she said.
The field trip! Sean realized that he had forgotten to tell Brian about his classâs upcoming trip to the museum! Heâd have another chance to look around the museum for clues without anyone on the museum staff becoming suspicious. But what kind of clues? Sean wondered.
âThe museumâs curator will be telling us the stories behind some of the paintings in their exhibit of American primitive art,â said Mrs. Jackson, âso be sure to bring notebooks and pencils. After the trip Iâll expect each of you to write a report about what you saw and learned.â
A few kids groaned, but the bell rang and Mrs. Jackson dismissed the class for the day.
Sean grabbed his books, stuffed them into his backpack, and ran all the way to the museum, where Brian was waiting for him.
âI have a plan,â Brian said as soon as Sean came up the steps.
Sean smiled. Brian always came up with some kind of a plan.
âWeâre going to start with a search of the first exhibit room on the rightâthe early weapons room. Weâll check out as many of the exhibit rooms as we can. If we keep our eyes open, maybe weâll see something that might look suspicious, or strange, or out of place.â
âBut Mrs. Gomez said the police already searched the museum last night,â Sean said.
âThatâs true,â Brian said. âBut we might discover something the police missed.â
Brian and Sean entered the museum.
âLook,â whispered Sean. âThe museum guard is watching us. Do you think he knows what weâre doing?â
âDonât worry about him,â Brian said. âThe minute grown-ups see kids hanging around, they start worrying that theyâre going to break stuff or make noise. Itâll never occur to the guard that weâre investigating a crime.â
Sean froze, however, when he saw the guard heading toward them.
âUh-oh,â he whispered to Brian.
âYouâll have to check those backpacks and jackets, boys,â the guard said. Then he walked away.
Brian looked at Sean. âSee, I told you.â
Brian and Sean checked their bags and jackets and entered the large main room of the museum, where the special exhibits were displayed.
A series of movable screens were arranged in a square in the center of the room and were hung with paintings belonging to the exhibit of American primitive art. Only a few people were viewing the exhibit. At this late afternoon hour there werenât many museum visitors.
On a far wall Brian saw a poster that announced the dates of the coming exhibit from the Metropolitan Museum of Art.
âC'mon,â Brian said, and he and Sean entered the early weapons room, in which were displayed weapons dating back to the Civil War and the frontier days of the American West.
Brian immediately began examining the undersides of the glass display cases, checking to see if the stolen sketches could be hidden either underneath or inside them.
âHey, come here, Bri!â Sean called out. âLook at this cane thatâs in two pieces. The handle has a short sword that can be hidden inside the cane.â
Sean pressed his face closer to the glass.
âNeat,â he said. He turned to Brian. âSomeone could just pull on the carved top of the cane and zap! Out comes the sword! Wow! If I had a sword like this one, Iâd go like wham and zap and whoosh! â
âWeâre supposed to be looking for
