the open trapdoor and the short folding ladder that stood open beneath it.
âShine your spotlight down there,â Sean told Debbie Jean. âI want to take a picture.â
âLook at all the footprints in the dust!â Brian said. âThere are a lot of big ones Miss Beezly didnât make. And ghosts donât leave footprints!â
âThatâs weird,â Sam said, and pointed. âDo you see those places where the ladderâs glowing?â
Brian climbed down a few rungs to take a closer look. âItâs green phosphorescent paint,â he said.
âI bet itâs the same stuff that was on whoever was pretending to be a ghost,â Sean said.
âYou mean the ghost isnât real?â groaned Debbie Jean. Sean thought she sounded disappointed.
â That ghost may not have been real. But donât forget,â said Sam, slipping into his scary voice, âHoratioâs supposed to be hanging around here somewhere.â
âDonât do that!â Sean snapped nervously.
âWhatâs the matter, Sean?â asked Debbie Jean. âAre you scared?â
âNo,â said Sean defensively. âAnd anyway, Iâm not the one who practically set a world record running away!â
âOh yeah?â said Debbie Jean.
âYeah!â said Sean.
âCut it out, both of you,â Brian said as he climbed up the ladder of the trapdoor onto the stage. âWeâre dealing with somebody whoâs pretending to be a ghost, and we donât know why.â
âSo what do we do now?â asked Sam.
âWe look for a motive,â Sean said, and Brian nodded. Sean knew how Brianâs mind worked when they were investigating a case.
âYouâve got a motive,â Sam said. âI could see those women from the historical society being real interested in the idea of a ghost that would lure tourists to the theater after itâs restored.â
âBut why would the ghost want to scare us away?â Sean asked. âWeâre not working for Mr. Marconi.â
âBut we are working to help Dad on this case,â Brian said. He stared at Sean. âAnd some of us might believe in ghosts and spread the word that the theater is haunted. You saw how interested that reporter was about Horatio.â
âYeah,â Sean agreed. âSince that article came out I bet most of Redoaks believes the Culbertson is haunted.â
Brian pulled out his notebook and turned back a few pages. âLetâs go over some of what we already know.â He began reading. âA heavy flat almost hit Mr. Marconi. A stair railing broke, and he fell. Then on Saturday a sandbag landed on his inspectorâs shoulder.â
âAnd donât forget that today the battens nearly clobbered me!â Sean said.
âAnd donât forget that both Mr. Marconi and Mrs. Hemsley have big investments in the land around the Culbertson,â Debbie Jean added.
âWhatâs really strange,â Brian said, âis that the ghost didnât appear to Mr. Marconi or the inspector. We were the firstâand onlyâones to see it.â
âAha!â Sam said, jabbing a finger into the air. âThat sounds like a clue.â
âThe answer might be an important clue,â said Brian as he tucked his notebook into his pocket. âBut before we can know for sure weâll need to see more of this theater, like the dressing rooms and all the backstage places where someone could hide and put on costumes and paint. It might make it easier to learn who our ghost is.â
âYeah,â Sam said. âMr. Peabody said somebody had disturbed the theater stuff.â
âAre we going back there now?â Sean asked.
âSure. Now,â Brian told him.
Sean turned to Debbie Jean. âIâll trade you my flashlight for your superspotlight.â
âNo way,â Debbie Jean said.
Brian walked toward
