wore a really cute plaid shift dress with a ruffled collar, black tights, and boots.
Amber let out a yell. âGo, Claire!â she screamed.
She stood in front of the microphone and swung her guitar strap over her shoulder.
âIâll be singing âProm Queen,ââ Claire said. She began strumming her guitar and sang a song about a shy girl who nobody seemed to notice and who dreamed about becoming prom queen. Once again, Aly and AJ were impressed.
âI love it,â AJ whispered to Aly.
Claire left the stage and the audience waited for the final contestant, Austin. A minute or so went by and still the stage was empty. Muffled shouting seemed to be coming from backstage. Lily quickly disappeared behind the curtains to see what was going on. Aly and AJ got up and followed her.
The sisters poked their heads backstage. Josh and Claire were standing next to Austin, who was fuming.
âWhat happened?â Lily asked him as Aly and AJ walked into the room.
âMy guitar is totally out of tune!â Austin yelled. âI was getting ready to go onstage and luckily I strummed my guitar first. It sounded horrible so I went to tune it. But someone has loosened the screws on the back of the headstock.â Austin flipped his guitar over to show them.
âCanât you just tune it now?â Lily asked.
Austin shook his head. Aly took the guitar from him and examined it. âYouâre right. The screws are loose. You need a screwdriver to fix it before you can retune it,â she said.
âThis was no accident.â Austin was mad. âThe only way for this to happen is if someone took a screwdriver and loosened the screws.â
âHeâs right,â AJ said. âSomeone must have done this on purpose. Heâs lucky he found out before he went onstage.â
Claire held her guitar out to Austin. âUse mine,â she said. âI just finished playing it and I know itâs in tune.â
âIs everything okay?â Jim asked as he walked into the room.
âNot really,â Aly said. They grabbed Jim by the arm and led him to a quiet corner, explaining what had happened.
âCan you look around and see if Heather is here anywhere?â Aly asked. âSheâs been seen sneaking around here before. She might have had something to do with Austinâs guitar being sabotaged.â
âIâm going to add super-spy to my resume when weâre done in Seattle,â Jim joked. âIâll take a look around.â
Austin seemed to be calming down and was getting the feel of Claireâs guitar, so Aly and AJ headed back to their seats. The audience had grown restless, and a lot of people were talking to one another, wondering what was going on.
âIs this proof that Austin is innocent?â Aly asked AJ as they walked.
AJ shrugged her shoulders. âThis is the most confusing mystery yet. The notebook is stolen. Then someone puts it back. Heather is sneaking around and getting free pizza from Josh. Now someone has messed with Austinâs guitar. I donât know what to think!â
âMaybe Austin is some kind of evil genius,â Aly suggested. âHe might have sabotaged his own guitar to make us think that he is innocent.â
AJ sank into the red velvet theater seat and sighed. âIâm totally perplexed.â
They filled Carrie in on what was happening backstage. She shook her head.
âThatâs a shame,â she said. âThese kids have real talent. They donât need to stoop to cheating.â
The audience quieted down as Austin finally took the stage. Looking at him, no one would guess that heâd been so upset a few minutes ago. He looked cool, calm, and confidentânot to mention handsome. His long brown bangs were styled to the side and he had on an olive ribbed sweater with a half-zipper at the collar. Underneath he wore a black T-shirt and a pair of really nice faded jeans.
He
