they usually get. So a C student gets a C answer keyâor maybe a C+. But itâs always in the normal range. The higher the grade, the more expensive the cheat sheet. Hannah says they range from seven to twenty dollars.â
âYouâre kidding!â I squeaked. âHow many customers does this guy have?â
âAccording to Hannah, about ninety percent of the kids buy in. Draper has two biology classes and two math classes. Thatâs about a hundred and twenty kids. If ninety percent of them take part, thatâs a hundred and eight kids. Letâs say one week thereâs a math and biology test. If the guy averages twelve dollars a sale, he would makeââthere was a pause as she worked the calculation in her headââabout thirteen hundred dollars.â
âWow,â I breathed. âThatâs a lot of money. By the way, do you know you sound like a math problem?â
Liz chuckled.
âDid your sister say anything else?â I ask.
âYeah. Apparently our genius lives close to the school. The sales take place at his house during lunch.â
âSo how do the kids hand in their cheat sheets? Does our scammer make the switch?â
âNo. The only risk he takes is copying the original answer key. The kids have to figure out how to switch the sheets on their own. Most of them smuggle them into the test under their shirts and make the switch sometime near the end of the class when Draper isnât looking.â
âAnd nobodyâs been caught?â
âNot a single person.â
âAnd nobodyâs squealed?â
âNot yet.â
âWell, itâs time somebody did.â
I rolled onto my stomach again and saw Jack standing in the doorway. Heâd obviously been listening.
He sent me a look that was a combination of pity and disgust, shook his head and walked away.
Chapter Nine
Liz had said the guy behind the scam lived close to the school. Sean lived close to the school. That was one more strike against him. I was sure he hadnât snagged the answer key when Iâd seen him in Draperâs classroom, but he couldâve gotten it since. With the test date creeping up, he might be in selling mode. It was time to keep an eye on him.
I decided to tail him at lunch on Friday. I tore off toward his locker as soon as the bell rang. As I waited for him to show up, I tried to get lost in the mob of kids dumping off books and grabbing lunches.
It wasnât long before Sean showed. He crammed his books into his locker and took off. I followed him to the exit and watched as he jogged across the field toward his house. All I had to do was wait. Once he was out of sight, Iâd follow. There were bushes near his house where I could hide and spy on anyone who paid him a visit.
As I went to push open the door, a hand gripped my arm.
It was Jack.
âWhat do you think youâre doing?â he sneered.
âItâs none of your business,â I snapped. âAnd let go of me.â I yanked my arm free.
âYouâre following Sean,â he said. âIâve been watching you.â He didnât look amused. âYouâre a crappy detective, Laurel. The only one getting caught is you.â
I glared at him and reached for the door again, but again he grabbed my arm. This time it hurt.
âI mean it, Laurel,â he said through gritted teeth. âBack off. Sean is my friend. Iâm not going to let you drag him through the mud just so you can get a stupid newspaper story.â
I opened my mouth to argue, but he cut me off.
âAll youâre doing is looking for glory. You donât give a rip about the people youâre hurting.â
âSo you admit Seanâs guilty,â I sneered.
It was like Jack was a blow-up doll, and Iâd just stuck him with a pin. His shoulders sagged, and his head drooped. âYou donât get it, do you? Iâm asking you to leave this
