A Wal-Mart employee just a little older than us walked up to us then and said, “Hey, you can’t use that in here,” and Margo said, with seeming sincerity, “Sorry, I didn’t know that,” and the guy said, “Oh, it’s cool. I don’t mind, actually.” And then the conversation seemed over, except the guy could not stop looking at Margo, and honestly I don’t blame him, because she is hard to stop looking at, and then finally he said, “What are you guys up to tonight?”

And Margo said, “Not much. You?”

And he said, “I get off at one and then I’m going out to this bar down on Orange, if you want to come. But you’d have to drop off your brother; they’re really strict about ID’s.”

Her what?! “I’m not her brother,” I said, looking at the guy’s sneakers.

And then Margo proceeded to lie. “He’s actually my cousin,” she said. Then she sidled up to me, put her hand around my waist so that I could feel each of her fingers taut against my hip bone, and she added, “ Andmy lover.”

The guy just rolled his eyes and walked away, and Margo’s hand lingered for a minute and I took the opportunity to put my arm around her. “You really are my favorite cousin,” I told her. She smiled and bumped me softly with her hip, spinning out of my embrace.

“Don’t I know it,” she said.

We were driving down a blessedly empty I-4, and I was following Margo’s directions. The clock on the dashboard said it was 1:07.

“It’s pretty, huh?” she said. She was turned away from me, staring out the window, so I could hardly see her. “I love driving fast under streetlights.”

“Light,” I said, “the visible reminder of Invisible Light.”

“That’s beautiful,” she said.

“T. S. Eliot,” I said. “You read it, too. In English last year.” I hadn’t actually ever read the whole poem that line was from, but a couple of the parts I did read got stuck in my head.

“Oh, it’s a quote,” she said, a little disappointed. I saw her hand on the center console. I could have put my own hand on the center console and then our hands would have been in the same place at the same time. But I didn’t. “Say it again,” she said.

“Light, the visible reminder of Invisible Light.”

“Yeah. Damn, that’s good. That must help with your lady friend.”

“Ex-lady friend,” I corrected her.

“Suzie dumped you?” Margo asked.

“How do you know shedumped me?”

“Oh, sorry.”

“Although she did,” I admitted, and Margo laughed. The breakup had happened months ago, but I didn’t blame Margo for failing to pay attention to the world of lower-caste romance. What happens in the band room stays in the band room.

Margo put her feet up on the dashboard and wiggled her toes to the cadence of her speaking. She always talked like that, with this discernible rhythm, like she was reciting poetry. “Right, well, I’m sorry to hear that. But I can relate. My lovely boyfriend of lo these many months is fucking my best friend.”

I looked over but her hair was all in her face, so I couldn’t make out if she was kidding. “Seriously?” She didn’t say anything. “But you were just laughing with him this morning. I saw you.”

“I don’t know what you’re talking about. I heard about it before first period, and then I found them both talking together and I started screaming bloody murder, and Becca ran into the arms of Clint Bauer, and Jase was just standing there like a dumbass with the chaw drool running out of his stank mouth.”

I had clearly misinterpreted the scene in the hallway. “That’s weird, because Chuck Parson asked me this morning what I knew about you and Jase.”

“Yeah, well, Chuck does as he’s told, I guess. Probably trying to find out for Jase who knew.”

“Jesus, why would he hook up with Becca?”

“Well, she’s not known for her personality or generosity of spirit, so it’s probably because she’s hot.”

“She’s not as hot as you,” I said, before I could think better of it.

“That’s always seemed so ridiculous to me, that people would want to be around someone because they’re pretty. It’s like picking your breakfast cereals based on color instead of taste. It’s the next exit, by the way. But I’m not pretty, not close up anyway. Generally, the closer people get to me the less hot they find me.”

“That’s— ” I started.

“Whatever,” she answered.

It struck me as somewhat unfair that an asshole like Jason Worthington would get to have sex with both Margo andBecca, when perfectly likable individuals such as myself don’t get to have sex with either of them — or anyone else, for that matter. That said, I like to think that I am the type of person who wouldn’t hook up with Becca Arrington. She may be hot, but she is also 1. aggressively vapid, and 2. an absolute, unadulterated, raging bitch. Those of us who frequent the band room have long suspected that Becca maintains her lovely figure by eating nothing but the souls of kittens and the dreams of impoverished children. “Becca does sort of suck,” I said, trying to draw Margo back into conversation.

“Yeah,” she answered, looking out the passenger window, her hair reflecting oncoming streetlights. I thought for a second she might be crying, but she rallied quickly, pulling her hoodie up and taking The Club out of the Wal-Mart bag. “Well, this’ll be fun at any rate,” she said as she ripped open The Club’s packaging.

“May I ask where we’re going yet?”

“Becca’s,” she answered.

“Uh-oh,” I said as I pulled up to a stop sign. I put the minivan in park and started to tell Margo that I was taking her home.

“No felonies. Promise. We need to find Jase’s car. Becca’s street is the next one up on the right, but he wouldn’t park his car on her street, because her parents are home. Try the one after. That’s the first thing.”

“Okay,” I said, “but then we go home.”

“No, then we move on to Part Two of Eleven.”

“Margo, this is a bad idea.”

“Just drive,” she said, and so I just did. We found Jase’s Lexus two blocks down from Becca’s street, parked in a cul-de-sac. Before I’d even come to a complete stop, Margo jumped out of the minivan with The Club in hand. She pulled open the Lexus’s driver-side door, sat down in the seat, and proceeded to attach The Club to Jase’s steering wheel. Then she softly closed the door to the Lexus.

“Dumb bastard never locks that car,” she mumbled as she climbed back into the minivan. She pocketed the key to The Club. She reached over and tousled my hair. “Part One — done. Now, to Becca’s house.”

As I drove, Margo explained Parts Two and Three to me.

“That’s quite brilliant,” I said, even though inside I was bursting with a shimmering nervousness.

I turned onto Becca’s street and parked two houses down from her McMansion. Margo crawled into the wayback of the minivan and returned with a pair of binoculars and a digital camera. She looked through the binoculars first, and then handed them to me. I could see a light on in the house’s basement, but no movement. I was mostly surprised that the house even hada basement — you can’t dig very deep before hitting water in most of Orlando.

I reached into my pocket, grabbed my cell phone, and dialed the number that Margo recited to me. The phone rang once, twice, and then a groggy male voice answered, “Hello?”

“Mr. Arrington?” I asked. Margo wanted me to call because no one would ever recognize my voice.

“Who is this? God, what time is it?”

“Sir, I think you should know that your daughter is currently having sex with Jason Worthington in your basement.” And then I hung up. Part Two: accompli.

Margo and I threw open the doors of the minivan and charged down the street, diving onto our stomachs just behind the hedge ringing Becca’s yard. Margo handed me the camera, and I watched as an upstairs bedroom light came on, and then a stairway light, and then the kitchen light. And finally, the stairway down to the basement.
