"Good sleuthing takes practice," he continued.

"So does sex," came another back-of-the-room comment. We all bit back laughter while Coach pointed a warning finger at the offender.

"That won't be part of tonight's homework." Coach turned his attention back to me. "Nora, you've been sitting beside Vee since the beginning of the year." I nodded but had a bad feeling about where this was going. "Both of you are on the school eZine together." Again I nodded. "I bet you know quite a bit about each other."

Vee kicked my leg under our table. I knew what she was thinking. That he had no idea how much we knew about each other. And I don't just mean the secrets we entomb in our diaries. Vee is my un-twin. She's green-eyed, minky blond, and a few pounds over curvy. I'm a smoky-eyed brunette with volumes of curly hair that holds its own against even the best flatiron. And I'm all legs, like a bar stool. But there is an invisible thread that ties us together; both of us swear that tie began long before birth. Both of us swear it will continue to hold for the rest of our lives.

Coach looked out at the class. "In fact, I'll bet each of you knows the person sitting beside you well enough. You picked the seats you did for a reason, right? Familiarity. Too bad the best sleuths avoid familiarity. It dulls the investigative instinct. Which is why, today, we're creating a new seating chart."

I opened my mouth to protest, but Vee beat me to it. "What the crap? It's April. As in, it's almost the end of the year. You can't pull this kind of stuff now."

Coach hinted at a smile. "I can pull this stuff clear up to the last day of the semester. And if you fail my class, you'll be right back here next year, where I'll be pulling this kind of stuff all over again."

Vee scowled at him. She is famous for that scowl. It's a look that does everything but audibly hiss. Apparently immune to it, Coach brought his whistle to his lips, and we got the idea.
