Unfortunately for Nic, her classmates aren't laughing, and humiliation finds her like a frigid draft. After ten weeks with cops she should now count as comrades and friends, she is still Nic the Hick from Zachary, Louisiana, a town of twelve thousand, where, until recently, murder was an almost unheard-of atrocity. It was not unusual for Zachary to go for years without one.

Most of Nic's classmates are so jaded by working homicides that they have come up with their own categories for them: real murders, misdemeanor murders, even urban renewal. Nic doesn't have her own pet categories. Murder is murder. So far in her eight-year career, she has worked only two, both of them domestic shootings. It was awful the first day of class when an instructor went from one cop to another, asking how many homicides each of their departments averaged a year. None, Nic said. Then he asked the size of each cop's department. Thirty-five, Nic said. Or smaller than my eighth-grade class, as one of her new classmates put it. From the beginning of what was supposed to be the greatest opportunity of her life, Nic quit trying to fit in, accepting that in the police way of defining the universe, she was a them, not an us.

Her rather whimsical maggot mischief, she realizes with regret, was a breach of something (she's not sure what), but without a doubt she should never have decided to give a gift, serious or otherwise, to the legendary forensic pathologist Dr. Kay Scarpetta. Nic's face heats up, and a cold sweat dampens her armpits as she watches for her hero's reaction, unable to read it, probably because Nic is stunned stupid by insecurity and embarrassment.

"So I'll call her Maggie, although we really can't determine gender yet," Scarpetta decides, her wire-rim glasses reflecting shifting candlelight. "But a good enough name for a maggot, I think." A ceiling fan snaps and whips the candle flame inside its glass globe as she holds up the vial. "Who's going to tell me which instar Maggie is? What life stage was she in before someone"-she scans the faces at the table, pausing on Nic's again-"dropped her in this little bottle of ethanol? And by the way, I suspect Maggie aspirated and drowned. Maggots need air the same way we do."
