Chapter 1

DR. KAY SCARPETTA moves the tiny glass vial close to candlelight, illuminating a maggot drifting in a poisonous bath of ethanol.

At a glance, she knows the exact stage of metamorphosis before the creamy carcass, no larger than a grain of rice, was preserved in a specimen vessel fitted with a black screw cap. Had the larva lived, it would have matured into a bluebottle Calliphora vicina, a blow fly. It might have laid its eggs in a dead human body's mouth or eyes, or in a living person's malodorous wounds.

"Thank you very much," Scarpetta says, looking around the table at the fourteen cops and crime-scene technicians of the National Forensic Academy's class of 2003. Her eyes linger on Nic Robillard's innocent face. "I don't know who collected this from a location best not to contemplate at the dinner table, and preserved it with me in mind . . . but . . ."

Blank looks and shrugs.

"I have to say that this is the first time I've been given a maggot as a gift."

No one claims responsibility, but if there is a fact Scarpetta has never doubted, it is a cop's ability to bluff and, when necessary, outright lie. Having noticed a tug at the corner of Nic Robillard's mouth before anyone else realized that a maggot had joined them at the dinner table, Scarpetta has a suspect in mind.

The light of the flame moves over the vial in Scarpetta's fingertips, her nails neatly filed short and square, her hand steady and elegant but strong from years of manipulating the unwilling dead and cutting through their stubborn tissue and bone.

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."
