WAKING TO THE TUESDAY MORNING WEATHER REPORT, I KNEW I was in for killer cold. Not the occasional mid-forties damp we whine about in January in North Carolina. I mean subzero cold. Arctic cold. If-I-stop-moving-I’ll-die-and-be-eaten-by-wolves cold.

I adore Montreal. I love the not-quite-eight-hundred-foot mountain, the old port, Little Italy, Chinatown, the Gay Village, the steel and glass skyscrapers of Centre-ville, the tangled neighborhoods with their alleys and gray stones and impossible staircases.

Montreal is a schizoid scrapper, continually fighting with herself. Anglophone-Francophone. Separatist-Federalist. Catholic-Protestant. Old-New. I find it fascinating. I delight in the whole empanada, falafel, poutine, Kong Pao multiculturalism of the place. Hurley’s Irish Pub. Katsura. L’Express. Fairmont Bagel. Trattoria Trestevere.

I partake in the city’s never-ending round of festivals: Le Festival International de Jazz, Les Fêtes Gourmandes Internationales, Le Festival des Films du Monde, the bug-tasting festival at the Insectarium. I frequent the stores on Ste-Catherine, the outdoor markets at Jean-Talon and Atwater, the antique shops along Notre-Dame. I visit the museums, picnic in the parks, bike the paths along the Lachine Canal. I relish it all.

I do not relish the climate from November to May.

I admit it. I have lived too long in the South. I hate feeling chilled. I have no patience with snow and ice. Keep your boots and Chap-Stick and ice hotels. Give me shorts and sandals and a thirty-blocker.

My cat, Birdie, shares this view. When I sat up he rose, arched, then tunneled back under the covers. Smiling, I watched his body compact into a tight round lump. Birdie. My sole and loyal roommate.

“I’m with you, Bird,” I said, offing the clock radio.

The lump curled tighter.

I looked at the digits. Five-thirty.

I looked at the window. Pitch-black.

I bolted for the bathroom.

Twenty minutes later I was at my kitchen table, coffee at my elbow, Pétit file spread before me.

Marie-Reine Pétit was a forty-two-year-old mother of three who worked at a boulangerie selling bread. Two years earlier she’d gone missing. Four months later Marie-Reine’s decomposed torso had been discovered in a hockey bag in a storage shed behind the Pétit home. Marie-Reine’s head and limbs had been stashed nearby in matching luggage.

A search of the Pétit basement uncovered coping, hack, and carpenter’s saws. I had analyzed the cut marks on Marie-Reine’s bones to determine if a tool similar to one of hubby’s had made them. Bingo on the hacksaw. Rejean Pétit was now on trial for the murder of his wife.

Two hours and three coffees later, I gathered my photos and papers and rechecked the subpoena.

De comparaître personnellement devant la Cour du Québec, chamber criminelle et penal, au Palais de Justice de Montréal, à 09:00 heures, le 3 décembre —

Hot diggety. Personally invited to testify. As personal as a summons to a tax audit. No RSVP necessary.

I noted the courtroom.

Zipping into boots and parka, I grabbed gloves, hat, and scarf, set the security alarm, and headed down to the garage. Birdie had yet to uncurl. Apparently my cat had enjoyed a predawn breakfast.

My old Mazda started on the first try. Good omen.

At the top of the ramp, I braked too quickly and swam crosswise into the lane like a kid on a Slip ’n Slide. Bad omen.

Rush hour. The streets were clogged, every vehicle spinning up slush. The early morning sun turned my salt-spattered windshield opaque. Though I applied my wipers and sprayers repeatedly, for stretches I found myself driving blind. Within blocks, I regretted not taking a taxi.

In the late sixteenth century a group of Laurentian Iroquois lived in a village they called Hochelaga, situated between a small mountain and a major river, just below the last stretch of serious rapids. In 1642, French missionaries and adventurers dropped in and stayed. The French called their outpost Ville-Marie.

Over the years, the residents of Ville-Marie prospered and built and paved. The village took on the name of the mountain behind it, Mont Real. The river was christened the St. Lawrence.

Hello, Europeans. Good-bye, First Nations.

Today the former Hochelaga–Ville-Marie turf is known as Vieux-Montréal. Tourists love it.

Stretching uphill from the river, Old Montreal oozes quaint. Gaslights. Horse-drawn carriages. Sidewalk vendors. Outdoor cafés. The solid stone buildings that were once home to colonists, stables, workshops, and warehouses now house museums, boutiques, galleries, and restaurants. The streets are narrow and cobbled.

And offer not a chance of parking.

Wishing, once again, I’d taken a taxi, I left the car in a pay lot, then hurried up boulevard St-Laurent to the Palais de Justice, located at 1 rue Notre-Dame est, on the northern perimeter of the historic district. Salt crunched underfoot. Breath froze on my scarf. Pigeons remained huddled when I passed, preferring collective body warmth to the safety of flight.

As I walked, I thought of the pizza basement skeletons. Would the bones really prove to be those of dead girls? I hoped not, but deep down I already knew.

I also thought of Marie-Reine Pétit, and felt sorrow for a life cut short by unspeakable malice. I wondered about the Pétit children. Father jailed for murdering mother. Could these kids ever recover, or were they irreparably damaged by the horror that had been thrust upon them?

Passing, I glanced at the McDonald’s franchise across St-Laurent from the Palais de Justice. The owners had made a stab at colonial. They’d lost the arches and thrown up blue awnings. It didn’t really work, but they had tried.

The designers of Montreal’s main courthouse didn’t bother with architectural harmony. The lower stories consist of an oblong box covered with vertical black bars overhanging a smaller, glass-fronted box beneath. The upper stories shoot skyward as a featureless monolith. The building blends with the neighborhood like a Hummer parked in an Amish colony.

I entered the Palais to a packed house. Old ladies in ankle-length furs. Gangsta teens in clothes big enough to accommodate armies. Men in suits. Black-robed attorneys and judges. Some waited. Others hurried. There seemed no in-between.

Winding among large planters and uprights bearing starburst lights, I crossed to a bank of elevators at the back of the lobby. Coffee smells drifted from the Café Vienne. Already wired, I considered but passed up a fourth cup.

Upstairs, the scene was similar, though tipped in favor of the waiting game. People sat on perforated red metal benches, leaned against walls, or stood conversing in hushed voices. A few conferred with counsel in small interrogation rooms lining the corridor. None looked happy.

I took a seat outside 4.01 and pulled the Pétit file from my briefcase. Ten minutes later Louise Cloutier emerged from the courtroom. With her long blonde hair and oversized glasses, the crown prosecutor looked about seventeen.

“You’ll be my first witness.” Cloutier’s face was tense.

“I’m ready,” I said.

“Your testimony is going to be critical.”

Cloutier’s fingers twisted and untwisted a paper clip. She’d wanted to meet the previous day, but the pizza basement caper had nixed that. Our late-night phone conversation hadn’t provided the degree of preparation she’d wanted. I tried to reassure her.

“I can’t tie the marks on the bones to Pétit’s specific hacksaw, but I can say firmly that they were made by an identical tool.”

Cloutier nodded. “Consistent with.”

“Consistent with,” I agreed.

“Your testimony is going to be key, because in his original statement Pétit claimed he never laid eyes on that saw. An analyst from your lab is going to testify that she removed the handle and found minute traces of blood in one of the screw grooves.” I knew all of this from the previous night’s discussion. Cloutier was verbalizing the case against Pétit as much for her sake as for mine.

“A DNA expert is going to testify that the blood is Pétit’s. That ties him to the saw.”

“And I tie the saw to the victim,” I said.

Cloutier nodded. “This judge is a real pisser about qualifying experts.”

“Aren’t they all?”

Cloutier flicked a nervous smile. “The bailiff will call you in about five minutes.”

It was closer to twenty.

The courtroom was standard, nondescript modern. Gray-textured walls. Gray-textured carpet. Gray-textured fabric on long bolted benches. The only color was at center stage, inside the gates separating the spectators from the official players. Attorneys’ chairs upholstered in red, yellow, and brown. The blue, red, and white of the Quebec and Canadian flags.

A dozen people occupied the public benches. Eyes followed as I walked up the center aisle and took the stand. The judge was ahead and to my left, the jury straight ahead, facing me. Monsieur Pétit was to my right.

I have testified many times. I have faced men and women accused of monstrous crimes. Murder. Rape. Torture. Dismemberment. I am always underwhelmed by the accused.

This time was no exception. Rejean Pétit looked ordinary. Timid, even. The man could have been my uncle Frank.

The clerk swore me in. Cloutier rose and began questioning me from the prosecutor’s table.

“Please state your full name.”

“Temperance Deasee Brennan.”

We spoke into microphones suspended from the ceiling, our voices the only sound in the room.

“What is your profession?”

“I am a forensic anthropologist.”

“How long have you practiced that profession?”

“Approximately twenty years.”

“Where do you practice that profession?”

“I am a full professor at the University of North Carolina at Charlotte. I am forensic anthropologist for the province of Quebec through the Laboratoire de Sciences Judiciaires et de Médecine Légale, in Montreal, and for the state of North Carolina through the Office of the Chief Medical Examiner, headquartered in Chapel Hill.”

“You are an American citizen?”

“Yes. I have a Canadian work permit. I split my time between Montreal and Charlotte.”

“Why is it that an American serves as forensic anthropologist for a Canadian province?”

“There is no Canadian citizen who is both board-certified in this field and fluent in French.”

“We’ll return to the question of board certification. Please describe your educational qualifications.”

“I hold a Bachelor of Arts degree in Anthropology from the American University in Washington, D.C. I hold MA and PhD degrees in Biological Anthropology from Northwestern University in Evanston, Illinois.”

Next followed an endless series of questions on my graduate studies, my thesis and doctoral topics, my research, my grants, my publications. Where? When? With whom? What journals? I thought she was going to ask the color of my panties the day I defended my dissertation.

“Have you authored any books, Dr. Brennan?”

I listed them.

“Do you belong to any professional associations?”

I listed them.

“Have you held office in any of those associations?”

I listed them.

“Are you certified by any regulatory body?”

“I am certified by the American Board of Forensic Anthropology.”

“Please tell the court what that means.”

I described the process of application, the examination, the ethics review, and explained the importance of certifying boards in assessing the competence of those offering themselves as experts.

“In addition to the medicolegal labs in Quebec and North Carolina, is there any other context in which you practice your profession?”

“I have worked for the United Nations, for the United States Military Central Identification Laboratory in Honolulu, Hawaii, as an instructor at the FBI Academy in Quantico, Virginia, and as an instructor at the Royal Canadian Mounted Police Training Academy in Ottawa, Ontario. I am a member of a United States National Disaster Mortuary Response Team. On occasion I consult for private clients.”

The jury sat motionless, either fascinated or comatose. Pétit’s lawyer was taking no notes.

“Please tell us, Dr. Brennan. What does a forensic anthropologist do?”

I spoke directly to the jury.

“Forensic anthropologists are specialists in the human skeleton. We are brought into cases, usually, though not always, by pathologists. Our expertise is sought when a normal autopsy, focusing on organs and soft tissue, either is not possible or is severely limited and the bones must be examined for answers to crucial questions.”

“What types of questions?”

“The questions usually focus on identity, manner of death, and postmortem mutilation or other damage.”

“How do you help with questions of identity?”

“By examining skeletal remains I am able to provide a biological profile, including the age, sex, race, and height of the deceased. In certain cases I am able to compare anatomical landmarks observed on an unknown individual with similar landmarks visible on the ante-mortem X-rays of a known individual.”

“Aren’t most identifications accomplished using fingerprints, dental records, or DNA?”

“Yes. But to utilize dental or medical information it is first necessary to narrow the number of possibles to the smallest ascertainable sample. With the anthropological profile, an investigating officer can review missing persons reports, come up with names, and obtain individual records for comparison with the data associated with the discovered remains. We often provide the first level of analysis of a completely unknown set of remains.”

“How do you help with questions concerning manner of death?”

“By analyzing fracture patterns, forensic anthropologists are able to reconstruct events that caused particular traumas.”

“What types of trauma do you typically examine, Dr. Brennan?”

“Gunshot. Sharp instrument. Blunt instrument. Strangulation. But again, let me emphasize that this expertise would be requested only in situations in which the body was compromised to the point that those questions cannot be answered through soft tissue and organ examination solely.”

“What do you mean by compromised?”

“A body that is decomposed, burned, mummified, skeletal—”

“Dismembered?”

“Yes.”

“Thank you.”

The jury had definitely perked up. Three stared wide-eyed. A woman in the back row held a hand to her mouth.

“Have you previously been qualified by the courts of Quebec Province and elsewhere to serve as an expert witness in criminal trials?”

“Yes. Many times.”

Cloutier turned to the judge.

“Your Honor, we tender Dr. Temperance Brennan as an expert in the field of forensic anthropology.”

The defense raised no objection.

We were off.

By mid-afternoon Cloutier had finished with me. As opposing counsel rose, I felt my stomach tighten.

Here comes rough water, I thought. Mischaracterization, incredulity, and general nastiness.

Pétit’s attorney was organized and civil.

And finished by five.

As things turned out, his cross-examination was nothing compared with the nastiness I would encounter in dealing with the pizza basement bones.
