Trace - Cornwell Patricia (серии книг читать онлайн бесплатно полностью txt) 📗
"Oh no, she didn't die of the flu, did she? Oh no. Oh no. My baby girl. She didn't die of the flu. They took her from me."
"Who's they?" he asks. "You think more than one person had something to do with this?" He steps into the room and the lady doctor takes the water from him.
She helps Mrs. Paulsson sip it slowly. "That's good. Drink slowly. Slow breaths. Try to calm down. Do you have someone who can come stay with you? I don't want you staying alone right now."
"Who's they?" Her voice rises as she repeats the policeman's question. "Who's they?" She tries to get up from the chair but her legs won't work. They don't seem to belong to her anymore. "I'll tell you who they are." Grief turns to rage, such a terrible rage that she is afraid of it. "Those people he invited over here. Them. You ask Frank who they are. He knows."

In the trace evidence lab, forensic scientist Junius Eise holds a tungsten filament in the flame of an alcohol lamp.
He prides himself that his favorite tool-making trick has been used by master microscopists for hundreds of years. That fact, among others, makes him a purist, a Renaissance man, a lover of science, history, beauty, and women. Gripping the short strand of stiff, fine wire with forceps, he watches the grayish metal quickly incandesce bright red and imagines that it is impassioned or enraged. He removes the wire from the flame and rolls the tip into sodium nitrite, oxidizing the tungsten and sharpening it. A dip in a petri dish of water, and the sharp-tipped wire cools with a quick hiss.
He screws the wire into a stainless-steel needle holder, knowing that taking time out to make a tool this time was procrastination. Taking time out to make a tool meant he could take himself out of service for a moment, focus on something else, briefly regain a sense of control. He peers into the binocular lenses of his microscope. Chaos and conundrums are right where he left them, only magnified fifty times.
"I don't understand this," he says to no one in particular.
Using his new tungsten tool, he manipulates paint and glass particles recovered from the body of a man who was crushed to death by his tractor a few hours ago. One would have to be brain damaged not to know that the chief medical examiner worries that the man's family is going to sue somebody, otherwise trace evidence would not be relevant in an accidental death, a careless one at that. The problem is, if you look, you might find something, and what Eise has found doesn't make sense. At times like this he remembers he is sixty-three, could have retired two years ago, and has repeatedly refused promotion to Trace Evidence Section Chief because there is no place he would rather be than inside a microscope. His idea of fulfillment is disconnected from wrestling with budgets and personnel problems, and his relationship with the chief medical examiner is the worst it has ever been.
In the polarized light of the microscope, he uses his new tungsten tool to manipulate paint and metal particles on a dry glass slide. They are mixed with other debris, some sort of dust that is gray-brown and strange, unlike anything he has seen before with one very significant exception. He saw this same sort of trace evidence two weeks ago in a completely unrelated case, and he assumes that the sudden, mysterious death of a fourteen-year-old girl is unrelated to the death of a tractor driver.
Eise scarcely blinks, his upper body tense. The chips of paint, about the size of dandruff, are red, white, and blue. They aren't automotive, not from a tractor, that's for sure, not that he would expect them to be automotive in the accidental death of a tractor driver named Theodore Whitby. The paint chips and the strange gray-brown dust were adhering to a gash on his face. Similar if not identical paint chips and a similar if not identical strange gray-brown dust were found on the inside of the fourteen-year-old girl's mouth, mainly on her tongue. The dust bothers Eise the most. It is a very odd dust. He has never seen dust like this dust. Its shape is irregular and crusty, like dried mud, but it isn't mud. This dust has fissures and blisters and smooth areas and thin transparent edges like the surface of a parched planet. Some particles have holes in them.
"What the hell is this?" he says. "I don't know what this is. How can this same weird stuff be in two cases? They can't be related. I don't know what's happened here."
He reaches for a pair of needle-tip tweezers and carefully removes several cotton fibers from the particles on the slide. Light passes through lenses and a congregation of magnified fibers look like snippets of bent white thread.
"You know how much 1 hate cotton swabs?" he asks the virtually empty laboratory. "You know what a pain in the ass cotton swabs are?" he asks the large angular area of black countertops, chemical hoods, work stations, and dozens of microscopes and all of the glass, metal, and chemical accoutrements that they demand.
Most of the lab's workers aren't at their work stations but are in other labs on this floor, preoccupied with atomic absorption, gas chromatography and mass spectroscopy, x-ray diffraction, the Fourier Transform Infrared Spectrophotometer, the scanning electron microscope or SEM/Energy Dispersive X-ray Spectrometer, and other instruments. In a world of endless backlogs and little money, scientists grab what they can, jumping onto instruments as if they are horses and riding the life out of them.
"Everybody knows how much you hate cotton swabs," remarks Kit Thompson, Else's nearest neighbor at the moment.
"I could make a giant quilt out of all the cotton fibers I've collected in my short life," he says.
"I wish you would. I've been waiting to see one of your giant quilts," she replies.
Else grips another fiber. They're not easy to catch. When he moves the tweezers or tungsten needle, just the slightest fan of air moves the fiber. He readjusts the focus and bumps down the magnification to 40x, sharpening his depth of focus. He barely breathes as he stares into the bright circle of light, trying to find the clues it holds. What law of physics dictates that when a disturbance of air dislodges a fiber, it moves away from you as if it is alive and on the lam? Why doesn't the fiber drift closer to captivity?
He backs off the objective lens several millimeters, and the tips of his needle-sharp tweezers hugely invade the field of view. The circle of light reminds him of a brightly lit circus ring, even after all he's been through. For an instant he sees trick elephants and clowns in a light so bright it hurts the eyes. He remembers sitting in wooden bleachers and watching big pink puffs of cotton candy float by. He gently grabs another cotton fiber and air-lifts it off the slide. He unceremoniously shakes it loose inside a small transparent plastic bag filled with other spidery cotton debris that most certainly is Q-tip-type contaminants and of no evidentiary value.
Dr. Marcus is the worst litterbug of all. What the hell is wrong with that man? Eise has sent him numerous memos insisting that his staff tape lift trace evidence whenever possible, and please, please, don't use cotton-tipped swabs because they have zillions of fibers that are lighter than angel kisses and get all tangled up with the evidence.
Like white Angora cat hair on black velvet pants, he wrote Dr. Marcus several months back. Like picking pepper out of your mashed potatoes. Like spooning the creamer back out of your coffee. And other lame analogies and exaggerations.
"Last week I sent him two rolls of low-tack tape," Eise is saying. "And another package of Post-its, reminding him that low-tack adhesives are perfect for pulling hairs and fibers off things because they don't break or distort them or shed cotton fibers all over the ranch. Or, not to mention, interfere with x-ray diffraction and other results. So we're not just being finicky when we sit here picking them out of a sample all the livelong day."
