Chapter 6 - The Canvas in the Attic

The ladder creaked under Carol’s weight as she climbed into the cramped attic. Dust motes swirled in the beam of Tessa’s flashlight, illuminating old fruit jars, iron bedsteads, and stacks of yellowed newspapers from the Vietnam War era.
Tucked between two oak roof joists, wrapped in heavy, tar-treated oilcloth and bound with thick jute twine, lay a rectangular parcel roughly four feet wide.
Carol lowered it down to Tessa, then climbed down into the warmth of the kitchen.
With a paring knife, Carol sliced the twine. She peeled away three layers of oilcloth, revealing a heavy linen canvas mounted on a hand-planed pine stretcher.
Tessa gasped.
The painting depicted Carol at twenty-three. She was standing waist-deep in the silver waters of the Red River gorge at twilight. Her dark hair was dripping wet, plastered against her shoulder, and she was smiling back at the viewer with an expression of raw, unvarnished intimacy.
Behind her, the limestone bluffs rose like ancient cathedrals, painted with thick, deliberate strokes of ultramarine, burnt umber, and a peculiar, luminescent violet that seemed to vibrate under the electric light.
"Good God," Tessa whispered, dropping to her knees. "The light... it’s Fontaine’s light. Exactly."
"No," Carol corrected gently. "It is Samuel’s light."
"Look at the pigment," Tessa said, leaning in so close her nose almost brushed the dried impasto. "Arthur Fontaine was world-famous for that specific violet-gray tone in his twilight skies. Art historians called it the 'Fontaine Lavender.' Critics wrote hundreds of essays trying to decode how he achieved that resonance. They thought it was an antique Venetian formula."
Carol gave a dry, soft laugh. "Samuel couldn't afford imported cobalt. He ground his own pigments. He took dried pokeberries from the hillside, boiled them with walnut oil, and mixed them with zinc white and powdered slate from the old quarry down by the tracks. He called it 'Hollow Violet.'"
Tessa’s hands shook as she grabbed her smartphone and dialed a number.
"Who are you calling?" Carol asked.
"Dr. Julian Thorne," Tessa replied, waiting as the line rang. "He’s the chief conservator and forensic chemist at the National Art Institute in Chicago. He’s also my former professor. If anyone can prove what this canvas is made of, it's Julian."
The call connected. "Julian? It’s Tessa. I need you on a charter flight to Kentucky tonight. Don't ask questions. Just pack your portable X-ray spectrometer and a mass-spectrometry kit."
"Tessa, it's eleven at night," a raspy, academic voice responded over the speaker. "I have a lecture at eight tomorrow morning."
"Julian, do you remember your monograph on the Fontaine twilight palette? The one where you argued that Fontaine used a synthetic resin invented in Lyon?"
A long silence followed on the other end of the line. "Of course I remember. It’s the cornerstone of Fontaine authentication."
"You were wrong," Tessa said. "Fontaine wasn't French. And the lavender isn't synthetic. It’s Kentucky pokeberry and pulverized slate. And I'm looking at the mother canvas right now."
Another heartbeat of absolute silence.

"Send me the landing coordinates," Dr. Thorne said. "I’ll be there before dawn."
