Chapter 4 - The Core Sample

By the fourth day, the smell of blood had left the suite, replaced by the scent of ozone and the damp river wind that whistled through the high transoms.
Wren had refused the wheelchair Teague brought. Instead, she used a stout hickory cane that Cormac had produced from an antique umbrella stand in the foyer. Every step was an exercise in calculated friction: she planted the rubber tip, locked her knee, shifted her center of gravity four inches to the left, and dragged the wounded leg forward with a small, sharp hiss between her teeth.
Cormac had set up a drafting table for her in the corner of his library, beneath a north-facing window that looked down onto the slate roofs of the French Quarter. On the table lay three hundred pages of geological surveys, core-sample logs, and structural cross-sections of the new terminal at Port Fourchon.
Cormac stood behind her, close enough that she could smell the clean, dry soap he used and the faint tang of gun oil on his cuffs.
“Look here,” she said, her finger tracing a blue line across an elevation cross-section. Her nail was trimmed short, neat, the nail of an engineer who worked with mechanical pencils and slide rules. “The Delacroix group used slag-aggregate concrete for the underwater caissons. They told the maritime board it was marine-grade Portland cement with silica fume.”
“What does the slag do?” Cormac asked.
“It absorbs sulfur from the brackish water,” she explained, turning slightly to look at him. Her face was still too pale, the skin beneath her eyes bruised with exhaustion, but the dull glaze of shock was gone. In its place was a cold, sharp lucidity that Cormac found far more dangerous than her vulnerability. “Over thirty-six months, the chemical reaction causes ettringite formation. The concrete expands from within. It micro-fractures. It looks solid on the surface, but the core has the structural integrity of wet shortbread.”
“How long do we have before it shows?”
“It’s already showing,” Wren said, pulling a sheet of black-and-white high-resolution sonar imaging from beneath a stack of invoices. “Look at the base of Pier Seven. These vertical fissures aren't settling cracks. They’re tensile failures. If Julian Delacroix ties an eighty-thousand-ton container ship to those bitts during a four-knot current, the entire pier will shear off at the mud line and take the dockside gantry with it.”
Cormac looked at the image. His face was unreadable, the hard bone of his jaw set like an iron mold. “How much did he clear on the substitution?”
“Twelve million on the concrete alone,” Wren said. “Another six on the rebar. He laundered it through three dummy transport companies registered in Grand Isle. All three companies have contracts with your freight lines, Cormac.”
She looked up at him, her dark eyes steady. “He didn't just steal from the city. He used your logistics network to haul the substandard aggregate from the blast furnaces in Alabama. When that bridge fails, the federal investigators will find your bills of lading in the mud.”
Cormac did not blink. “I know.”
Wren froze. “You knew? Before I came to your office?”
“I knew the aggregate was moving through my terminal at Mobile,” Cormac said, his tone matter-of-fact. “I didn't know where he was dumping it. Julian told me it was ballast for the rail beds in Mississippi. He was using my licenses to bypass the port safety inspections.”
“He was setting you up to take the fall for the collapse,” she whispered, the realization settling into her chest with cold, heavy weight. “If Pier Seven went down, the Delacroix family would claim they bought the materials in good faith from Vale Logistics. You’d be facing twelve counts of corporate manslaughter and federal racketeering.”
“Which is why,” Cormac said, reaching past her to take the sonar map from her hand, his fingers brushing against hers, “you are not just an engineer paying off a sister’s bad checks, Miss Calloway. You are the structural defense of my entire operation.”
Wren looked at his fingers—broad, scarred across the knuckles, steady as iron. “I don’t work for the mob, Vale.”
“You work for the person who keeps your sister out of an incinerator,” Cormac said coldly. “Right now, that happens to be me.”
The heavy mahogany door swung open without a knock. Teague stood there, his coat unbuttoned, his right hand resting flat against the grip of the SIG Sauer holstered at his left rib.
“Cormac,” Teague said. “Julian Delacroix is downstairs. He brought four cars and the deputy director of the levee board. He says he wants to discuss a discrepancy in his concrete manifests.”
Wren’s breath caught. She instinctively reached for the drafting table, her fingers digging into the cedar frame to steady herself.
Cormac turned slowly. He did not look hurried. He reached into his pocket, pulled out the hand-sharpened pencil he had been carrying, and laid it precisely parallel to the edge of the drafting table.
“Stay here, Wren,” he said.
“He knows I’m here,” she said, her voice dropping. “If he brought the levee director, he knows the whistle has blown.”

“He suspects,” Cormac corrected. “In this city, suspicion is just a conversation over bourbon. Proof is what happens when someone doesn't come home.” He looked down at her, his eyes drifting for a fraction of a second to the white linen bandage beneath her trousers. “Don’t stand up. The sutures haven’t set.”
