CHAPTER THIRTEEN #2
Martin Cross lived in a Victorian on East Third Street, maintained with the aggressive precision of a man who considered entropy a personal enemy.
The paint was crisp, the walkway edged, the small front garden dormant but clearly tended in season.
An historical marker on the porch railing indicated the house's 1892 construction date, which told Isla something about the occupant before he'd said a word.
Cross answered the door on the second knock.
He was mid-fifties, thin, sharp-featured, with wire-rimmed glasses and graying hair combed with a neatness that bordered on architectural.
He wore a button-down shirt tucked into pressed khakis despite it being a Friday afternoon, and he looked at their badges with the expression of a man who had been expecting this visit and resenting it in advance.
"I assumed someone would come," he said, stepping aside to let them in. "Though I'd have thought sooner."
The interior was a museum in miniature. Display shelves lined the hallway, filled with military artifacts—replica weapons, framed maps, regiment insignia behind glass.
The living room held more of the same, along with bookshelves packed with military history volumes organized by era, their spines aligned to the millimeter.
It was the home of a man whose passion had long ago crossed the line from hobby to identity.
Cross sat in a leather armchair and waited. He didn't offer coffee.
"Mr. Cross, we're investigating the deaths of Thomas Lane and Clara Hartley at the Armory," Vaughn began. "As a board member of the historical society with access to the building and the weapon collection, we need to ask you some questions."
"The weapons are the issue, aren't they?
" Cross leaned forward, and what animated his face wasn't nervousness—it was indignation.
"I've been saying for months that the collection wasn't being properly secured.
Months. I raised it at three consecutive board meetings.
The locks on those cases are original brass mechanisms from the 1890s—they're historically appropriate, which is why Margaret insisted on keeping them, but they're not adequate security for pieces of this significance.
And now two of them have been removed from their cases and used as—" He stopped.
His jaw tightened. "Those aren't murder weapons, Detective.
They're irreplaceable artifacts. An 1861 Springfield socket bayonet.
A fifteenth-century flanged mace, likely German, possibly Burgundian. The provenance alone—"
"Two people are dead," Isla said quietly.
Cross looked at her. Something flickered across his face—not guilt, she thought, but the discomfort of a man hearing his own priorities reflected back to him and recognizing the disparity.
"I'm aware of that. I'm not callous. But the destruction of historical artifacts in the commission of a crime is itself a tragedy, one that exists alongside the human one. "
It was an extraordinary thing to say, and he said it like he meant it entirely. Isla filed it away and watched him.
"Mr. Cross, where were you on the night of March twenty-seventh, between six and nine PM?"
The question landed and Cross received it with a stiffness that could have been offense or preparation.
"I was in Minneapolis. The Upper Midwest Military History Conference at the Hilton downtown.
I presented a paper on Civil War-era small arms manufacturing in Minnesota.
I left Duluth Wednesday morning and didn't return until this morning.
" He stood, crossed to a desk in the corner, and produced a conference program with his name printed in the schedule.
"I can provide the names of colleagues who attended my panel, as well as the hotel reservation if you need it. "
They took the information. They asked him about the renovation plans—who had seen them, who had copies.
Cross confirmed that the full plans, including exhibit designations by era, had been distributed to all board members, the construction company's project manager, the design team, and the city council's cultural affairs committee.
A wide net. Isla wrote down every name he gave and watched his hands as he spoke—steady, precise, the hands of a man who handled things carefully and expected others to do the same.
Outside, Vaughn sat behind the wheel and didn't start the car. She stared through the windshield at Cross's impeccable Victorian and said nothing for ten seconds, which was a long time for a woman who'd been talking at a detective's clip all day.
"My gut says no," Vaughn said.
Isla looked at her. It was the first purely instinctive statement Vaughn had made in her presence, and it cost the detective something to say it—Isla could see it in the way she gripped the steering wheel slightly tighter, as though bracing against her own admission.
"Mine too," Isla said.
They sat with that for a moment. Cross was the best lead they'd had all day.
He had access, knowledge, opportunity, and the kind of obsessive relationship with the collection that could, in the right psychological framework, tip into something darker.
But obsession alone wasn't motive, and the man Isla had just watched in that living room—indignant, precise, genuinely aggrieved about the weapons rather than the victims—didn't match the profile taking shape in her mind.
The Armory killer wasn't someone who revered the weapons.
They were someone who saw the weapons as tools for a purpose, means to an end that had nothing to do with historical preservation.
"We verify the alibi anyway," Isla said. "Conference attendance, hotel records, every hour accounted for."
"Obviously." Vaughn started the car. "But if Cross is clean, we're back to a distribution list the size of a phone book and no physical evidence linking anyone to either scene."
"Then we work the list." Isla looked out the window as Duluth scrolled past—the old houses, the lake glimpsed between buildings, the sky pressing down like something with weight.
"Someone on it knows that building well enough to walk through it in the dark, open antique locks without a scratch, and match weapons to exhibit plans that most people would need a blueprint to understand.
That's not a wide skill set, Detective. We narrow it. "
Vaughn glanced at her—a quick, evaluative look that held more warmth than anything she'd offered that morning. "Call me Sarah," she said. And drove.
