CHAPTER FOURTEEN
By four o'clock they were back at the precinct, and Martin Cross's alibi was already coming together.
The conference organizer at the Hilton had emailed a sign-in sheet within twenty minutes of Vaughn's request. Cross's name appeared on the check-in log for Wednesday afternoon and on the attendance roster for three separate panels, including his own presentation on Thursday evening.
A colleague named Dr. Anita Forsberg, who taught military history at the University of Minnesota, confirmed by phone that she'd sat next to Cross during the Thursday evening session and had dinner with him afterward at the hotel restaurant, where they'd argued about Gatling gun deployment at Petersburg until nearly eleven.
She remembered the argument because Cross had been, in her words, characteristically insufferable about it.
Isla set the phone down on Vaughn's desk and sat back. Cross stared up at her from the screen, mid-gesture at the podium, his expression carrying the focused intensity of a man who was precisely where he most wanted to be in the world.
"He's clean," Vaughn said. She'd been watching over Isla's shoulder, arms crossed. "Ironclad. Unless he's got a twin nobody mentioned."
"He's clean for the second murder, and I'd bet a week's pay the first will hold the same way.
" Isla rubbed the bridge of her nose. The day's accumulated fatigue was settling behind her eyes—not the physical kind but the cognitive weight of leads examined and set aside, the grinding attrition of investigation when the answers kept being not here, not him, keep looking.
"But." Vaughn didn't frame it as a question. She'd picked up on the same thing Isla had—the space between Cross's innocence and his relevance.
"But his behavior is still suspicious," Isla said.
"The frequency of his visits. The territorial attitude toward the collection.
The fact that he knows the exhibit plan.
" She pulled up Cross's name on her notepad and circled it—not as a suspect, but as something adjacent.
"People like Cross have a gravity. They attract information and they attract other people with similar interests.
If someone is using the Armory's collection and exhibit plans to stage murders, Cross might know them.
Might have talked to them at a conference like the one he just attended.
Might have shared details about the building without realizing what he was sharing. "
Vaughn nodded slowly. "You're saying he could be a conduit. Not the killer, but a path to the killer."
"Or he could simply know something he doesn't know he knows.
Either way, I don't want to lose sight of him.
" Isla met Vaughn's eyes. "Can you put a tail on him?
Low-profile, just observation. Where he goes, who he meets, whether his visits to the Armory change in frequency or pattern now that the murders have happened. "
Vaughn was already reaching for her phone.
"I'll have someone on him by tomorrow morning.
We're stretched thin, but for this I'll make room.
" She paused, thumb hovering over the dial screen.
"I could not agree more, by the way. Something about him isn't right.
Not in a guilty way—in a knows-more-than-he-thinks way. "
"That's the dangerous kind," Isla said. "Because people who don't know what they know can't protect the information."
Vaughn made the call. Isla gathered her notes and the case files she'd been building all day—a growing architecture of names, timelines, and questions that were multiplying faster than answers.
The distribution list for the renovation plans ran to forty-three names.
Forty-three people who had seen, at some level of detail, which exhibit would go where in the building and which weapons from the collection would anchor each display.
Forty-three minus the ones they'd already cleared.
Minus Cross, who was clean but circled. The math was still too wide.
She needed a different angle. The locks, maybe.
Someone who could open antique brass mechanisms without leaving marks—that was a skill, a practiced one, and practiced skills left traces in a person's history.
Locksmiths. Antique restorers. Collectors who worked with period hardware.
She added it to the list of threads to pull and felt the list stretch further than the day could hold.
She drove to the hospital with the windows cracked despite the cold, letting the March air sharpen the edges of her thinking the way it always did.
The lake was visible from the road, low and gray, the surface barely moving under the heavy sky.
Somewhere along its shore, Robert Brune was still breathing free air.
The thought surfaced the way it always surfaced—sudden, uninvited, accompanied by the low burn behind her ribs that had become as constant as her heartbeat.
She let it come. She let it sit. Then she put it away, because she had made a promise to James and a deal with Kate and she was trying, genuinely trying, to honor both.
The hospital corridor on the third floor had become as familiar as her own apartment hallway—the particular shade of the linoleum, the bulletin board with its rotating flyers for support groups and visiting-hour reminders, the nurse's station where Helen looked up and nodded as Isla passed with the easy recognition of someone who had stopped being a visitor and become a fixture.
She pushed open the door to 314 and stopped.
James was sitting up. Not propped—sitting.
His back straight against the raised bed, no pillows wedged behind him for support, his own musculature doing the work for the first time since she'd been visiting.
He was wearing a flannel shirt over his hospital gown—his own shirt, the green and navy plaid she'd seen him wear at the office a dozen times—and the effect was so startling, so normal, that for a moment he looked like a man who happened to be sitting in a hospital bed rather than a patient who happened to be wearing real clothes.
His color was better. The grayish cast that had lingered even after he'd regained consciousness was gone, replaced by something warmer, closer to the weathered complexion she remembered from before.
His eyes tracked her as she came through the door with the focused sharpness she'd missed for weeks, the crinkles at the corners deepening as something that was almost a smile moved across his face.
"You look like a person," she said.
"I've been told I resemble one on occasion.
" His voice was still rough at the edges—the ventilator had done damage that would take time to fully heal—but the strength underneath was unmistakable.
He shifted position without wincing, which was new.
"Travis had me walking the full corridor today.
Twice. Stacey brought clothes. Emma's coming tomorrow.
" He said it all in the understated, declarative way he said everything—as though the facts spoke for themselves and commentary was unnecessary—but Isla could hear what lived beneath the words.
Progress. Real progress. A man climbing back toward himself.
She set the coffee on his table—Superior Street, still warm—and dropped into the vinyl chair. "Patel's still saying another week?"
"Patel's being conservative, which is her job.
I'm pushing for Monday discharge." He held up a hand before she could object.
"Outpatient. I'm not talking about coming back to work.
I'm talking about sleeping in my own bed and making my own coffee and not listening to that cart rattle past my door at six in the morning.
" He reached for the cup, and his hands were steady around it—both hands, including the right one with its old fishing scar, which hadn't trembled once since she'd walked in. "So. Tell me about your day."
She told him. Not the sanitized version she'd given Linden the psychologist, not the efficient case summary she'd give Kate in her daily check-in tonight.
The real version—the morning at the precinct with Vaughn's corkboard and its pinned photographs, the long afternoon of interviews that produced more absence than presence, Graves and his careful revelation about Cross, Cross himself in his museum-house with his indignation and his pressed khakis and his genuine inability to prioritize human life over historical provenance.
James listened the way James always listened—completely, without interruption, his blue eyes steady on her face while his mind assembled the information into the structures he'd been building for two decades.
He asked no questions until she finished.
Then he was quiet for a moment, turning the coffee cup between his hands the way he'd done the last time she'd told him about the case, watching the surface as though the answers might be floating in it.
"The weapons match the exhibits," he said.
"Exactly. Bayonet in the Civil War zone. Mace on the medieval level."
"And the exhibit plan was distributed to forty-three people."
"Forty-three that we know of. Could be more—copies get shared, plans get left on tables, emails get forwarded."
James nodded slowly. "But the lock skill narrows it.
And the building knowledge narrows it further.
This person isn't just reading plans—they're moving through the Armory in the dark, navigating construction debris, avoiding a security guard's rounds.
They know the space physically, not just on paper. "
"That's what's keeping me up." She caught herself and amended: "That's what I keep coming back to.
The killer has an intimate relationship with the building.
Not just the plans, not just the collection—the building itself.
The way it feels to walk through it. Where the shadows fall. Which floorboards creak."
James studied her. The almost-smile surfaced again, and with it something warmer. "You're good at this. You know that."
"I'm doing my job."
"You're doing it well. That's not the same thing." He set the coffee down and shifted in the bed, angling himself toward her with the deliberate care of a body still negotiating with its injuries. "So. The question. Why?"
Isla waited.
"Not how—you'll find the how. The locks, the access, the building knowledge. That's mechanical. Solvable." He held her gaze. "Why is someone killing people with historical weapons and matching the kills to exhibit plans? What does the Armory mean to them?"
It was the question she'd been circling all day without landing on, and hearing James articulate it—stripped of noise, reduced to its essential shape—sharpened something in her thinking. She leaned forward.
"The renovation," she said. "It has to be the renovation.
The Armory is being transformed from what it was into something new.
The weapons are being moved, cataloged, put behind new locks in new configurations.
The building is being opened up and redesigned.
If someone has an attachment to the Armory as it was—to the collection as it was arranged, to the building as it existed before the construction crews arrived—"
"Then the renovation isn't progress," James said. "It's desecration."
The word landed with weight. Isla turned it over.
A historical guardian, she thought. Not someone stealing the weapons—that would be simpler, more rational.
Someone staging the weapons. Putting them to use in the spaces they were destined for, as if to demonstrate what the building was really for.
What the weapons were really for. Not display. Not education. Their original purpose.
"They're trying to stop the renovation," Isla said.
"Or protest it. Or punish it. The construction worker, the designer—those aren't random victims. They're the people transforming the Armory.
Lane was building the new structure. Hartley was designing the new layout.
The killer is targeting the renovation itself, through the people making it happen. "
James nodded. "Which means anyone else connected to the project is a potential target. The rest of the crew. The project manager. City council members who approved it."
"And Cross." She thought of the man in his neat Victorian, surrounded by his artifacts and his outrage.
"Cross opposed the renovation's approach to the collection.
Publicly, vocally. If the killer shares that worldview—if they see the renovation as a threat to the Armory's historical integrity—Cross might be an ally in their mind.
Someone they'd watch. Someone they'd contact. "
"Or someone they'd target, if they decided Cross wasn't doing enough to stop it."
The thought chilled her. She'd put a tail on Cross to watch who he talked to. She might also be protecting him.
James's eyes were heavy again—the fatigue arriving on schedule, the body's insistence on rest despite the mind's protest. But he fought it for another moment, holding her gaze with the quiet intensity that had always made her feel, against all evidence and common sense, that things would eventually be all right.
"You'll get there," he said. "You and Vaughn. She sounds solid."
"She is. She's territorial, sharp, doesn't trust easily. Reminds me of someone."
The crinkles appeared at the corners of his eyes. "Can't imagine who."
She stood and collected the empty cup, feeling the day's weight settle across her shoulders—the interviews, the dead ends, the vast architecture of the case spreading before her. But underneath the weight was something else. Direction. The beginning of a shape.
"Get some rest," she told him.
"Isla." His voice caught her at the door.
She turned. James Sullivan, sitting upright in a hospital bed in his own flannel shirt, looking more like himself than he had in weeks.
"Be careful with this one. Someone who sees murder as historical reenactment—that's not rage.
That's ideology. And ideology doesn't stop on its own. "
"I know."
"I know you know. I'm saying it anyway."
She held his gaze for a beat—the unspoken thing between them, steady and warm and unnamed—and then she walked out into the corridor, past the nurse's station and the elevator and the lobby with its antiseptic smell, and out into the cold Duluth evening where the sky was already darkening and the lake was a black line against the last gray light.
She sat in her car and opened her notebook. At the top of a clean page she wrote: Who loves the Armory enough to kill for it?
Then she started the engine and drove home through the dark, the question sitting beside her like a passenger, waiting to be answered.
