"Definitely not," James agreed. "Pritchard's final assessment recommended that Langford undergo anger management training and suggested he showed 'concerning patterns of antagonistic behavior and lack of interpersonal cooperation.' The union fought it, and ultimately nothing came of the recommendation. Langford kept his job, and Pritchard's evaluation was filed away."
A personality conflict. A confrontation in an evaluation room between a pipe fitter with a reputation for rudeness and a research scientist who believed he could identify defective people through biological measurements. The kind of encounter that might stick in someone's mind, especially if they were already cataloging people whose behavior suggested moral corruption.
"What about Linda Graves?" Isla asked, though she suspected she already knew the answer.
James pulled up another file, and Isla saw the connection immediately. Seven years ago, Dr. Samuel Pritchard had applied to become a foster parent through Duluth County Family Services. Linda Graves had been assigned to evaluate his application, conducting home visits and psychological assessments to determine his fitness to care for children.
The application had been rejected.
"Graves's notes are in the file," James said, scrolling through the documentation. "She recommended against approval, citing 'concerning ideological rigidity' and 'an unusually clinical approach to human relationships that raises questions about emotional availability.' She also noted that Pritchard seemedmore interested in studying child development than in actually nurturing children."
Isla read through the assessment, recognizing Linda Graves's clinical efficiency in every line. The evaluation was thorough but cold, detailing Pritchard's shortcomings with the kind of dispassionate precision that would have felt like judgment to anyone on the receiving end. Graves had essentially declared him unfit to care for children, and she'd done it with the same bureaucratic efficiency that had earned her complaints throughout her career.
"Two victims, two documented negative encounters with Dr. Samuel Pritchard," Isla said, standing and reaching for her coat. The pieces were clicking into place with uncomfortable clarity. "A research scientist who believes he can identify morally defective people through physiological measurements, who's had professional contact with city employees for years, who personally encountered both victims in situations where their worst qualities were on display."
"That's motive and opportunity," James said, already grabbing his own jacket. "But it's all circumstantial. We don't have anything that directly connects him to the murders. And we still don't know how he'd even know about the tunnel system, let alone be able to navigate it well enough to commit these crimes."
"Then we need to talk to him. See how he reacts when we bring up Langford and Graves. See if he knows they're dead." Isla checked her weapon, making sure the magazine was fully loaded. She was probably being paranoid—they were going to interview a research scientist at his home, not apprehend an armed fugitive—but after two murders in the steam tunnels, she wasn't taking chances.
James paused at the door. "You think he'll run?"
"I think if he's our killer, he's been planning this for a long time. He'll be prepared for questions. Prepared for suspicion."Isla met his eyes. "But he won't be expecting us to understand his ideology. That's our advantage—we can see the worldview that justifies the murders, and he'll think we're just looking for conventional motives."

They drove through Duluth's late-morning traffic in focused silence, Isla's mind running through interview strategies while James navigated toward the address they'd found in Pritchard's consulting records. The scientist lived in a renovated Victorian in the Congdon Park neighborhood, an area of elegant older homes occupied mostly by professionals and academics. The kind of place where neighbors minded their own business and nobody would notice if someone kept unusual hours or made regular trips to the industrial district at night.
The house was well-maintained, painted a deep blue with white trim and a wraparound porch that suggested someone with both money and aesthetic sensibility. Pritchard's vehicle—a silver Subaru Outback, practical and unremarkable—sat in the driveway. Through the front windows, Isla could see lights on inside.
"He's home," James said unnecessarily.
They approached the front door together, and Isla noted the security camera mounted discreetly near the porch light. Standard for this neighborhood, nothing unusual, but it meant Pritchard would see them coming. She pressed the doorbell, hearing chimes echo inside the house.
Footsteps approached, and then the door opened to reveal Dr. Samuel Pritchard in person.
He was tall—maybe six-one—but with a lean, almost fragile build that suggested age catching up with genetics. His hair was more salt than pepper, trimmed short and professional, and he wore wire-rimmed glasses that magnified intelligent gray eyes.He dressed like someone who worked from home—khakis and a button-down shirt, casual but put-together. His shoulders had the slight stoop of someone who spent long hours at a computer, and his handshake when he gestured them inside was cool but not particularly strong. Everything about his appearance suggested competence, rationality, the kind of person you'd trust to design monitoring systems for critical infrastructure—but not someone who looked capable of overpowering victims in dark tunnels.
"Dr. Pritchard?" Isla held up her FBI credentials. "Special Agent Isla Rivers, and this is Special Agent James Sullivan. We'd like to ask you a few questions about your consulting work with the city's personnel department."
Pritchard's expression shifted through surprise, concern, and then a kind of careful neutrality that made Isla's investigator instincts prickle. "Of course. Please, come in."
He stepped back, gesturing them into a foyer that opened onto a living room furnished with mid-century modern pieces and walls lined with bookshelves. The space was immaculate, everything precisely arranged, the kind of home that reflected its owner's need for control and order. Through an archway, Isla could see what looked like a home office, computer monitors glowing with data displays she couldn't read from this distance.
"Can I offer you coffee?" Pritchard asked, already moving toward what Isla assumed was the kitchen. "I just made a fresh pot."
"No, thank you," Isla said, though James accepted with the kind of casual friendliness that sometimes put interview subjects at ease. They followed Pritchard into a kitchen that was as precisely organized as the rest of the house—granite countertops clean and clear, appliances spotless, everything in its designated place.
Pritchard poured coffee for James and himself, and they settled around a dining table positioned to catch morning light from a large window overlooking a carefully tended backyard. Isla chose her seat strategically, positioning herself where she could see Pritchard's face clearly while James sat slightly to the side, the classic interrogation triangle.
As Pritchard lifted the coffee pot, Isla noticed the slight tremor in his hands—barely perceptible, but there. Age, perhaps, or nerves. Either way, it reinforced her initial impression: this man seemed too physically frail to have wrestled David Langford into scalding steam or held Linda Graves underwater until she drowned.
"So," Pritchard said, wrapping his hands around his coffee mug in a gesture that looked practiced and controlled. "What can I help you with, Agent Rivers?"
"We're investigating two recent deaths in the city," Isla said, watching his face carefully. "Both victims were found in the steam tunnel system. David Langford and Linda Graves. We understand you had professional encounters with both of them."
Pritchard's expression didn't change, but Isla caught the slight tension in his shoulders, the way his fingers tightened fractionally around the mug. "I heard about that on the news. David Langford, the city worker. Terrible thing. An accident, I assumed?"
"Not an accident," James said quietly. "Murder. And there's been a second victim—Linda Graves, a social worker with County Family Services."
