“So what’s your opinion?”

“I think somebody they knew inside the building asked them to do it, and explained it away as a routine test procedure, like a war game or a secret mission, said there was no harm in it, and coached them through what would happen afterward in terms of the video and the questioning and the lie detector. I think that might give a person enough composure to pass the polygraph. If they were convinced they weren’t in the wrong and there would be no adverse consequences. If they were convinced they were really helping the department somehow.”

“Have you pursued that with them yet?”

Stuyvesant shook his head.

“That’ll be your job,” he said. “I’m not good at interrogation.”

Reacher said nothing.

He left as suddenly as he had arrived. Just upped and walked out of the room. The door swung shut behind him and left Reacher and Neagley and Froelich sitting together at the table in the bright light and the silence.

“You won’t be popular,” Froelich said. “Internal investigators never are.”

“I’m not interested in being popular,” Reacher said.

“I’ve already got a job,” Neagley said.

“Take some vacation time,” Reacher said. “Stick around, be unpopular with me.”

“Will I get paid?”

“I’m sure there’ll be a fee,” Froelich said.

Neagley shrugged. “OK, I guess my partners could see this as a prestige thing. You know, government work? I could go back to the hotel, make some calls, see if they can cope without me for a spell.”

“You want to get that dinner first?” Froelich asked.

Neagley shook her head. “No, I’ll eat in my room. You two get dinner.”

They wound their way back through the corridors to Froelich’s office and she called a driver for Neagley. Then she escorted her down to the garage and came back upstairs to find Reacher sitting quiet at her desk.

“Are you two having a relationship?” she asked.

“Who?”

“You and Neagley.”

“What kind of a question is that?”

“She was weird about dinner.”

He shook his head. “No, we’re not having a relationship.”

“Did you ever? You seem awful close.”

“Do we?”

“She obviously likes you, and you obviously like her. And she’s cute.”

He nodded. “I do like her. And she is cute. But we never had a relationship.”

“Why not?”

“Why not? It just never happened. You know what I mean?”

“I guess.”

“I’m not sure what it’s got to do with you, anyway. You’re my brother’s ex, not mine. I don’t even know your name.”

“M. E.,” she said.

“Martha Enid?” he said. “Mildred Eliza?”

“Let’s go,” she said. “Dinner, my place.”

“Your place?”

“Restaurants are impossible here on Sunday night. And I can’t afford them anyway. And I’ve still got some of Joe’s things. Maybe you should have them.”

She lived in a small warm row house in an unglamorous neighborhood across the Anacostia River near Bolling Air Force Base. It was one of those city homes where you close the drapes and concentrate on the inside. There was street parking and a wooden front door with a small foyer behind it that led directly into a living room. It was a comfortable space. Wood floors, a rug, old-fashioned furniture. A small television set with a big cable box wired to it. Some books on a shelf, a small music system with a yard of CDs propped against it. The heaters were turned up high so Reacher peeled off his black jacket and dumped it on the back of a chair.

“I don’t want it to be an insider,” Froelich said.

“Better that than a real outside threat.”

She nodded and moved toward the back of the room where an arch opened into an eat-in kitchen. She looked around, a little vague, like she was wondering what all the machines and cabinets were for.

“We could send out for Chinese food,” Reacher called.

She took off her jacket and folded it in half and laid it on a stool.

“Maybe we should,” she said.

She had a white blouse on and without the jacket it looked softer and more feminine. The kitchen was lit with regular bulbs turned low and they were kinder to her skin than the bright office halogen had been. He looked at her and saw what Joe must have seen, eight years previously. She found a take-out menu in a drawer and dialed a number and called in an order. Hot and sour soup and General Tso’s chicken, times two.

“That OK?” she asked.

“Don’t tell me,” he said. “It’s what Joe liked.”

“I’ve still got some of his things,” she said. “You should come see them.”

She walked ahead of him back to the foyer and up the stairs. There was a guest room at the front of the house. It had a deep closet with a single door. A light bulb came on automatically when she opened it. The closet was full of miscellaneous junk, but the hanging rail had a long line of suits and shirts still wrapped in the dry cleaner’s plastic. The plastic had turned a little yellow and brittle with age.

“These are his,” Froelich said.

“He left them here?” Reacher asked.

She touched the shoulder of one of the suits through the plastic.

“I figured he’d come back for them,” she said. “But he didn’t, the whole year. I guess he didn’t need them.”

“He must have had a lot of suits.”

“Couple dozen, I guess,” she said.

“How can a person have twenty-four suits?”

“He was a dresser,” she said. “You must remember that.”

He stood still. The way he remembered it, Joe had lived in one pair of shorts and one T-shirt. In the winters he wore khakis. When it was very cold he added a worn-out leather pilot’s jacket. That was it. At their mother’s funeral he wore a very formal black suit, which Reacher had assumed was rented. But maybe it wasn’t. Maybe working in Washington had changed his approach.

“You should have them,” Froelich said. “They’re your property, anyway. You were his next of kin, I guess.”

“I guess I was,” he said.

“There’s a box, too,” she said. “Stuff he left around and never came back for.”

He followed her gaze to the closet floor and saw a cardboard box sitting underneath the hanging rail. The flaps were folded over each other.

“Tell me about Molly Beth Gordon,” he said.

“What about her?”

“After they died I kind of inferred they’d had a thing going.”

She shook her head. “They were close. No doubt about that. But they worked together. She was his assistant. He wouldn’t date people in the office.”

“Why did you break up?” he asked.

The doorbell rang downstairs. It sounded loud in the Sunday hush.

“The food,” Froelich said.

They went down and ate together at the kitchen table, silently. It felt curiously intimate, but also distant. Like sitting next to a stranger on a long plane ride. You feel connected, but also not connected.

“You can stay here tonight,” she said. “If you like.”

“I didn’t check out of the hotel.”

She nodded. “So check out tomorrow. Then base yourself here.”

“What about Neagley?”

Silence for a beat.

“Her, too, if she wants. There’s another bedroom on the third floor.”

“OK,” he said.

They finished the meal and he put the containers in the trash and rinsed the plates. She set the dishwasher going. Then her phone rang. She stepped through to the living room to answer it. Talked for a long moment and then hung up and came back.

“That was Stuyvesant,” she said. “He’s giving you the formal go-ahead.”

He nodded. “So call Neagley and tell her to get her ass in gear.”

“Now?”

“Get a problem, solve a problem,” he said. “That’s my way. Tell her to be out front of the hotel in thirty minutes.”

“Where are you going to start?”

“With the video,” he said. “I want to watch the tapes again. And I want to meet with the guy who runs that part of the operation.”
