“Anything I can do?”

He shook his head. “Not right now. Carine’s gone up to Beanie’s already. Maybe this woman worked her way down to the lake, who knows. Let me grab my stuff and I’ll give you a ride up there.”

The original plan was for Mackenzie to meet Carine, a nature photographer, at her studio, and hang out there until Gus finished work and could take the baby. They would then head up to the lake. But Mackenzie didn’t mind going early. She waited for Gus outside, where the bright afternoon sun was baking the quiet village street of Cold Ridge, which was tucked in a bowl-shaped valley among the White Mountains.

Compared to Washington, the weather was warm and pleasant, but by northern New England standards, it was a hot afternoon. Mackenzie felt strange not having a car, but she’d flown into Manchester and caught a ride to Cold Ridge with another deputy marshal out of the New Hampshire district office. Driving from Washington would have eaten up too much of her weekend, and renting a car when she was saving up for a place of her own was out of the question. But not having her own transportation underscored her new role as a nonresident – an outsider.

Gus joined her, and they climbed into his truck and headed out of town, turning off onto a dirt road and finally pulling into the sloping driveway that led to Bernadette Peacham’s classic New Hampshire lake house. It was built close to the water, amid tall pines, oaks and sugar maples. Across the small, isolated lake, Mackenzie could see her parents’ house. She checked in with them once a week at their Irish cottage and had met the couple they’d swapped with a few times. She had no idea if Bernadette had met them, or if they’d seen Cal with his young brunette girlfriend. There were few houses on the lake. Bernadette owned much of the wooded shoreline, with no plans to develop any of it.

“Need a hand with anything?” Gus asked, coming to a stop behind Carine’s truck.

“No, thanks. I packed light.”

“You’re missed around here.” He gave her a grudging smile and added, “Deputy.”

She grinned at him. Of all the people who hadn’t believed she’d get through the vigorous training to become a federal agent, Gus Winter was at the top of the list. “Never going to get used to saying that, are you?”

He laughed. “Not a chance. So long as you’re happy -”

“I am,” she said, quickly grabbing her backpack from behind her seat. “Good luck finding your hiker. Did you want to talk to Carine?”

“No – she’d call if she ran into the hiker. I plan to be back in time to pick up the baby. You two just relax and have a good time.” He scrutinized Mackenzie for a moment. “You look stressed. When you were a college professor, you never looked stressed.”

“I did. You just never noticed.”

“Maybe because you weren’t carrying a gun.”

As soon as she climbed out of his truck, Gus took off. Mackenzie carried her backpack along a stone walk to the front of the house, its cedar shingles in need of a fresh coat of dark brown stain. Its shutters, a deep evergreen, were so nicked and scarred they probably should be replaced altogether. As with almost everything else in Bernadette Peacham’s life, money wasn’t the issue. She had ample funds to do whatever she wanted. Time, inclination and a tendency to overcommit were another matter.

The lake sparkled in the bright afternoon sun, and Mackenzie welcomed the cooler air, the familiar sights and sounds. She headed to the screen porch. A drop-leaf table she knew Bernadette meant to paint was there, in the same condition as when she’d brought it home from a yard sale two years ago. She often said that her life was so filled with deadlines, she appreciated having a project with no firm end date. She’d get to the table when she got to it.

The door into the kitchen was unlocked. Feeling herself begin to relax, Mackenzie found a note from Carine indicating she was off for a quick walk with Harry, her eight-month-old.

Which meant, as Gus had predicted, she was looking for any sign of the missing hiker.

Carine had left paper bags stuffed with groceries on the table, enough to feed two women for a week, never mind twenty-four hours. Mackenzie ripped open a package of marshmallows and popped one into her mouth as she headed down a short hall to a linen closet. In her haste to get out of Washington, she hadn’t packed a swimsuit, but the closet, overflowing with a mishmash of towels, facecloths, sheets and extra blankets, yielded a fuchsia two-piece tankini and a beach towel – pink dolphins against a turquoise background – from her pre-law-enforcement days.

She ducked into the bathroom, which, like the rest of the house, had changed little over the years. Bernadette fixed things at the lake as needed. She didn’t renovate.

Once she’d changed into the swimsuit, Mackenzie locked her 9 mm Browning in a small safe in the pantry. Then she headed back out to the porch and down to the water. She passed the shed her father had built for Bernadette, where the bloody accident that had almost killed him had occurred, and walked out onto the wooden dock. He’d been cutting wood for the new dock that day.

But she pushed the images back and stood at the end of the dock. Even in August, the lake would be cold.

With an ease that surprised her, Mackenzie dived in without hesitation, trusting herself to remember that the water off the dock was deep enough. She wouldn’t risk smashing her head on a rock or scraping a knee on the rough bottom of the lake.

She surfaced almost immediately, squinting up at the clouds as she took in a breath and tried to stay focused on her surroundings, the feel of the breeze on her wet face and hair.

Don’t think about Washington.

About Rook.

In a few moments, she adjusted to the cold water and flipped onto her back. The nearly cloudless sky was all she could see as she floated, going still, tilting her head back the same way she had as a girl, when the lake had been her refuge, and her keenly intelligent, eccentric neighbor had been her salvation in the tense, frantic months of her father’s long and uncertain recovery. He couldn’t return to the carpentry work he knew and loved. She’d later learned that money was tight. Her mother, who’d worked part-time as a teacher’s aide, had turned to full-time work, every ounce of her energy going to keeping food on the table and helping her husband get back on his feet.

Mackenzie dived again, remembering telling her parents not to worry about her, that she’d be fine. She’d always loved roaming the woods, catching frogs on the lakeshore, watching the loons. With her father needing so much of her mother’s attention, Mackenzie had figured her propensity to wander could finally be a help instead of an annoyance and a cause for concern. She’d relished her time alone in the woods.

Eventually, though, she’d decided to hitchhike into town, and Nate Winter, then a teenager, had picked her up and taken her to his uncle at his store, where she’d promptly stolen a jackknife and a couple of packs of waterproof matches.

Almost twenty years later, she couldn’t remember the emotion that had driven her to pocket things that weren’t hers, only the deep shame and anger – at herself, at everyone – when Gus had caught her.

And Bernadette’s talk. Mackenzie remembered that. The law, Bernadette had explained, wasn’t about seeing what you could get away with. Red lights weren’t to be obeyed just when a police car was in sight. They were there for the welfare and safety of everyone.

She’d never mentioned Mackenzie’s parents and how preoccupied and overwhelmed they were. In retrospect, Mackenzie understood that was why Gus had taken her to Bernadette and not them.

Blunt and straightforward, their neighbor had offered Mackenzie use of her library of books at the lake. She could take them home with her, or she could sit out on the porch or the dock and read to her heart’s content. When Bernadette was in Washington, she allowed Mackenzie to let herself into the lake house for a fresh supply of books.
