Colton's Secret Investigation

As she digs into her history

Her own future hangs in the balance

Deputy Daria Bloom is conducting a covert investigation into her past. At the same time, she and FBI agent Stefan Roberts are closing in on the deadly Avalanche Killer. When sparks fly between Daria and Stefan, their mutual attraction soon complicates their manhunt. With two cases to crack, Daria must find her own killer truths within.

JUSTINE DAVIS lives on Puget Sound in Washington State, watching big ships and the occasional submarine go by and sharing the neighbourhood with assorted wildlife, including a pair of bald eagles, deer, a bear or two and a tailless raccoon. In the few hours when she’s not planning, plotting or writing her next book, her favourite things are photography, knitting her way through a huge yarn stash and driving her restored 1967 Corvette roadster—top down, of course.

About the Publisher

Chapter 1

She’d only capped off a few rounds, but Deputy Daria Bloom already knew her range score was going to suck. But she kept firing.

Fire.

A new missing girl.

Fire.

Bodies. Too many.

Fire.

Idiot media nicknames for monsters.

Fire.

Blue Eyes.

Fire.

Deputy Gates.

Fire.

Her mother.

Fire.

Stefan.

Fire. Fire. Fire.

She set down the Glock 19, still undecided whether the purchase had been worth it. She preferred her Springfield XD(M) because it fit her hands better. Her boss cut her some slack and let her carry the XD(M), since with it she was the best shot in the department. But the Glock was the official weapon of the sheriff’s office, and so she had to qualify with it, as well.

At the thought of her boss, she would have fired another round if she hadn’t already emptied the magazine. What if Trey Colton lost the election that was less than a week away now? She couldn’t imagine working for someone else. Not to mention that if he didn’t win, it would be so egregiously unfair. He was the best sheriff this county had ever had. But there was a serial killer still on the loose nearly ten months after the first body had been found, and the outcry was mounting. And while it was hardly Trey’s fault, he was the public face of the department, so all the blowback hit him.

Daria pushed the button that brought the target silhouette back to her. She studied the pattern of holes. It wasn’t as bad as she’d feared, but it wasn’t pretty. She’d visited the ten ring a time or two, but otherwise she’d been wide and high. She smothered a sigh.

For a moment she went through the postshooting routine, focusing on every step as if she’d never done it before. She knew she was trying to stop thinking about everything that had crowded into her mind, throwing off her concentration. Her frustration about this case was uppermost, but a certain FBI agent was nearing the top of the list, as well.

And to think she’d been pleased when Trey had selected her to be the local liaison with the Bureau. But that was before she’d laid eyes on Stefan Roberts. In all his tall, broad-shouldered, hard-muscled glory. She’d never really thought of herself as a woman who would go for a younger man, but that guy would give any breathing woman pause. In a twisted sort of way that made her not particularly happy with herself, she was glad his domestic situation was a mess, because it had enabled her to get over the initial shock of this gorgeous creature and put him where he belonged.

In the “not interested in” category.

And yet in the three months they had been collaborating together, the man had turned her carefully controlled life upside down. He was as fiercely dedicated to this case as she was, and that made working with him easier than it could have been. He had also done what she’d been trying unsuccessfully to do for years—he’d unraveled the sad conclusion to her mother’s story. She now had the history of Ava Bloom and knew the bravery her mother had shown. Thanks to Stefan.

He had done it as a favor to her. Without hesitation. And she couldn’t describe how that had made her feel.

“Well, you qualified, but barely.”

“I’m not done yet,” Daria told the range master, who had appeared behind her. The man smiled at her. For a rather crusty old guy, Ray Ingersol could be nice sometimes.

“And with those words, wars are won,” he said.

She smiled back at that. “I feel as if I’m in a war,” she admitted.

“Awful stuff going on. Awful stuff.”

She couldn’t argue that. With a fresh target and a new magazine, she shut everything else out of her mind and imagined having this ruthless Avalanche Killer in her sights. And this time when the target came back, there were four holes in the ten ring—three small individual holes, and one big ragged one.

Ray gave a low whistle. “Eight through the same hole? That’s some fine shooting, Deputy Bloom. I’m guessing you’ll be wanting that one turned in as your qualifying score?”

“Turn them both in,” she said as she gathered up her brass.

Ray’s smile widened, and he gave her an approving nod. “Honesty. I like that. It’s in short supply these days.”

“Sadly true.”

“Any closer on finding that maniac?”

“I think the official phrase is ‘the investigation is ongoing.’”

Ray snorted inelegantly.

“My sentiments exactly,” she agreed.

And she meant it. This case was beyond frustrating, for so many reasons. The obvious, of course—a deranged serial killer was destroying a town, both emotionally and economically, and here she was nearly a year later with no resolution—but also she felt as if she was letting Trey down. The sheriff had trusted her to get the job done when he’d had to recuse himself because the first suspect’s body had been found on his cousin Wyatt’s ranch, and there’d been an uproar about the Coltons getting preferential treatment. Which only made the load heavier, given her own personal history—which she had kept secret.

And then there was her gut certainty that Sabrina Gilford had not been a victim of their serial killer, which was just the cherry on top of this swirling mix. It was enough to give her nightmares, and in fact on occasion had.

Straighten up, girl—you didn’t get to where you are by quitting. Whoever, wherever this killer is, he’s going down, and you’re going to do it.

If he hadn’t gone for the shaved head look some time ago, Stefan Roberts figured he’d be tearing his hair out about now.

“I won’t go! I don’t like it here. I don’t like you!”

He stared at the five-year-old who was his son, standing there glaring at him with his arms crossed firmly across his small chest. He weighed his options. He could spend some more time trying to talk the child into going to school without a fuss. Except he was already running late for work. He could leave it for Mrs. Crane, the sitter he’d hired, to handle. But that seemed…cowardly somehow. He could pick the kid up and carry him out to the car. And maybe stuff him in the trunk? That’d go over well.

He sucked in a deep breath and fought for calm. Blowing up at his son would do no good at all, he was sure. He’d snapped at him a few times when he’d hit the end of his patience, and the boy had just closed off further.

“Look, Samuel, I know this wasn’t your idea. You didn’t want this. But we’re here—we’re stuck with each other. Can’t you make the best of it?”

The glare only intensified. So once more, he’d apparently said the wrong thing. And his already frayed temper lost another thread. When he spoke it was with the rigidness of an anger barely held at bay.

“That’s enough. You’re going to school, Samuel. How you go is up to you.”

Something shifted in the boy’s dark eyes, so like his mother’s. Something that was there and gone so quickly it was hard to pin a name on it. Had he been at work, he would have immediately registered it as fear, but he didn’t want to believe his son was afraid of him. The massive changes in his life, sure. But him? He didn’t like that idea at all.

But right now, he just had to get the boy out the door and to school. Mrs. Crane would see to him when school was out. He would have to talk to her, see if she had any ideas on how to deal with the rotten attitude Samuel seemed to have arrived with. But he didn’t have time now. He had to get to work. Daria would be wondering where the hell he was. And he didn’t want Daria Bloom mad at him.

Might be safer if she was.

He barely acknowledged the wayward thought. He was used to them by now. That day three months ago when he’d first walked into the sheriff’s office and seen the deputy assigned to the case, he’d known this wasn’t going to be routine. Working every day, in close proximity, to that? He’d known the first moment she turned those wide, beautiful, golden-brown eyes on him assessingly that this woman could be trouble. There wasn’t a damned thing about her he didn’t like, from the way that short, sleek haircut of hers bared the nape of her neck when she bent her head, to the way she moved, like a dancer he’d seen once back in Chicago.

Then again, he’d learned his lesson well; he’d been hot for Leah, too, and look how that had turned out. She hadn’t had whatever it took to be married to an FBI agent, if that even existed. She’d been excited at first, but then the reality of long hours away and the stringent dedication that the job necessitated had settled in. When she’d gotten pregnant with Samuel, things had improved a little, but it hadn’t lasted. By then she had bigger, grander plans for her future than being married to him.

And then it had fallen apart, and the son he loved so much had become a part-time presence in his life. He hated the fact, but between his work hours, Leah’s lack of cooperation, and then his transfer, that’s what had happened.

He shook off the thoughts; he needed to focus on the immediate issue, which was getting Samuel to school. In the end it took bribery—the promise of an extra bit of video-game time—but Stefan counted it as a win. At least the kid’s favorite game was a fantasy instead of just blowing stuff up or shooting people. And as he finally headed off to work, he found himself smiling wryly that that was the most optimistic thing he could think of just now.

He called the field office to check in. It was a formality, since he’d been allocated to this case full-time until it was resolved. When he got to the sheriff’s office and found Daria had not yet arrived, he felt a tiny bit of annoyance mixed with relief.

“She’s at the range,” the perky secretary they’d been assigned told him. Then, in a tone of confidentiality, she added, “She’s the best shot in the department, you know. Some of the guys won’t admit that, but she’s outscored all of them at one time or another.”

“Good to know,” Stefan said drolly. “I’ll try not to make her shooting mad at me.” He was only half kidding. There was something about Daria Bloom that made him think she was not a woman to be crossed.

“Oh, she’d never shoot at you. That’d be like shooting at one of the local scenic wonders.”

Stefan blinked. Was she flirting with him? She was, what, maybe twenty? He suddenly felt old.

“Now you’re a scenic wonder?”

He nearly groaned aloud as the voice came from behind him. A voice he recognized too well, since the husky timbre of it sent the craziest tingle over his skin. But he put on his best unaffected grin as he turned to see the woman in question approaching.

“So’s Denver International,” he said, referring to the jaw-dropping airport structure voted the ugliest building in the state by half the population, the most beautiful by the other half. And to his inward delight, she laughed. It was rare enough with all the pressure on her right now that she even smiled, so he counted this as a win.

“Sorry I’m late. I needed to clean both weapons, so it took longer.”

“Gotta keep the tools clean,” he agreed. “I was running behind myself.”

“Problem?”

“Only personal,” he said with a slight grimace. She let it go without asking, and he appreciated that. He appreciated a lot about Daria.

She confirmed with the secretary, who was watching them with a little too much interest, that there were no messages she hadn’t already gotten. They were turning to go to the office assigned solely to this case when the door behind them opened and Sheriff Trey Colton stepped through.

Trey was about Stefan’s own height and had a no-nonsense air about him that Stefan liked. He was also, as far as Stefan could see, a fine sheriff. By the book and honorable and, up until this Avalanche Killer mess, nothing had happened to mar his stellar record. As the first African American to be elected sheriff, not to mention one of the youngest people ever to hold the office, he was clearly determined to keep it that way. And Stefan was glad to help. He’d had his own dragons to slay on his way to where he was now, so he could relate.

They gave him an update, not that there was much to report. Trey restated his complete faith in them, which made Stefan even more determined, and with a barely concealed grimace the sheriff went off to deal with today’s round of media chaos.

Better him than me.

“He’s actually much happier lately,” Daria murmured as they said goodbye and headed down the hall.

“No thanks to us,” Stefan muttered.

“I know. Or the election campaign,” she added.

“I registered just so I could vote for him.” He’d only been in Colorado for a couple of years, so there hadn’t been a major election since his arrival.

“That’s good of you,” she said, sounding like she meant it.

“He’s a good guy. I admire and respect him and the job he’s done. And I’m glad if he’s happier.”

“Thank Aisha for that,” Daria confided as they went into what they’d begun to call the Avalanche office. “Now that’s a true love match.”

“Not something I’d know much about,” he grumbled, then regretted letting the words out.

“It’s pretty obvious with them, isn’t it? Besides, I happen to know she’s loved him for years.”

“She has?”

“Since they were kids in grade school.”

Stefan’s brow furrowed. “But they’re only getting together now?” The couple had become engaged about the time he and Daria had begun to work together on this case.

“She didn’t think he loved her, and she wasn’t going to settle for less. So she made him prove he meant it. He had to make the first move.”

She said it so approvingly even he couldn’t miss it. “Obviously you agree with that.”

“Yes. Completely. She had to be sure he felt the same.”

He studied her for a moment. Told himself it not only wasn’t his business, he didn’t want to know. Because knowing more about this woman had so far only drawn him in deeper, and that spelled trouble. But the next thing he knew he was asking, anyway.

“Personal experience?” She gave him a sharp look. He put up his hands and remembered his earlier thought that this was not a woman to be crossed. “You just sounded so…positive.”

Her expression changed to something more…he wasn’t sure what. Damn, Daria was hard to figure out. “You really want to open those doors, mine and yours?”

Well, that was plain enough; if she talked about her past, she was going to ask about his. Fine with him—the bare bones of his situation were common enough, and he had it down to a sound bite. “Mine’s easy. Married, she couldn’t handle my job, divorced.”

“I notice you left out the most important part.”

He grimaced, wishing he’d never started this. “Love? I thought so. Not sure about her.”

She studied him for a long moment before she said softly, “I meant your son.”

He was glad his skin was dark enough she couldn’t see what would be, judging from the heat he felt, a flaming blush. He couldn’t remember the last time he’d blushed. Maybe in the academy over a decade ago, when he’d missed a clue so obvious he’d felt humiliated.

“Yeah,” he muttered. “Never mind. You’re right. Don’t open those doors.”

Chapter 2

Unlike at the shooting range, there was only one reason Daria was having trouble focusing on the matter at hand right now, and his name was Stefan Roberts. He’d clammed up completely the moment she’d mentioned his son. And that bothered her.

She knew Stefan’s son had just recently come to live with him full-time, but other than that he never spoke of young Samuel other than to say they’d had very little contact since the divorce and what there had been hadn’t gone well. Most parents she knew were happy to talk endlessly about their kids. Her friend Fiona, with three boys, could go on forever. Yet Stefan never mentioned doing anything with the boy, or his interests, or even his existence. So she sensed things were not going well on that front.

As if this case isn’t enough of a distraction, imagine trying to deal with it with a five-year-old at home.

She resolved to cut him some slack as they dived back into the case.

“This room,” he said rather sourly as they closed the door on the office, “is starting to look like the lair of a lunatic.”

She looked around at the whiteboards they’d wheeled in, covered now with photographs and names and locations and details, with a single, long timeline spanning them all. Those had been Stefan’s idea—he said he’d always been able to work better with as much of the case as possible right in front of him all the time. She’d found it worked well for her, too.

“I can’t argue that,” she agreed. Nor could she argue the fact that his deep, rumbly voice did crazy things to her insides. Which made no sense at all.

“Worked a serial killer case in Rockford once. He had a room in his house that looked a lot like this. Only thing missing is the spiderweb of string he had pinned up, making up his elaborate conspiracy connections.”
