They had one bit of good news: a possible DNA sample. No semen, but three pubic hairs with nubs. There was no way of knowing if they had degraded to the point where the DNA was unrecognizable, but it was at least something to work with. He told Sparks that Doug Cohn would send someone over to pick them up once he had them prepared for transportation.

He hoped Olivia’s ex-husband was the good guy she seemed to think he was and wouldn’t balk at rushing another set of tests. He couldn’t help but wonder what had happened to make him an ex-husband.

“Doc Sparks, were there any marks on her right forearm, like in the Benedict and Davidson cases?”

“There’s not enough left of the skin and muscle tissue to tell. The abrasions in the other cases were shallow. There’s just no way of knowing if the killer left the same marks on this victim. But I did confirm that her hair was cut. I’ll write that up in the report.”

“Thanks.”

As Doc Sparks cleaned up, Zack left the autopsy room. He didn’t find Olivia in the lobby. He ran a hand over his rough face and realized he’d neglected to shave this morning, a common occurrence, especially when he worked a difficult case.

He wished he could have said something more to Olivia to let her know that it was okay that she hadn’t stayed. The pain in her eyes was unmistakable, before she got herself under control. There was no way he could blame her for her reaction, yet Olivia had such a strong backbone he was surprised she hadn’t stood her ground just to prove to him that she was a tough cop.

That alone intrigued him. There was definitely more to Olivia St. Martin than a pretty face and sharp intellect.

Stop it, Zack. No sense trying to figure out Superagent. She made it perfectly clear with her body language that she didn’t want anyone to get close to her. But he had to admit she was growing on him. There was so much pent-up energy in that petite body of hers; she rippled with it. He doubted she even noticed the way she constantly tucked her hair behind her ears, pulled on her lobes, or fidgeted with the single ring on her right hand.

Where was she? He was a little worried. Not that she couldn’t take care of herself. He glanced at his watch. He’d give her five minutes, then try to find her. She could simply be in the ladies’ room.

Movement from the front of the building caught Zack’s attention, and he looked at the double glass doors that led outside. Olivia St. Martin opened one side and stepped through. She blinked, adjusting to the artificial light. Her skin was pale. Too pale. Her hand brushed against her ear, tucking her hair behind it, though immediately a few strands fell forward. As she saw him across the lobby, she straightened and steeled her jaw, her face losing the softness she’d entered with.

“I apologize for my unprofessional behavior,” Olivia said as she approached. “I shouldn’t have left.”

The feelings simmering beneath Olivia’s cool mask were almost tangible, but she fought to prevent him from seeing anything. Why did she feel the need to keep such tight control over her emotions? If he didn’t release his frustration at the gym every morning, he’d be a bear all day. The job was demanding; you took release where you could get it.

“I told you I understood. You don’t have to put on a tough-girl act for me.” He paused, awkward. “I’ve known strong men to break down at the sight of a child on that table.”

She sighed and attempted a smile, but avoided his comment completely when she asked, “Did the exam yield anything useful?”

“Pubic hair. Doc Sparks is preparing it to be transported. Do you think your ex-husband would rush another sample?” He tried to make light of it, but Olivia was in no mood for humor.

She turned her back to him and started toward the exit. “I’ll call Greg and tell him to expect it. Have Doug send it to the same place. We have time to overnight it, because even if we put it on a plane again it wouldn’t get there until late tonight.” She paused, glanced at him. “It’s the same guy, though.” It wasn’t a question.

“No doubt.” Zack frowned and followed her out the door. He technically wasn’t on duty until four, but he’d already put in dozens of overtime hours, half of which he hadn’t logged.

He caught up with her in three strides. “What happened on the case you worked? Where the wrong guy was put in prison?”

She jerked, almost imperceptibly, but Zack was watching her very closely. Definite sore spot with her.

“The police found blood evidence in his truck that tied him to the girl’s murder,” she said momentarily. “He lied about his alibi-said he was at a bar, but when that didn’t hold water he changed his story to being home alone sleeping off a day of drinking. He was convicted largely on circumstantial evidence, but the evidence coupled with his lies to police-it was an easy call for the jury.” She rounded the corner toward where he’d parked after picking her up from her hotel.

“And then?”

“He got an attorney who learned there was a DNA sample from the killer and had his compared, which proved he hadn’t…” She stopped talking but refused to look at him as she strode down the sidewalk. She cleared her throat. “He didn’t rape the victim.”

“And they let him out? Just like that?”

“The D.A. realized that their case was compromised by the new evidence. He may have been involved, but the remaining evidence was circumstantial. There was nothing that proved he killed her.”

“Why hadn’t the DNA been compared earlier? That’s standard procedure.”

“It’s an old case.”

Old case? How old? For at least the last ten years, longer in many places, DNA testing had been commonplace. Zack glanced at her profile as they crossed the street to where he’d parked his police-issue sedan. On the surface she looked young. He’d thought thirty or so when he first saw her. Soft, delicate skin, shiny hair, slender curvy frame. But now he noticed fine wrinkles around her eyes, a slight weariness to her expression. The way she held herself showed a maturity that most women never learned to possess. She must be older than he thought. Thirty-five? Older? Maybe the case was the first she’d worked on. She’d blown it, took it personally, was on a vendetta-

“You’re not going to play vigilante, are you? Trying to right some wrong you think you did with the evidence in that old case? Because I’m not going to sit back and let the Feds screw up this investigation. I want this guy. Bad. But I want him by the book. I don’t want the bastard to walk because of a tainted investigation.”

She abruptly stopped walking and turned to him, her hands fisted at her sides. Her entire body reverberated in restrained anger. “This murderer has eluded justice for more than thirty years; I will do nothing to jeopardize a conviction. No one wants this killer more than me, Detective Travis. I’m sorry you have a problem with the FBI, but don’t take it out on me!”

She stormed off, stopping only when she reached his car.

Oh, yeah. Something was definitely going on. And Zack would damn well find out what it was.

Olivia didn’t know what had gotten into her. She never lashed out in anger. But her entire body felt like a tightly wound coil, ready to spring, shooting her emotions in all directions.

It had to be seeing Jillian Reynolds on the table. Just for a moment, but it had unnerved her. She had thought-for a split second-it was Missy lying there. About to be cut open by the coroner.

Then talking to Miranda-lying to her best friend-and knowing she and Quinn were in town. Why’d the killer have to strike in Seattle? The one place she actually had friends? She wouldn’t be surprised if Miranda hadn’t believed her when she said she was fine. After all, she was the world’s worst liar. Even over the phone.

She hated the deception. She wanted to tell Zack the truth. But if she did, there was no way he’d let her be a part of the investigation. He might even call Rick Stockton and have her fired. It would be within his rights. She’d misrepresented herself, misrepresented her assignment, and if this precarious house of cards fell before they found the killer-
