Amanda said, "Best guess."

"Well..." Charlie shrugged again. "It seems probable in the greater context of the scene that there was a struggle. What I can definitely tell you is that at some point, Adam was on his knees beside the body. We've got the blood pattern on his jeans as well as the tops of his shoes. I have a theory that he reached out"—Charlie stretched his arm out near the bloody handprint—"and leaned his hand against the wall as he put his ear to Kayla's mouth."

Will stopped him. "Why do you say that?"

"He's got a light spray of B-negative just around here." He indicated his own ear. "There's also that spray of O-negative on Kayla's abdomen, which you pointed out to me earlier. I'd draw the same conclusion as you—he removed the knife from his own chest while he was bending over her. In fact, we found a mixture of both blood types on the weapon."

"Any fingerprints?"

"Just one set. Preliminarily, we'll say they're Adam's, but they'll have to confirm that at the lab. There were also markings on the knife handle that look consistent with someone wearing latex gloves."

Amanda told Will, "Throw wearing surgical gloves in with him bringing the knife to the scene and we've got premeditated murder."

Will didn't point out that they would have to find the killer before they could charge him. "What about the footprint downstairs?"

"That's where it gets interesting," Charlie began. "Type O-positive."

Amanda said, "Different from the two victims."

"Exactly," Charlie confirmed. "We found several spots on the stairs, a couple more up here. My guess is that whoever the blood belongs to was unconscious. As Will and I suggested, she was carried down the stairs. Either the abductor had to stop at the bottom to reposition her or she came to and started to struggle. Somehow, her foot touched the ground at that one spot."

Will told Amanda, "I've asked Charlie to Lumenol the house top to bottom. I'm curious about where Emma Campano was while her friend was being attacked."

"It follows that she was unconscious somewhere."

"Not here," Charlie supplied. "At least, not by what the blood tells us."

Will said, "We've had a lot of mistakes made today. I want to make sure that footprint downstairs belongs to Emma Campano. She's got a ton of shoes in her closet. Maybe you can get a latent?"

"It's a long shot, but I can certainly try."

Amanda asked, "Did you find any sperm in this area?"

"Nothing."

"But Kayla Alexander had sperm on and in her person."

"Yes."

She told him, "I want a rush DNA comparison against both Adam Humphrey and Paul Campano. Check the master bathroom for hair or any tissue you can find that might belong to the father." She looked at Will, as if waiting for him to object. "I want to know who this girl has been having sex with, consensual or otherwise." She didn't wait for a response, turning on her heel after tossing a "Will?" over her shoulder.

He followed her down the back stairs and into the kitchen. Will tried to get ahead of her on the blame game. "Why didn't you tell me Faith Mitchell's mother was part of my investigation?"

She started opening and closing drawers. "I assumed you would use your brilliant detective skills to make a connection between the two last names."

She was right, but Evelyn Mitchell hadn't been a priority for him for a long time. "Mitchell is a common name."

"I'm glad we have that settled." Amanda found what she was looking for. She held up a kitchen knife, looked at the silver bee on the handle. "Laguiole. Nice."

"Amanda—"

She placed the knife back in the drawer. "Faith will be your partner going forward on this investigation. We've pissed off the Atlanta Police Department enough this year without pulling another major case from them, and I'd rather partner you with a goat than put Leo Donnelly on this."

"I don't want her."

"I don't care," she shot back. "Will, this is a major case I'm handing you. You're thirty-six years old now. You're never going to move up if—"

"We both know this is as far as I'm going to get." He didn't give her room to disagree. "I'm never going to do PowerPoint presentations or stand in front of a chalkboard filling in a timeline."

She pursed her lips, staring at him. He wondered why the disappointment in her eyes bothered him so much. As far as he knew, Amanda didn't have any children or even a family. She wore a wedding ring sometimes, but that seemed to be more for decoration than declaration. For all intents and purposes, she was as much an orphan as he was. Sometimes, he thought that she was like the dysfunctional, passive-aggressive mother he'd never had—a fact which made Will glad that he had grown up in the children's home.

She said, "It's dry erase now. You don't get chalk on your hands."

"Oh, well...sign me up."

She smiled ruefully. "How do you know Paul Campano?"

"I knew him when I was ten years old. We didn't get along."

"Is that why he doesn't want to talk to you?"

"It could be," Will admitted. "But I think my knowing him might also be a way in."

"Hoyt Bentley has posted a fifty-thousand-dollar reward for information leading to his granddaughter's safe return. He wanted to come out of the gate with half a million, but I managed to talk him down."

Will didn't envy her the task. Men like Bentley were used to being able to buy their way out of anything. A more lucrative reward would have backfired in so many ways, including bringing out every fruitcake in the city.

"I bet you they're going to hire their own people to stick their noses into this."

Will recognized a sucker bet when he saw one. Atlanta's wealthy had a bevy of private security forces at their disposal. Hoyt Bentley had enough money to buy every last one of them. "I'm sure Paul and his father-in-law think they can take care of this themselves."

"I hope whoever they hire knows the difference between paying off a CEO's mistress and negotiating a ransom."

Surprised, Will said, "Do you think there will be a ransom demand?"

"I think there will be several—none of them from our kidnapper." She crossed her arms, leaning against the counter. "Tell me what's bothering you."

Will didn't have to think in order to answer her question. "Two teenage girls, at least one teenage boy, alone in a house during the middle of the day. The parents don't know where any of them are. They say their daughter has changed lately, that she's been acting out. Somebody had sex in that bed upstairs. Where were Emma and Adam when Kayla was being butchered? Where was Emma when Adam was stabbed?We have toask whether ornot Emma Campano is a victim or an offender."

Amanda let that sink in, considering the possibilities. "I'm not saying you're wrong," she finally told him. "But there's a big difference between being a rebellious teenager and being a coldblooded killer. Nothing about the scene points to anything ritualistic. I'm not saying you're wrong to consider the possibility, but let's just treat this as a straight abduction until we find something that points to more nefarious origins."
