"What about the gun?"
"He mentioned it for a reason, but I checked his book bag and his dorm top to bottom. If Adam bought a gun, he didn't give it to Gabe. Maybe he kept it in his car."
"Which means our abductor probably has it," Will pointed out. "Where was Gabe yesterday when this was all going down?"
"In a class, but it was in one of those huge lecture halls. He didn't have to sign in, the teacher doesn't take attendance. It's a shaky alibi." She paused. "Listen, if you think I made a bad call, we can go pick him up right now. Maybe sitting in a jail cell will jog his memory."
Will did not relish the prospect of sweating an eighteen-year-old kid based on a hunch, especially considering Gabe Cohen's suicidal ideation. He listed the points in Gabe's favor. "He doesn't have a car on campus. He doesn't have a place to hide Emma. We have no connection between him and either girl. No motive, no opportunity, no means."
"I think he's troubled," she said. "But I don't think he's capable of this sort of thing." Faith laughed. "Of course, if I was good at spotting the ones who had murder in their hearts, I'd be running the world."
It was a sentiment Will had often thought himself. "What's the school doing with him?"
"Victor says it's a delicate situation," she said. "They're really caught in the middle."
"How so?"
"Do you remember the dozen or so suicides at MIT back in the nineties?"
Will nodded. The stories of parents suing the university had made national news.
"The schools have a legal obligation—in loco parentis," she cited, the phrase that basically said the school acted as parents to the students while they were enrolled. "Victor's going to recommend to the father that Gabe be committed for psychiatric evaluation."
Will couldn't help but notice that she kept using the dean's name. "Have him committed?" he asked. "That seems kind of drastic."
"They have to be careful. Even if Gabe's just blowing smoke, they have to take him seriously. I doubt Tech will allow him back in without a doctor's assurance that he's okay." She shrugged. "Even then, they'll probably make him check in with counselors every day."
Will liked the idea of Gabe Cohen being on psychiatric lock-down instead of left out in the world to his own devices. At least this way, he knew how to get his hands on the kid if he wanted to.
He said, "Let's go back to the murders."
"All right."
"Kayla was killed by someone who hated her. I can't believe the killer would take that much time with her otherwise. All those stab wounds, pulling down the underwear, pushing up the shirt. Classic debasement and overkill. You don't punch somebody's face off unless you know who they are and despise them for it." He suggested, "Maybe you're right. Maybe Emma snapped."
"She would have to kill her best friend—beat her, stab her, possibly rape her with something that, according to Pete, had a condom on it—then hit Adam over the head and stab him, then create this hoax for her parents to fall for." She added, "And that still doesn't explain the sperm found in Kayla Alexander's vagina."
"Or maybe Emma just stood by while it was all happening." He reminded her, "Charlie says there were four people in that house."
"True," Faith conceded. "But I have to put this in there somewhere: for a girl like Emma Campano, living where she lives, having the father and grandfather that she has, a million dollars isn't a lot of money."
Will hadn't considered that, but she was right. Ten million would be more on par with Paul's lifestyle. Then again, one million would be a lot easier to hide.
He said, "Bernard, Emma's teacher, said that she was highly organized. This took a lot of planning."
Faith shook her head. "I don't understand kids anymore. I really don't." She stared out the window at the apartments next door. "I hope I did the right thing with Gabe."
Will gave her one of Amanda's more solid pieces of advice. "You can only make decisions with the information you have at the time."
She was still looking out the window. "I've never been up to this floor before."
"We try to keep out the hoi polloi."
She smiled weakly. "How did it go with the Humphreys?"
"As bad as you would expect."
Faith chewed her lip, still staring out the window. "When I first saw Adam yesterday, all I could do was think about my son. Maybe that's why I missed so many things. We lost hours when we could have been looking for her."
It was the most personal thing she had ever shared. Will had said so many wrong things to her lately that he knew better than to try to comfort her.
"I feel like we should be doing something," she said, her frustration obvious.
He told her the same things he had been telling himself. "It's a waiting game now. We're waiting on Charlie to process the evidence. We're waiting on the fingerprint guy. We're waiting on—"
"Everything," she said. "I'm half tempted to follow up nutjobs from the tip line."
"That wouldn't be the most productive use of your time."
Faith sighed in response. She looked bone-tired. Will imagined that getting some sleep was probably the only productive thing they could do tonight. Being fresh tomorrow morning when some of the evidence came in was key.
Will told her as much. "We'll have more to go on tomorrow morning." He checked the time. It was almost nine o'clock. "They're going to turn off the air-conditioning to the top floors in ten minutes. You should go home and try to get some sleep."
"Empty house," she told him. "Jeremy is enjoying his independence a little too much. I thought at least he'd miss me a little."
"I guess children can be stubborn sometimes."
"I bet you were a real handful for your mother."
Will shrugged. He supposed that was true enough. You didn't stick a baby in a trashcan because he was easy. "Maybe I could..." Will hesitated, but decided he might as well. "Would you like to go get a drink or something?"
She startled. "Oh, my God."
He realized two seconds too late that he'd put his foot in his mouth again. "I have a girlfriend. I mean, a fiancée. We're engaged." The details rushed out. "Angie Polaski. She used to work vice. I've known her since I was eight."
She seemed even more startled. "Eight?"
Will realized he should close his mouth and think about what he was saying before he let it out. "It sounds more romantic than it actually is." He paused. "I just... you said you didn't want to go to an empty house. I was just trying to ...I don't know." He laughed nervously. "I guess my feral monkey is acting up again."
She was nice about it. "We've both had a long day."
"I don't even drink." Will stood as Faith did. He put his hand in his pocket and felt something unfamiliar mixed in with the change. He pulled out the vial with the gray powder in it, surprised the plastic hadn't broken during his scuffle with Paul.
