“I won’t,” Kevin said.

Slater tilted the gun and shot him in the foot.

He gasped. Pain throbbed through to his sole and then spiked up his shin; nausea rolled into his gut. The Reebok on his right foot had a red hole in it and was trembling. His horizon tipped.

“You will.” Slater blew imaginary smoke from the barrel. “I promise you, Kevin. You most definitely will.”

Sam ran for him and caught his sagging body. He let her support him and adjusted his weight to his left foot.

Sam jerked her head toward Slater. “You’re sick . . . You didn’t need to do that!”

“A hole in the foot, a hole in the head; we’ll see who ends up dead.”

“I love you, Sam,” Kevin said softly, ignoring the pain. “No matter what happens, I want you to know how lost I am without you.”

Jennifer paced. “I could strangleher!”

“Call her,” Dr. Francis said.

“And risk exposing her? She could be right outside his door and her cell goes off? Can’t do it.”

He nodded. “Something doesn’t sit right.”

She picked up her phone. “I had myself firmly convinced that Kevin was Slater.”

“And he isn’t.”

“Unless—”

Her cell phone chirped. They both looked at it. Jennifer flipped it open.

“Hello?”

“We have the report from Riggs,” Galager said. But Jennifer already knew that Slater and Kevin weren’t the same person.

“Bit late. We already know. Anything else?”

“No. Just that.”

She sighed. “We have a problem, Bill. What’s the mood over there?”

“Gloomy. Frantic without direction. The director just called for you. He’s getting an earful from the governor. Expect a call any second. They want to know.”

“Know what? We don’t know where he’s stashed Balinda. We’re down to a few minutes and we don’t have the faintest idea where he’s taken her. Tell them that.”

Galager didn’t respond right away. “If it’s any consolation, Jennifer, I think he’s innocent. The man I talked to wasn’t a killer.”

“Of course he isn’t a killer,” Jennifer snapped. “What do you mean? Of course . . .” She turned to the professor. His eyes were fixed on her. “What did the report say?”

“I thought you said you knew. The voices on the recording are from the same person.”

“The seismic tuner—”

“No. The same person. In Riggs’s estimation, if the recording is Kevin and Slater, then Kevin is Slater. There’s an echo in the background that barely surfaces on the second tape. Both voices are from the same room. Riggs’s guess is he’s using two cell phones and the recording picks up a faint reproduction of what he’s saying on the other phone.”

“But . . . that’s impossible!”

“I thought it was the prevailing theory . . .”

“But Sam’s with them, and she called us. Kevin isn’t Slater!”

“And what makes you think you can trust Sam? If she’s with them, didn’t she tell you where they are? I’d bank on Riggs.”

Jennifer stood frozen to the carpet. Was it possible? “I have to go.”

“Jennifer, what do I—”

“I’ll call you back.” She snapped the phone closed and stared at the professor, dumbstruck.

“Unless Sam didn’tsee them both.”

“Did you ever meet with Sam?” Dr. Francis asked. “Actually see her with your own eyes?”

Jennifer thought. “No, I didn’t. But . . . I talked to her. So many times.”

“So did I. But her voice wasn’t so high that it sounded necessarily female.”

“Could . . . he do that?” Jennifer scrambled for understanding, searched for something, anything Sam had done that might contradict the notion. None came immediately to mind. “Cases of many more than two personalities have been documented.”

“What if Slater isn’t the only one who’s Kevin? What if Samantha is also Kevin?”

“Three! Three personalities in one.”

SAMANTHA WATCHED THE SECOND HAND tick relentlessly through its slow arc. Kevin sat on the floor, head in hands, distraught. Balinda slumped in her chair five feet to his left, mouth taped gray, eyes flittering over Kevin. If Kevin’s aunt could talk now, what would she say? I’m so sorry, Kevin! I beg your forgiveness! Don’t be a coward, Kevin! Get up and kick that man where he’ll remember it!

Balinda never looked at Slater. It was as if he didn’t exist. Or she couldn’t bear to look at him. For that matter, the woman didn’t look at Sam either. Her attention was consumed by Kevin and Kevin alone.

Sam closed her eyes. Easy, girl. You can do this.

But in all honesty she was no longer feeling like she could do this or anything. Slater had two guns and a big smile. She had only her cell phone.

“Uh, uh, uh, hands where I can see, darling.”

Jennifer ran her hands through her hair. “This is crazy!” Her head hurt and time was running out. Think!

“She was always disappearing! She—he could have made it all up. The CBI, the task force, the interview with the Pakistani, all of it! They were all things she could have created in her mind based on information Kevin already knew.”

“Or that Kevin simply fabricated,” Dr. Francis said. “Kevin concludes that Slater can’t be the Riddle Killer because deep in his subconscious he knows that heis Slater. Sam, his alter ego, concludes the same. She’s working to free Kevin without knowing that she ishim.”

“She kept suggesting that there was someone on the inside! There was—Kevin! He was on the inside. And she was the one who first concluded that Kevin was Slater!”

“And to Kevin, both Slater and Samantha are as real as you and me.”

They were running over each other with their words now, connecting dots that formed a perfect picture.

Or did they?

Jennifer shook her head. “But I just talked to Sam and she saw Kevin and Slater while she was outsidethe door. You’re saying that I was actually talking to Kevin, and that he was simply imagining himself as Samantha, sneaking up on him and Slater?”

“It’s possible,” the professor said, excitedly. “You’ve read the case studies. If Kevin is truly split, Sam would have her own personality. Everything she’s done has been done completely in Kevin’s mind, but to both of them, it has been completely real.”

“So it was Kevin I just talked to.”

“No, it was Sam. Sam is distinct from Kevin in his mind.”

“But physically, it was Kevin.”

“Assuming she is him, yes.”

“And why didn’t Slater stop him? If Slater was there as well? Kevin picks up the phone and calls me, and in his mind he’s really Samantha, outside the door. Makes sense. But Slater’s there too. Why doesn’t he stop the phone call?”

“I don’t know,” the professor said, turning with hand on chin. “You’d think he’d stop Kevin. So we could be wrong.”

Jennifer massaged her temples. “But if they areall Kevin, it would mean he never even had a childhood friend named Samantha. He created her as an escape to fill the void in his life. Then he created Slater, and when he discovered that Slater hated Sam, he tried to kill Slater. Now Slater’s come back and so has Sam.” She turned. “But her father was a cop! He lived in the house three down from Kevin’s.”

“Kevin could have known that a cop named Sheer lived in that house and simply built Samantha’s reality on that. Do you know whether Officer Sheer even had a daughter named Samantha?”

“Never checked.” Jennifer paced, sorting through the tide of thoughts. “It does make sense, doesn’t it? Balinda wouldn’t let Kevin have a best friend, so he fabricated one. He role-played her.”

“This is what Kevin could have meant when he told me he had a new model for the natures of man,” Dr. Francis said. “The three natures of man. Good, evil, and the man struggling between! ‘The good that I would, that I do not, but that which I would not, that I do.’ There are really three natures in there! One, the good. Two, that which I would not. And, three, I!”
