Zoe studied the map again, checking that she had not made a mistake. “It is a diner,” she said. “It looks like the whole space is taken up by the building. I will have to check with the local authority that this map is accurate.”
“No—the killer wouldn’t have been able to do that,” Dr. Applewhite pointed out. “He is going on the same data that you have. A publicly available map. Trust in what you see.”
“Then it is only part of the building. The front area, facing the street with the entrance doors, is not even included. The full boundary encompasses only the middle and back part of the diner.”
“You know where to find him. I suppose you had better hurry—didn’t you say that he always strikes after dark?”
Zoe checked her watch. In the isolated, windowless investigation room, she had not even noticed how far along the day had progressed. It was nearly time for the sun to start going down, and after that it would not take long for him to strike.
They needed to move—and now. She would have to travel along his route, figuring out the roads he would take, where he would be. There was still every chance that Aisha was dead, that he would only arrive to dump her body. Or that she was alive but would not be by the time he reached the diner. Zoe would have to keep her wits about her, and her eyes open.
Leaving the math behind, breaking away from the pattern, felt uncomfortable. Zoe thought it would be the same for the killer, but how could she really know? As much as she understood the numbers with an instinctive resonance, the human mind was something else altogether. That was what truly terrified her and made her heart jump into her throat: the idea that he might deviate now, at this late stage.
“Thank you,” Zoe said, breathlessly, into the phone.
“Don’t mention it,” Dr. Applewhite said. “You can show your gratitude by booking an appointment with that therapist I recommended.”
“I will talk to you soon.” Zoe signed off with a small smile, unwilling still to commit.
There was not much time to be wasted on pleasantries, after all. Zoe knew where the killer was going to be, and she knew when—and it was soon. She ended the call and dialed Shelley’s number instead. They would have to meet there—she could not wait for her partner to get back to their base of operations when someone’s life was going to be on the line.
CHAPTER TWENTY FIVE
Zoe sat at the counter, alone. She was nursing a cup of coffee, but barely drinking it. Instead, she occupied herself by looking around, checking every direction on a regular basis.
She could not stand the waiting. She had considered every angle, every option. That he would bring Aisha in alive, then kill her in the middle of a room full of people. No, that didn’t make sense. That he would bring her in dead—but how would he expect to leave there alive afterward?
Zoe had spent her time approaching the diner carefully, checking the roads, the parking lot, looking inside every car parked there. Not just Ford Taurus vehicles of any color. She was not going to make that mistake twice. No, she had looked over everything thoroughly, and there was no sign of him.
But there was a little light of hope remaining in her heart. This was the fact that there were two kills remaining, not just one. Two locations. And maybe, just maybe, the killer would keep Aisha for last, to make sure his final point would not be ruined.
That made more sense than trying to kill a girl, or bring one already dead, into a crowded diner. He must have known that this would be his ticket to the inside of a jail cell.
And then again, with a schizophrenic off his medication, how could you know that his mind would work logically?
But Zoe had to take a stab. She was only one person, and she could not be everywhere at once. She had alerted Shelley to move in carefully and cover a wider area with the state troopers, observe the parking lot, keep eyes everywhere they could. They were stretched thin with leads in so many different directions now, and the stakes were high. One little movement in the back of a car could indicate Aisha’s struggle. Something easy to miss before her life was over. But the troopers would be out there on the road, in the lot, waiting.
And Zoe was left watching the diner. It seemed unlikely that he would find a victim here, didn’t it? But there were private spaces—the kitchen, the bathrooms. Places a little more out of sight. She just had to watch for suspicious behavior somehow. If he came in, she would see him. She would stop him. She swore that to herself.
