They arrived back at the office with determination. They would find this woman. Mac went to his office and sat down. He stared out the window, just hoping she was watching and that she would call. Adam came in and put the taps on the phone. "If she's watching, she probably knows that I'm doing this," Adam said.

"I know," Mac said. "She may cut her calls short."

"Maybe she won't know what I'm doing."

Just then, Mac's phone rang. Adam flipped a switch. "Go ahead," he said.

Mac picked up the phone. "Taylor," he said.

"Hello, Mac. Did you enjoy the game?"

"You're not tearing me down anymore, Peyton. I'm going to find you. You're going to be behind bars or you're going to be dead. It's your choice. You won't kill anymore people."

"On the contrary. You don't know who's next. It will be someone close to you."

"Why don't you come out of your hole in the wall and show yourself?"

"You think you're ready for a showdown? I suppose you would bring all your little bodyguards."

"You would bring yours too, wouldn't you?"

"Always."

"Why don't you pick a place, and we'll meet?"

"We'll meet on my terms."

Mac heard the phone click. He looked at Adam. "I got the general area," Adam said, "But it wasn't long enough to pinpoint it."

Adam showed Mac the map. "She's close to this building somewhere," Mac said. "She knows when I'm in this office." He looked out the window. "How many buildings out there can actually see into this one clear enough to know when I'm in this office?"

Adam typed on the computer. "According to trajectory and distance, only about five," he said. "She could have binoculars though."

"Lets try those five. Print me out a list."

Mac stood up and waited for the list. "You keep monitoring calls that come in here and my cell phone," he said.

"Yes sir," Adam said.

Mac took the list and went into the lab. "We're going to search these five buildings," he said. "Stella and I will go here." Mac pointed to the list. He gave Sheldon and Sid a building to go to and Danny and Lindsey. He also gave Don one. He would take officers with him. Mac gave them all a picture of Peyton. "See if anybody around there has seen her."

They all headed out. That list left only one building unaccounted for, but they were going for the closest ones first. Mac and Stella went to their building, which was an office building, but it had vacant floors. "How could she be hiding out here?" Stella asked.

"Just acting like she belongs I guess," Mac said.

There weren't many people in the building at this time of night. There was a receptionist down in the lobby. Mac showed her Peyton's picture. "Have you seen this woman?" he asked, and showed her his badge.

The woman looked at the picture. "I see so many people," she said. "I'm not sure."

"This woman is a criminal. I need you to look closer."

The woman looked again. "I might have seen her. I believe I saw her yesterday."

"What floor?"

"Here."

"How many vacant floors are there in this building?"

"About five."

"We need access to those floors."

The receptionist called the building manager, and he came to show Mac and Stella to the vacant floors. The first was the 35th floor. Mac figured it would be easy to see his office from here because it was at the same level. Mac and Stella took their weapons out. "You go on back down," Mac said to the manager. "This is a dangerous woman."

It was dark on the floor, so Mac and Stella had their lights ready. Mac also had his heat sensing equipment on his arm. It was picking up something in the last room in the hall. Mac pointed and Stella nodded. They eased down the hall with their weapons ready and turned their lights off. When they reached the room, they got on either side of the door. Mac gripped the knob and nodded to Stella. Then he shoved the door open. They heard a click. Mac gasped. He ran and grabbed Stella and shoved her back down the hall.

An explosion blew the door and half the wall away as Mac and Stella landed on the floor. They were pelted by debris. Mac did his best to shield Stella. Something hot landed on his back. He yelled out with pain and knocked it away. It was so hot that it had melted a hole in his t-shirt and made a burn on his back. Mac gritted his teeth and groaned in pain. Stella tried to see what happened.

"What happened?" she asked.

Mac was trying to get past the pain. "Burn!" he said.

Stella sat up. She gasped when she saw the burn. It had torn away the top layer of skin. She coughed as smoke came billowing out of the room. "We have to get out of here," she said. She could see the light of a fire inside the room.

Mac got up. "I guess it's safe to assume that she's not here anymore," he said through clinched teeth.

They hurried down the hall, coughing as they went from the acrid smoke. The elevator would not work, so they headed for the stairwell, and just then, the sprinkler system kicked in. Mac moaned as the water stung his burned back. They were soaked by the time they got to the stairwell. By the time they got down, there were fire trucks outside and police, including the rest of the team.

"We knew it had to be you guys when we heard," Don said.

"Are you okay?" Lindsey asked.

"All but a burn," Mac said.

"A severe one," Stella said. "You have to go to the emergency room."

"There's an ambulance here."

Mac went over to the ambulance. They treated the burn. They wanted Mac to go to the ER, but he wouldn't. "You need some cream for that," the paramedic told him. "You have to get a prescription."

"Thanks," Mac said. "I'll get one."

When Mac was out of the ambulance, the others were waiting for him. "She tried to kill us," he said. "They were obviously there."

"She thinks we're closing in," Don said.

"She's got to make a mistake," Stella said. "She can't stay one step ahead of us all the time."

"Somehow, she knows what we're doing and saying all the time," Mac said. "I have to let Adam scan me to see if I have any bugs on me."

"How could you?"

"Buttons, anything."

"Maybe he should scan us all."

When they had been scanned, they found that Mac had a bug on his badge. It looked like one of the decorations. "How did she get that on there?" he asked.

"Maybe when you were out and the badge was in the apartment," Stella said.

"I guess."

No one else had any bugs on them. "Deactivate that thing and put it in evidence," Mac said, "and then scan my office."

"I already did," Adam said. "I found two cameras and three listening devices. I already got them all out."

"Thanks. What about Stella's office?"

"Hers too. I only found a camera and a bug in hers."

"Where do you think she'll go now?" Don asked.

"I don't know," Mac said.

Just then, Don's phone rang. He looked at it. "Crime scene," he said, as Mac's phone began chiming.

Mac looked at the others. "Sheldon, you come with me," he said. "Stella, I want you to stay here. Danny and Lindsey, go home and get some rest."

Mac got his forensics kit, and he, Sheldon and Don headed out. The crime scene was close to where Sid lived. Mac remembered Peyton saying she would get the people close to him. "Who is it?" Mac asked. "Did you get anything?"

"No," Don said.

Mac was anxious to get out there. Sheldon stopped the truck and they got out. Mac hurried to the crime scene. He had to know who this was. It was just too close to Sid's house. She couldn't have killed Sid. He had been her friend too. Mac knew that didn't matter. He had been her lover, and she wanted to kill him.
