Mac, Jason, Danny and Don were going down the hall toward Xavier Narrow's apartment. "We don't know if this guy is guilty of anything," Mac said. "But let's use caution anyway."

They walked up to the door and Mac knocked. They soon heard someone unlocking the door. There was a man at the door who was very tall. He had a dark complexion and was dressed in a long-sleeved red t-shirt and jeans. "Can I help you?" he asked.

Mac showed him his badge. "Yes," he said. "Are you Xavier Narrow?"

"Yes. What's this about?"

"I'm Detective Mac Taylor. We're investigating a murder. Could we come in and ask you some questions?"

"Do you have a warrant?"

Mac reached inside his jacket and pulled out the warrant. "Yes, we do."

Narrow opened the door and let them in as he took the warrant from Mac. "So, what are you here about?" Narrow asked. "I don't know anything about a murder."

"Mister Narrow, do you recall going to a police auction about a year ago?" Mac asked and showed him the file about it.

Narrow put his glasses on and looked at the paper. "Yes, I bought a weapon at that auction," he said. "I'm a collector."

"And you collect weapons?"

"Yes. I'll show you."

Mac and the others followed Narrow to another room in the apartment. Mac stared around the room at all the weapons that were hanging on the walls and the weapon's cases sitting around the room. He looked at Narrow. "You collect weapons that were used in crimes?" he asked.

"Not always," Narrow replied. "I just collect weapons but I do have some that were used in crimes."

"Do you have this one?" Mac asked, referring to the paper he had shown Narrow before.

"Of course."

Narrow went over to a cabinet and took out a metal case and brought it to a table that was in the center of the room. He unlocked the case and opened it. Narrow frowned as Mac and the others leaned to see what was in the box. Narrow looked at Mac in surprise. "It's gone," he said.

Mac stared at the box and then looked at Narrow. "Are you telling me that you didn't know that gun was gone?" he asked.

"I keep it locked in this box."

"Does anyone else have access to this room?"

"No. No one lives with me."

"Have you had anyone over lately?"

"Not in quite a while."

"How long ago?"

Narrow folded his arms. "I don't have to tell you about my personal life," he declared. "That warrant is only for you to search for that gun, not to get into my personal life."

Mac stared at him a moment. "Well, since the gun is missing and you don't want us to think you had anything to do with this murder, I think you would want to tell us who has been here."

Narrow frowned and unfolded his arms. "I had a lady over about two months ago, I guess. We met at a bar and we had a mutual attraction."

"What was her name?"

Narrow sighed. "We didn't go into any details, we just made each other feel good. I know it's risky but it was just for one night."

"How long did she stay?"

"All night."

"So you wouldn't know if she came in here and got into anything."

"How would she get into it?"

"If a person wants something, they'll find a way to get it. Can you describe her?"

"She was blond, about five-three, green eyes and sexy."

"Did she say anything about where she works?"

"She said she is a fitness instructor."

"Where?"

"She didn't say but man, she was fit alright. That must have been true."

Mac scowled at the man. "You have a habit of picking up strange women?" he asked.

"No but there was something about her."

Mac wrote down the description and the details. "Did you show her your beloved collection?" he asked.

Narrow thought a moment. "I told her I was a collector of weapons."

"And did she ask you any details about them?"

"Not much. She just asked what kinds of weapons and I told her I collected weapons of all kinds and I had a special room that I kept them in."

"Did anyone bid against you in that auction?" Jason asked.

Narrow thought a moment. "Come to think of it, there was someone bidding against me on the phone," he said. He looked at Mac. "You don't think it was her, do you?"

"Who knows?" Mac asked. He put gloves on and closed the box that the weapon had been kept in. "I am going to have to take this."

"Will I get it back?" Narrow asked.

"When this crime is solved."

Mac put the box in an evidence bag. "You haven't looked at this box since that woman was here?" he asked.

"No," Narrow answered. "I hardly ever open the boxes unless I'm showing them to someone. I just keep them."

Mac looked around the room. "If you find anything else missing let us know," he said as he gave Narrow a card.

Mac, Don, Danny and Jason went back out of the apartment. "Can you believe that?" Don asked.

"Believe what?" Mac asked.

"He just picked up a strange woman and brought her back here."

"I can believe anything. She must have seduced him so she could get that weapon."

"Dad, don't you think that is strange?" Jason asked.

Mac stopped at the elevator and pressed the down button. He looked at Jason. "What do you mean?" he asked.

"A woman seduced this guy so she could get that particular gun?"

Mac stared at him a moment. "What are you getting at?" he asked.

"Dad, don't you think you should consider that your friend, Christine could be a suspect?"

"Christine?" Don asked. "Who's that?"

"Her brother was Dad's partner when he was killed in the line of duty and he was killed with that same gun that killed the two victims."

Don and Danny looked at Mac. "You're kidding," Danny said. "You mean she's a friend of yours?"

"Yes," Mac said.

The elevator doors opened and they all walked in. "Mac, you didn't tell us anything like that," Don said. "What does she look like?"

Mac sighed. He knew that description that Narrow had given sounded like Christine. But that could be any number of women. If they lined up every woman in this town who fit that description, he would have an extreme number of suspects…but then again, how many of them had a brother murdered by that weapon. "Alright," he said. "I have to admit that it is suspicious and that she fits that description. I just can't believe Christine would murder someone. And why this EMT and this lawyer?"

"What were the circumstances that went along with your partner's death?" Danny asked.

Mac told them what happened. "He died from hemorrhaging inside," he said. "If I had stayed with him…"

"Don't start blaming yourself," Jason said. "I read that report. You couldn't have helped him." He paused a moment. "Maybe that's what her angle is. Maybe she thought the paramedics should have gotten there quicker or this lawyer defended the one who killed her brother."

Mac considered that. He had to admit Jason was right. "We'll have to look into all that."

"Mac, if this paramedic happens to be the one who responded when your partner was shot and that lawyer happens to be the one who defended the guy who shot him, she's going to look really guilty," Don declared.

Mac frowned. He could not remember the names of the paramedic or the lawyer. After all, that had been over twenty years ago. He hoped it was not Christine who had killed these people. He did not want to have to arrest her and put her in prison. He did not think she would kill anyone but he would have to put her up as a suspect if they found out that these two people had been involved in that case. There was also the fact that someone was harassing him with flowers and notes…and he had also been told that someone wanted to kill him.

Mac felt cold inside as they headed back to the lab. It just could not be Christine…
