Police Station

Mikki had quite a glow on her face. She hadn't gotten that into sex in, who knows if she was ever that into sex. Katie was just a sex pistol. She wanted more and more, and Mikki was happy to give it to her.

Sue came to visit. "How was last night?"

Mikki was beaming. "It was nice."

"Nice, my ass. You got her in bed didn't you."

Mikki just smiled. Her expression said it all.

"I have to admit. She's pretty damn gorgeous."

"I know, right."

"You have plans with her tonight."

"I'm not going to rush into anything."

"You might not have a choice. Girls like that don't come around every day."

Chicago

The background check came in. The father seemed to be a pretty good guy. They spoke to his relative, who said nothing but good things. After school, they were going to talk to Marcus about the whole thing.

He came in on the bus.

"Marcus, Come here please."

He came quickly. "Yes, Grandpa."

"We need to talk." Molly was napping. He decided this would be easier as a man to man conversation.

"I'm sure you've noticed, but your grandma and I are getting old. She's been sick. My health is failing."

"I can do more around the house."

"It's not that, Marcus. It's just, you're a growing boy. You need to be raised by people who can be there t take care of you. We won't be able to do that forever."

"I'll be better. I promise."

"You've already been the best grandson a man could ask for. This isn't about you. I mean it is, but this isn't your fault. We found your father."

"What? The man who ditched me."

"We don't know that. We don't even know if he knows you exist. We never had his name. You remember that swab I had you take."

"Yeah."

"We sent it to a lab to test your DNA against known people in the database. We found a familial match. She sent us her information, and we found your father." He showed Marcus the file.

"You're not sending me away, are you?"

"We don't know. We think we should meet him and see what kind of man he is, but if he's a good man, it will be better if you go stay with him."

Marcus's heart sank. He had never known other parents, and he didn't want to start now.

"You're growing up to be a man. You need someone to show you the way. I know this is hard. It's crushing me right now, but if anything happened to you because your grandmother and I couldn't protect you, I would never forgive myself."

Marcus gave his grandfather a big hug. He didn't want to go anywhere.

Major Crimes

A woman has been getting threatening phone calls, and today, someone sent her a mysterious powder. The letter got seized by the post office and sent to the FBI lab for analysis.

Sharon interviewed her. "I bet it's my ex-boyfriend," the woman started. "We broke up 4 months ago, which was fine but about 2 months ago, I got a new boyfriend, two weeks later, the calls started."

"What would they say?"

"Stupid things like "you're making a mistake.' 'You don't know what you've done to me.' 'You'll pay for this.'"

"Did you call the police?"

"I did but they couldn't prove it. He didn't call from his cell phone and I couldn't recognize the voice. It sounded like someone was using a computer."

"Did you ever confront him?"

"My boyfriend did. He denied it all."

"I'll need both of their names."

Flynn and Provenza picked up the ex-boyfriend, Dennis Wheeler. He said nothing and came with them.

"Do you know why you're here?" Sharon asked him.

He shook his head.

"Someone tried to hurt Macy."

"I wouldn't do that. I love her."

"But she doesn't love you. She has a new boyfriend."

"I know. I asked her to get back with me, and she said no. I haven't spoken to her since."

"You didn't call her house."

"No way. Her stupid boyfriend came by my work to harass me. My boss had to kick him out."

"Where do you work?"

"I'm a mechanic at Ace's Auto Shop. Is Macy okay?"

"She's fine, but someone tried to poison her."

"I wouldn't do that." Sharon actually believed him. He looked heartbroken but not sick or crazy.

"Do you know who would?"

"Her neighbor is weird. He gives me the creeps. When I used to leave her place in the morning, he would always be in his front yard watching, leaning on his lawnmower."

"You thought it was odd that he mowed the lawn."

"I don't think he was mowing anything. I think he was just watching her door. He was creepy."

"Does he have a name?"

Martin Fink. He lives on the door to the right.

Sanchez and Sykes found the boyfriend. When Flynn escorted Dennis out of the interview room, Martin tried to punch him.

"I'll kill you, you jerk."

"Macy's too good for you. She always will be."

Martin got angrier but Sanchez held him down.

"Martin," Captain Raydor began. "Please, Sit down."

"Have you arrested him? He did it."

"How do you know?"

"First, he stopped by to pick up forgotten items from her house. Then, he offered to fix her car for her. He was always sniffing around and when Macy shot him down, he snapped."

"When was this?"

"About 6 weeks ago." Same time the calls started, although that doesn't prove anything.

"When did you start seeing Macy?"

"About two months ago. We knew each other before."

"From where?"

"She works with my sister. We met at an office party."

"Where does your sister work?"

"They're both scientists for Pfizer. Why does this matter?"

"In order to build a case, we need to know the environment."

"Well, it was Dennis alright, and you better get him, or I will." Martin left.

Ring Ring

"Hello"

"Hey Captain, it's Fritz. The preliminary results from the letter are in. According to our lab, it was white phosphorous."

"How would a mechanic get white phosphorous?"

"He wouldn't. It's something that you would find in a military weapon."

"Or in a lab."

"If you had a chemist that could produce it, yes."

"Thanks Agent Howard."

Tao called Pfizer. As it turns out, Macy just got a big promotion. She was in charge of their search for a medicine that would cure opiate addiction. Ina, Martin's sister, had a similar proposal, but they liked Macy's plan better.

Pfizer lured Ina from her station, offering her a free lunch. HAZMAT checked the lab, and found exactly what you needed to make white phosphorous. They got a search warrant for her house to get her personal computer. They found the voice program she used to make the phone calls and the program she used to make the call untraceable

They brought in Ina.

Sharon started easy, buttering her up, saying they needed her expertise. They said Dennis was the suspect, but they couldn't figure out how a mechanic was smart enough to make a poison. Ina explained it all readily, every step, pretending Dennis had done it all. She didn't even realize she described perfectly how to make white phosphorous.

"That's so funny," Sharon said.

"What's so funny?"

"I asked you how to make poison and you described white phosphorous, the same poison sent to Macy."

"You said that was the poison."

"No, I didn't."

"She must have mentioned it then."

"We haven't told her yet what it was."

Sanchez saw his cue and came in. "We found these programs on the computer in your house. They recreated the voice she used to harass Macy."

"It must have been hard," Sharon started. "You got her that job at Pfizer. You introduce her to your brother. She steals the job you worked so hard for, and she takes home your brother. She wasn't very grateful was she."

"She stole my idea. I told her about my plans to make a cure for opiate addiction and she took it right from under me."

"That's so odd," Sharon continued. "As you can see here, she wrote her dissertation on the complications of using drugs to cure addictions. It seems she's been working on this a long time."

"She had a vague notion, but she stole the chemistry from me. She deserved what was coming to her."

"What about the post office employees? Did they deserve your wrath too? What about the people who worked in your lab? Any of them could have gotten hurt!"

"I think I've said enough."

Sharon called Macy. She told them they arrested Ina. She did it all.

She was upset. She thought she and Ina were friends. She was going to ask Ina to be the assistant leader of this project. She thought they could have done it together.

Macy was on her way home when she bumped into Dennis.

"I'm sorry," she told him. "I can't believe I thought you could have done this."

He looked into her eyes. They were sad. They shared a moment. "Do you want me to walk you to your car?"

"That piece of junk doesn't work."

"It just needs a little attention."

"And a lot of money."

"Maybe there's something in the shop that will help."

"Really, you'd help me after all of this."

"I'll never give up on you," he told her.

"What a chump!" Provenza declared as they left the building.

Flynn laughed as did Sanchez.

"I think it's sweet," said Sykes.

"What, that he's still head over heels for a woman who's with another man and thought he was trying to kill her?"

"I saw the look in her eyes. I think she knows that she let go of a great guy, and she might be ready to make up."

"You and you're optimism." Provenza rolled his eyes and went back to his paper.

"Was that the fastest we ever solved a case?" asked Tao.

"The FBI is all over poisonous letters in this day and age."
