A/N: Just want to apologize for taking forever and a day to update this. I got occupied by another fandom, and with the lack of new episodes that kind of led to a lack of inspiration for me. But I finally finished. Here's the final chapter. Enjoy!

Sharona rolled her eyes when a guard led her into an interrogation room and she saw Monk there. The guard uncuffed her, shut the door and locked it.

"So, what do you want now?" she asked in annoyance. "Ever since I met you I've been arrested for murder, my kid's getting into fights at school and I've been fired. Oh, and I just found out that my landlord is trying to evict me. Did you come to tell me my grandmother's dead?"

"I came to apologize," Monk said. "We were wrong, and I'm sorry."

She was definitely taken aback. That wasn't what she was expecting him to say. "What are you talking about?"

"I know you didn't kill Mitchell Vernon," he replied.

"Then why am I still here?" Sharona asked, gesturing around the room. She sat down at the table.

"We don't have any proof yet," Monk said. He sat at the table across from her. "The DA wants more proof before he'll drop the charges against you. Which is also why I'm here." Monk pulled out the picture of Kathleen and Michael Shaw. "Do you recognize this man at all?"

Sharona took the picture and stared at the man for nearly two minutes. Then it hit her and she looked up. "That's the orderly that I saw coming from Mr. Vernon's room that morning. Who is he?"

"He's no orderly," Monk replied. "He's Dr. Michael Shaw. Mr. Vernon's son-in-law."

"Michael Shaw? He's a psychiatrist. I read one of his papers when I was in school," Sharona said in disbelief. "Do you think he did this?"

Monk nodded his head. "And you identifying him takes me one step closer to proving that." Monk looked at his watch. It was almost seven-thirty. "What time does the other nurse on your shift start?"

"Same time. Nine o'clock," she replied. "I don't know if she saw him or not."

"Well, I'll have to ask her," Monk said. He stood, went over to the door and knocked on it. They could hear the lock clicking and then the door opened. Before he left Monk turned back to Sharona. "I'll get you out of here."

She offered a small smile and nodded her head as the guard cuffed her wrists. Monk left, determined to do just as he said.

After stopping for a late dinner with Trudy, Monk picked Disher up at the station and headed for the hospital. It was a little after nine when they arrived, flashing their badges for the outside security camera and signing the guest sheet. They headed up to the second floor.

"A lady that lives across from Richard Vernon's building says she saw Michael Shaw leaving just shortly before Vernon died."

"I figured as much," Monk said. They found Whitney at the nurses' station. When she saw Disher, her eyes narrowed.

"You again," she said.

"We need to ask you some more questions," Disher said.

"What? Did you not get enough evidence to keep Sharona in jail?" she walked around and started pushing a cart down the hall. "You got questions, we'll have to walk and talk. I have to make my rounds."

"Sharona mentioned that she saw a new orderly coming out of Mr. Vernon's room at about 5:30 the morning that he was murdered," Monk said. He pulled out the picture of the Shaws. "Do you recognize the man in this picture?"

Whitney paused and looked at it for a moment. "Yeah, I saw that orderly that morning. He was leaving the floor right after I finished my rounds." She looked at the picture again and her eyes widened. "Wait a minute. That guy's not an orderly. He's a psychiatrist. Dr. Shaw. He consults on psych cases sometimes."

"You know him?" Disher asked. Whitney shrugged her shoulders.

"I met him when I was down in the ER," she said. "Didn't really have a chance to talk to him. Why would he be up here pretending to be an orderly?"

"That's a good question," Disher said with a smile. He saw Monk shared that smile. They both knew the answer to the question. They followed Whitney into a patient's room. She pulled a package out and opened it, revealing a syringe. Monk grabbed her arm.

"You just took that syringe out of a package," he said. She looked at him in confusion.

"Yeah, I always do," she said.

"You use a new syringe every time? Even if it's for the same patient?" he continued.

"Sure," she replied, continuing about her work. "It's policy. We never use the same needle twice. It's almost an unconscious habit. I've never even thought of reusing a needle."

"Come on, Randy," Monk said, taking his partner's arm. "We've got everything we need. Thank you, Ms. Harmon. I promise you'll see Sharona back soon."

Monk led Disher out of the room before anybody could say another word. On the way out, Monk made sure to get a copy of the security sign in lists for the week from the desk.

It took a couple hours, but Monk and Disher were able to get a warrant. So when they showed up at the Shaws' home, it wasn't a surprise that Michael was in his pajamas.

"Now what do you people want? My father-in-law is dead," he said angrily. "I'm getting sick of your harrassment."

"Your brother-in-law is dead, too," Monk said. "But you already knew that, didn't you?"

"Richard's dead? What happened?" he asked, apparently shocked by this news. Kathleen walked up behind him and he turned to tell her, signing as he spoke. "Honey, they just said Richard's dead."

"What?" she asked, her eyes wide as she signed. She turned to Monk and Disher. "What's going on?"

"Mrs. Shaw, we have warrants for the arrest of your husband for the murders of your father and brother, and also a warrant to search your home," Monk said.

Disher pulled out his cuffs. "Mr. Shaw, you have the right to remain silent."

"What the hell? I'm not going anywhere with you," Shaw said, backing away.

"Anything you say can and will be used against you in a court of law," Disher continued. "You have the right to an attorney. If you can't afford an attorney, one will be appointed by the courts. Do you understand the rights I've just given you?" He reached for Michael's wrists again, and he pulled away again.

"I understand my damn rights. What I don't understand is why you're trying to arrest me," he said. "I didn't kill anybody."

"You did, Dr. Shaw," Monk said. "And you did a pretty good job of it. You had us fooled for a little while there. But you made a couple mistakes, especially when you killed Richard."

"It was his idea to kill Mitchell, right?" Disher asked. "That's why you had to kill Richard. You got nervous that he would talk. He had already told us about how exactly you met your wife."

"But there was never any proof that Mitchell was the one who attacked her," Monk said. "So you made your own justice."

"Honey, what are they talking about?" Kathleen asked.

"They don't know what they're talking about," Michael said and signed.

"Don't we?" Monk asked. "You consult at the hospital. That's how you got in after visiting hours. Only hospital staff is allowed in after visiting hours. And even then you have to sign in. You signed in under your own name and then went up to the second floor, posing as an orderly. You didn't do a good job of avoiding witnesses."

"Sharona Fleming saw you leaving Mitchell's room," Disher added. Michael laughed.

"She's your eye-witness? She's in jail! Of course she's going to point the finger at me or whoever else she can."

"The other night nurse saw you leaving the floor that morning," Disher added.

"We couldn't figure out how Sharona's prints got on the syringe used to kill Mitchell. That had me stumped until I read the lab report and saw a nurse use a syringe tonight," Monk said. "The syringe had traces of water and morphine in it. With the water in it, we just assumed she rinsed a syringe she had already used. It didn't really make sense. Then I saw a nurse open a package with a brand new syringe in it. They use a new syringe every time. It's procedure…and habit."

"She was murdering somebody. She's not going to follow hospital procedure," Michael scoffed.

Monk ignored him. "You needed to frame somebody for Mitchell's murder. So you took a syringe out of the medical waste and rinsed it out. Then you filled the syringe with morphine and murdered your father-in-law. You went to medical school. You know how to find a vein."

"What's my motive?" Michael asked.

"Vigilante justice. Nobody was arrested for raping Kathleen because she couldn't remember who attacked her, and there was no evidence. There was no evidence because Mitchell Vernon attacked her in their own home and then cleaned it up before the police could find anything," Disher said.

Michael looked at Kathleen who was staring at him in shock. Her eyes were welling with tears.

"Honey," he said, stepping forward. She backed away and Disher took the opportunity to pull Michael's arms behind his back, cuffing them. "Mitch nearly killed you. He couldn't get away with it." She signed something and he shook his head. "No, our marriage wasn't a lie. I did this because I love you."

"Some people buy their wives flowers or jewelry, Dr. Shaw," Monk said. Disher pulled Michael toward the door. Monk turned to Kathleen as Michael was escorted out of the house. Tears were running down her face. "I'm sorry. Is there somebody I can call for you?"

She shook her head. Monk didn't know what else to do. He followed Disher out of the house as uniformed officers showed up to search the house of their murderer.

Sharona squinted in the sunlight as she stepped out of the police station, thankfully wearing her own clothes. She had just been released from prison, all charges dropped. Now she hoped she could get the mess this all caused cleaned up and get her life back to normal.

"Mom!" Benjy yelled as he ran over to her. She stumbled backward when he wrapped his arms around her in a big bear hug. Gail smiled as she walked over.

"Hey kiddo," Sharona said, returning her son's hug. "I'm happy to see you, too."

Benjy stepped back a little and smiled sheepishly. Then Gail spoke up.

"Max said he wanted to come, but he had to be in court," she said.

"Is he working on all the stuff with my job and my landlord?" Sharona asked. Those two things together scared her. Being jobless and homeless as a single mother wasn't something she felt she could handle.

"That's the weird thing. He called Dr. Parchman and Mr. Troubido," Gail said. "All Dr. Parchman said was that he looked forward to seeing you tonight, and Mr. Troubido said he would never evict one of his best tenants. Apparently somebody already called them."

"Who?" Sharona asked.

"Me."

They looked over when they heard his voice. Monk was walking toward them, with Disher a few steps behind him.

"I felt bad about what happened, and if I had listened to my instincts we never would have put you in jail in the first place," he said. "It was the least I could do."

"Thanks," Sharona said, confused by Monk's actions. "So I really have my job back?"

"I made sure that Dr. Parchman and the hospital's board of directors understood that you had nothing to do with the murder and that we had made a mistake," Monk said.

"I still can't believe Dr. Shaw did it," she said. "Kind of ironic."

"How so?" Disher asked.

"A psychiatrist going psycho," she said with a smirk. Everyone chuckled lightly. After an awkward pause, Sharona decided to break the silence. "Well, I guess we'll head home. I think I'm going to take a really long bath. Thanks again, Inspector Monk."

"You're welcome," he said with a smile. Sharona took her car keys from Gail and they headed over to the car. Monk and Disher started to return to their car.

"Oh, and Disher," she called as she opened her car door. Disher turned back. "You actually do play a pretty good 'bad cop.'"

She laughed, got in the car and drove away, with Benjy waving to the inspectors from the back seat. Disher looked to Monk inquisitively. "Do you think she'd go out with me?"

"What?" Monk asked with a shocked laugh. He turned and walked back to the car.

"Well, do you?" Disher asked again, jogging to catch up.

Monk laughed again. "You're out of your mind."

"You are saying I am out of my mind? Look who's talking," Disher said, pulling the keys out of his pocket.

"Okay, so we're both out of our minds," Monk said as they got into the car.

"Know a good shrink?" Disher asked.

"Yeah," Monk said with a smirk. "But he's in jail."

THE END
