Jane shook out her hand, looking at the faint red marks on her wrist. Haywood had one hell of grip. They'd taken him back to holding to calm down, and to give them time to talk to Dr. Mikos when he arrived. She found Maura storing Sara Haywood's body in the coolers. The doctor looked up, scanning her quickly and Jane knew she'd already heard.

Cops gossiped more than school girls. The woman moved toward her fast enough that the white lab coat flared out around her legs. "Are you all right?"

Jane held up her hands. "Yeah. He just grabbed my wrist. Frost got to him pretty quick."

She felt the doctor's fingers brush her hand and let her take it. Maura wouldn't be satisfied until she'd checked it out for herself. The fingers rubbed over the red marks, and her eyes narrowed before she finally let go. "There may be bruising. What happened?"

"He just lost it Maura. He kept claiming that wasn't his wife." She motioned to the coolers. "That she was an imposter."

Jane turned and made her way into the ME's office with the doctor on her heels. "You're saying he was showing disassociation?"

The detective sprawled on the couch, sighing as Maura sat beside her. "I don't know. He thought his father-in-law was an imposter too. If this is him trying to get out of it, he's doing a hell of a job."

Maura was quiet for a moment. "Based on the medications he was prescribed, he has a genuine mental illness."

"Any surprises in the autopsy?"

"Sara Haywood died from stab wounds to the neck and chest. Basically what we already knew." Jane frowned. She was hoping there was some little secret Maura would uncover to nail Haywood without any doubt.

"The guy goes away for a business trip and comes back thinking his wife is a fake. I've never heard of something like that."

Maura was quiet again, not knowing if Jane wanted one of her "fun facts" or not. The woman gave her a look and knowing smile. "Go on."

She smiled back. "There are several syndromes that could be responsible."

"So based on what you know so far which one fits?"

"I'm not a psychiatrist Jane. I'm not going to guess."

Jane's head fell back against the couch and she stared at the ceiling. She loved Maura with all her heart and soul, but sometimes she wanted to choke her. "Could you at least tell me what kinds of syndromes might cause something like this?"

With Maura, simple rewording could get her to answer a question she normally wouldn't.

"Prosopragnosia, Capgras, and several monothematic delusions."

Jane's eyes widened. "That's a mouthful. Mono-what?"

"Monothematic delusion, its where a person is otherwise rational but they have one delusion and its a really, really, big one."

Frustration changed to amazement, and the detective wondered just how smart Maura really was. Her phone buzzed on her hip, and she pulled it off her belt. "Dr. Mikos is here. You want to come help translate doctor speak?"

Maura's smile caused one to cross her own face and she squeezed the woman's hand as she helped her up.

R&I

Dr. Mikos, who looked to be in his mid sixties, was in the bullpen talking with another man Jane easily pegged as a lawyer. She walked up to the with Maura in tow. "Dr. Mikos?" The man turned, "I'm Detective Rizzoli, this is Dr. Maura Isles."

"Detective Rizzoli. I took the liberty of contacting Sam's attorney, Marcus Salk."

Jane nodded, showing them to a private meeting room. They seated themselves quickly. Dr. Mikos studied Jane before asking. "You're sure it was Sara?"

"The victim was identified by her father at the crime scene."

The doctor's face fell. "I was hoping it wasn't true."

Maura leaned forward, "We found several prescriptions. Can you tell us what he was being treated for?"

Jane caught the quick glance to Haywood's attorney before he answered. "I can't break doctor patient confidentiality of course, but I can tell you he was being treated for bi-polar disorder."

"When was the last time you spoke with either of them?"

"Sam had been away on business for the last few days. We had an appointment on Monday to discuss it. Sara called me yesterday afternoon with concerns."

"What kind of concerns?"

Another look to the lawyer. "Again, I can't go into details. She was concerned that he might have had difficulties on the trip. I assured her that everything would be fine. I was obviously very wrong about that."

"Is there anything you can tell us?" Jane was getting annoyed by the half answers.

"Only that he had no history of violent behaviour. I can't understand what would make him do something like this. Is there a way I could speak to him?"

Jane closed up her notebook. "I'm afraid not. Mr. Salk, of course you'll be taken to him immediately, but for now I want him evaluated by one of our doctors."

She was getting up to leave when Dr. Mikos spoke up again. "He is my patient, I will need access to him eventually."

"Once he's been evaluated, we'll see what we can work out. For right now you're too close to this."

Maura followed her out, waiting patiently until they were back in the bull pen before voicing her thoughts. "Can you really keep Dr. Mikos from talking to him?"

"The lawyer didn't seem to mind. Technically yes. He's in no physical danger and I had Korsak get a hold of the station shrink."

Maura grimaced a bit. Jane hated when anyone used a nickname or slang term to refer to her and her job, but she had no problem dubbing the station psychiatrist Dr. Quinn 'Medicine Woman' behind his back. It had taken months for Maura to figure that reference out, but at least it wasn't as profane as the other terms the detective used when referring to the man.

"Short of a court order we won't get his medical records."

"Didn't Dr. Mikos seem a little vague to you? Like he wanted to answer but was scared to?"

"Doctor patient confidentiality is a slippery slope, Jane. Even if he wants to give us all the information he has, he can't. With mental disorders its even harder because the science of it isn't exact. He may not have concrete answers."

"He may also be withholding it to protect himself. I hate cases like this. Nothing is clear cut, there are no answers."

Maura gave her a small smile. "You'll still find them."

'That's not always true.' As soon as the thought hit, she tried to contain it. She didn't always find the answers. The vigilante was a glaring example, and Jane was disgusted over it. Just thinking of it darkened her mood.

"When Quinn gets here I want you in observation with me and Korsak."

"Korsak and I. Of course I'll be there."

Jane rolled her eyes at the correction and allowed herself a small smile. "You hungry?"

At the answering nod she held out her hand. "Let's go see what Stanley has downstairs to poison us."

R&I

Maura stood between Korsak and Jane looking into the interrogation room as Dr. Quinn sat down. Sam Haywood looked tired, and his red rimmed eyes were an obvious sign of recently shed tears.

Salk had insisted on being present during this interview and was sitting quietly in the corner. They also had a patrolman there in case Haywood got violent again. "Good afternoon Mr. Haywood, I'm Dr. Quinn."

The man nodded but said nothing. Quinn studied him for a moment and tried again. "Would you like to tell me what happened last night?"

"There was an intruder in my home."

"The detectives have determined it was your wife."

"How many times do I have to keep telling you that was not my wife!" The patrolman in the corner shifted at the raised voice, and Haywood settled.

"Ok, lets start at the beginning. When did you realize it wasn't your wife?"

"I came home from a trip to New York a few days ago. I had to meet with a client about some accounts in his name. She picked me up from the airport, I felt like there was something off, but I just thought I was tired from the trip."

"That happens to all of us."

Haywood nodded and continued. "It was the next day I realized what was going on. She looked like Sara, she spoke like her, hell she even smelled like her, but it wasn't her. When I looked into her eyes, Sara, my Sara was gone. There was no soul there."

Jane shifted closer to Maura, feeling a chill up her spine. She could only imagine the paranoia that would begin to take over. The fear. Shaking her head to clear it she turned her attention back to the conversation taking place. She didn't notice the glance Maura threw her way.

"What did you do then?"

"I thought about calling the police, but I realized they weren't going to be believe me. I had no proof. Cecil and Mary, my in-laws, they came over for dinner that night, and it was the same with them. No souls, empty shells."

His voice trailed off and he stared at the table. "Did you confront this imposter?"

"Last night. She denied everything. The knife..." He stopped and swallowed hard. "The knife was just to scare her. I thought maybe she'd start talking if she was as scared as I was. I didn't want to hurt her."

"I believe my client has said enough." Salk stood and walked over to Haywood. "He still has his rights and I only agreed to this so you could determine his mental state."

Dr. Quinn shifted in his seat, but the attorney's attention was on the obeservation room behind him. "Damn." Korsak looked at his companions. "Interview's over."

Jane pressed a button on the console in front of her, speaking to the patrolman. "Take him back to lockup."

They met Salk and Quinn in the hall. "My client won't be answering any more questions today, Detective."

"I get that." He glared at her for a moment then turned and walked away, bringing his phone up to his ear.

"Tact is not your strong point, Rizzoli."

"Look Quinn unless you have something important to tell me I don't need the commentary." She felt Maura's hand at her elbow, a silent plea for calm. Jane was unnerved and she didn't really have an explanation for it.

"How about this? Your suspect has a serious mental condition."

"He was showing symptoms of Capgras Syndrome." Quinn gave Maura an appraising look, nodding.

"Yes he was though there will have to be extensive tests to confirm it. It's rare, only about 3% of psychiatric patients develop it."

"What the hell is that?"

Maura turned to Jane, knowing the explanation may be better received from her. "It's a condition that can develop in people with diseases like Mr. Haywood. They will recognize faces, but they have no emotional connection."

"That doesn't make sense."

"When you look at someone you're close to, that you know, there's an emotional response." Jane nodded and motioned for Maura to get on with it. "Somehow he lost that connection. When he looked at his wife that response wasn't there, leading him to think she'd been replaced. To him it was the only explanation."

"Like I said, its very rare Detective, but incidents of violence aren't unheard of."

"So what now?"

Quinn raised his hands in surrender. "That is up to you. I will write up my findings, but I doubt they will help you in a criminal case."

"As far as I'm concerned he killed someone. It doesn't matter if he didn't believe it was his wife."

"That is between you and the courts."
