Frost greeted them when Jane parked at the curb. He nodded at Maura with a smile as she came around the front of the car. "Welcome back, Dr. Isles."

"Thank you Dectective Frost."

"What do we have?"

"Multiple stab wounds. Victim is Sara Haywood. Her father found her this morning along with her husband."

"Was he dead too?"

Frost shook his head with a sad look. "He's in custody. He attacker her father as soon as he came in. He managed to fight him off and call us."

Frost pointed toward a patrol car. "We're sending him to processing now."

He didn't look the type. He was a middle aged man, slightly out of shape, and staring off into the distance. He didn't even seem to notice the activity around him. It was like shock had taken over.

Jane didn't need to remind herself that "the type" was almost never what you expected. "Ok, Frost. Have you questioned the victim's father?"

"Korsak's with him now. I thought you and the Doc would want to see the body."

"Lead on."

They followed Frost into the house, slipping on the gloves and booties offered. Frost looked at his notebook, then started filling them in. "Cecil Johnson, the victim's father, came by early this morning. She called him yesterday about a problem with the garbage disposal. He called it a "dad fix." Anyway he let himself in and found his daughter on the floor and our suspect, Sam Haywood, sitting in the corner covered in blood, holding the knife."

Sara Haywood came into view as they entered the kitchen. She was laid out on the tile floor beside the table. Maura knelt beside the body beginning her exam. Frost kept up his monolog. "Mr. Johnson says our suspect saw him and attacked. He was able to fight him off and subdue him until we got here."

Jane looked around the room. Except for the over turned chairs and blood stains it could have been any other room in any other house. It was normal, almost peaceful, until now. "Any idea of a timeline?"

Frost shrugged, flipping back through his notes. "Mr. Johnson spoke to his daughter at five last night. He got here this morning at 6:30. He said she mentioned going out for drinks with friends, then coming home for dinner."

Maura looked up from the floor. "Liver temp suggests time of death around ten hours ago. I'll know more once I get her back to the morgue. Where is the weapon?"

"Your techs have already logged it for evidence."

The doctor motioned to the coroner's assistants to start loading the body. Looking at her watch, she walked over to Jane and Frost. "I'll start the autopsy at nine. I should have some results by noon."

Flashing Jane a smile, she followed the assistants out. The detective turned to see Frost giving her an unidentifiable look. "What?"

"Oh nothing. You're both looking very relaxed this morning."

Jane rolled her eyes and turned to finish processing the scene. "We had a relaxing evening."

Frost followed her now grinning wildly. "Did you tell her you wussed out and stayed at her house all week?"

Shooting him a mean look, she stopped. "None of your business. But yes."

He laughed. "Ok, partner I'll drop it."

"Let's just get this finished."

R&I

Korsak slumped down at his desk. "Haywood is in Interrogation when you're ready Jane."

"Is Mr. Johnson still here?"

"Downstairs with his wife."

She nodded and headed for the interrogation room. They'd found several presciptions at the Haywood house. All drugs used to treat bi-polar disorder, and that according to Maura were commonly used. All of them were prescribed to Samuel Haywood. M. Johnson had told them their suspect had been in treatment for months, and that he was starting to show progress. Enough that his doctor had thought him capable to resume his work as an accountant. Jane had called the man and he was now on his way.

She opened the door and entered with Frost behind her. Sam Haywood was agitated when he saw them.

"Where is my wife?"

Jane's eyebrows rose. "Do you remember what happened last night Mr. Haywood?"

He calmed for a moment and dropped his head. "That wasn't my wife. That was an intruder. Is that why I'm here?"

Sharing a look with Frost she said the next carefully. "Mr. Haywood your wife was killed last night in your home."

He became furious. "That wasn't my wife! It was an imposter, they took her and replaced her!"

"Who took her?"

"I don't know! That's your job, why aren't you out there looking?"

"Mr. Haywood, your wife's father identified the body." Jane was beginning to realize this might be more than a psychotic break.

"He's lying! He's one of them!" Haywood jumped up from his chair and grabbed Jane's wrist, squeezing hard.

Frost was just as fast, grabbing him and pinning him to the table. "Let her go Mr. Haywood."

He struggled, nearly throwing Frost off. "My wife is out there! Why aren't you listening to me?"

Two patrolmen came in to help and Jane backed away from the table. She knew Korsak was watching and looked at the mirrored glass. This just got a whole lot more complicated.
