The precinct, as her surrounding, was floating in the back of Detective Kate Beckett's mind she had her eyes closed at the moment with her lip tucked beneath her front teeth, she was trying to dance the crime scene. She opened her eyes for a minute or two and then closed them again walking the room in her mind with all the facts.

They had found out the name of the dancer, his name was Daniel Davis, age 24. He was a competitive ball room dancer, about to be married to his dance partner in about a month. He meant something to somebody. They had three suspects, his partner and soon to be fiancée who claimed to be at home alone sleeping, his ex-girlfriend of about three years, and his sister who stood to gain a lot of money if he wasn't able to get the inheritance, this of course including the dance school itself.

Looking at the murder board she stared and stared. All of them had opportunity, at least two had motive. But it didn't really make sense at all; sure the wound was a high heel and he was murdered with a scarf, they were missing something. She needed to go back.

"Castle! You coming?" she asked, yet somewhat demanded of him.

He started after her, on the way back to the crime scene. Once they were there he stood in the door way staring at her as she walked around the room with that furrowed brow trying to figure out just what had happened.

Kate was counting, she was trying to figure out what dance they were doing and trying to see if the wounds and the damages to the room would tell her. She was doing what Castle had taught her, she was finding the story. Sooner than she thought Castle had stepped in front of her and stolen her body, one hand on her waist, the other in her hand. Before she could put up a verbal or physical resistance, he said "Let's Dance!"

He spun her around the room, was this supposed to be fun? Kate wondered. Soon he had her against the wall, "And this is where the kissed violently, moments before the murder, Kate…"

"Castle, don't even think about it"

"Too late, already did" he whispered seductively, smiled back and then leaned in, he had her pinned against the wall, she couldn't move.

He only leaned in, leaving the rest of the distance to her. She leaned in, stopped right before his lips, looks straight into his eyes the leaned in a little more but turned her head going past his lips to his ear, "You wish" she said sliding down the glass mirror and exiting through his legs turning him around. They continued to dance. This could only get more interesting; soon Beckett had Castle on the ground heel against his back.

"So that is how it's done, thanks for the dance Castle"

"No problem, I have always wanted to pin you against the wall, and then you, you got me horizontal, what a step in our relationship." He smiled during his pause; she rolled her eyes as he continued, "So what would you call that? The dance, a Paso Doble or Tango?"

"Intense love fierce hate..."

"Kinda like us" Castle chimed in but Beckett ignored.

"I'm going to say the Tango, only at the end; she really did rip his heart out."
