Chapter Twelve - The Apartment

The three of them stood in the doorway and looked into the apartment. Inside was the truth. All they had to do was find it.

"So, I'm Tina. You two can choose who you want to be." Catherine announced.

"I'll be the suspect," Caine said, "If that's alright with you, Grissom."

"It's fine."

"Okay, so I enter first," Catherine spoke as she walked into the room, "I reach here and turn round. Why?"

"Maybe because I walk in behind you. You hear me, turn to see what the noise is. I have a gun, and I back you into the bedroom," he smirked, a twinkle in his eyes.

"According to his story you had me pinned against the wall. Footprints lead to that wall."

Grissom backed her into the bedroom towards the far wall. All the way his eyes were fixed on hers. Lost in her gaze, he didn't realise they had reached the wall until her back hit it.

"Ow! Are you gonna really shoot me too?" she joked, knowing exactly why he hadn't been aware of the wall.

He was now standing only centimetres from her. She could feel each breath against her skin and there was that feeling again.

"Of course I'm not gonna shoot you."

"Good. So, you have a gun against my chest."

"The wound was about here," Grissom said softly as he positioned his hand where he imagined the gun would have been. His touch was so gentle. Catherine repeated her earlier thought, what was going on?

"Do you two want to be alone?" Horatio's voice broke her thought pattern. Catherine glared at him playfully. "I just thought that might have been what I said when I came in," he smiled.

"I doubt it," Catherine responded. "So you're in the room, so Grissom shoots me now..Wait!"

"Cath, I'm not gonna really shoot you."

"No.. That's it!" She looked into Grissom's eyes, as she tried to step away from the wall but found herself trapped, "Excuse me, please."

Slowly and reluctantly Grissom stepped backwards. Catherine smiled her thanks and turned round.

"There are no marks on this wall. If I was shot here then there would be blood, for starters."

"Maybe it wasn't this wall."

They looked around the room. The only wall with any blood on it was above the bed.

"He couldn't have had her pinned against that wall. They'd have been standing on the bed. And the blood wouldn't have spattered that way," Grissom observed.

"So that's proof that he lied. It's not proof that he killed her, but it's proof that he's hiding something. We-"

Catherine's phone rang. "Hello?. Right.Ah, excellent. Yeah.. Thanks, keep up the good work.". She hung up the phone. "That was Nick. They've found traces of Jackson's saliva in Tina's mouth, and vice versa."

"He could have kissed her. Forcing himself on her."

"That's true. They also found her fingerprints on the belt that he was wearing."

"She could have been trying to push him away."

"On the back of his belt, as if her hand was wrapped round it."

"Pulling him off?"

"Maybe. Let's see. Lucky you're wearing a belt today. Come here."

Catherine positioned herself against the wall again and Grissom happily stepped in front of her.

"Now put your gun back."

He re-positioned his hand.

"Let's see if I can reach the back of your belt."

Catherine reached her arms around Grissom trying to reach his belt. In order to wrap her hands round it, she had to pull him very close to her, until he was pressed right against her.

"Does this feel like a position you would let me get you into if you were attacking me?" She had a flirtatious smile on her face. She quickly checked it.

"It's a little uncomfortable holding a gun against you like this."

"Lose the gun," she said, her eyes once more meeting his.

He moved his hand from her chest.

"Now re-position yourself so you're more comfortable."

Horatio shook his head and laughed.

"You got a problem, Miami?" Cath called, looking over Grissom's shoulder.

"No not at all. I just think you are losing our bet."

"We didn't have a bet."

"Lucky for you."

Catherine was surprised away from their conversation by the feeling of Grissom's hand on her rear.

"Grissom!" she exclaimed, looking at him questioningly.

"Sorry, hand slipped," Grissom said, laughing as he stepped away from Catherine.

"Well, I think we've just established it's more likely they were in a friendly embrace than an acrimonious one."

"And what are you gonna do? Re-enact that in court?" Horatio smirked.

"No!" she emphasised, "We're gonna talk to our suspect. Once he knows that we know he lied, he'll crack."

"Are you sure?"

"Yeah. He's not a killer. He didn't do this for the sake of it, he did it because he was hurt, and jealous, and heart-broken."

"You sound like you're justifying it."

"No, definitely not. I'm just saying, he didn't plan this very meticulously. He just wanted revenge. He came up with his story after the fact. Thought we'd believe him because he was confessing to something."

"You seem to think you know him pretty well," Horatio said.

"I know what it's like to be cheated on. I was never driven to kill anyone though. Just to extreme hatred."

Horatio shook his head. "You didn't deserve that."

"I just married the wrong guy. We learn from our mistakes."

They proceeded out of the apartment and headed to the car.

"Do you think you'll ever marry again?" Horatio continued.

Catherine looked at him, surprised, "That depends if the right guy asks."

"Do you have anyone in mind?" he teased.

Catherine glared at him again and hit him gently on the arm.

"This case seems too simple," Grissom said, as if unaware of the conversation taking place next to him.

"Sometimes they are simple, Gil. This was jealous rage. Drives some people to do crazy things."

"Well, I wouldn't know about that."

"Come on, you've never been jealous?"

"I've never done anything crazy as a result."

Catherine smiled at his honesty, and although unsure of whether she actually wanted to know the answer, asked: "So, you have been jealous? When?"

"That's hardly an appropriate question, Catherine."

Catherine just smiled.

"Like you two have been sticking to appropriate behaviour tonight," Horatio said, just loud enough that Catherine could hear him.

She elbowed him in his side, and glared at him in a sideways glance. He just smirked.
