"We checked the scene, but there wasn't a whole lot to go on." Nick sighed. "A lot of fingerprints, but most of them will probably come back to the hospital staff."

"Well, tell Mandy to put a rush on it anyway. We might get lucky." Cath answered half-heartedly, her attention still mainly drawn to the list of potential suspects. Most of them were sexual offenders and all of them had a history of violence. Quite frankly, Sara was a very lucky girl to have walked away from the attack with so few injuries.

"Any word on when Sara will be back?" Warrick asked, fidgeting awkwardly with the folder in his hands. For the first time, Catherine took her glasses off and met their gaze.

"She's still pretty shaken up by it all. To be honest, I think she could do with a proper break from work, but I doubt she'll go for that." She exhaled. "If I can keep her off for a week, I think we can call that an achievement."

"Yeah, I'll say." Nick chuckled. "So, have you spoken to Grissom yet?"

"No, he keeps trying to call me but I haven't answered. I don't have anything much to say to him at the moment."

The boys shared a knowing look between themselves which went completely unnoticed by the stressed-out supervisor.

"Hey Cath," Nick cleared his throat softly. "Don't go too hard on him. He never meant to let this happen."

"No." She agreed curtly. "He never does. But he was responsible for her welfare and he let her down."

Deciding that the conversation was over, she gathered her papers into an untidy pile and stalked out of the room, leaving a cold chill in her wake.

"Well," Warrick nodded slowly. "I think it's safe to say that Grissom's toast."

Seeking refuge in her office, Catherine put her glasses on and resumed her laborious reading; but her peace and quiet was not to last very long.

The abrupt entrance was only briefly heralded by the sound of angry footsteps clicking towards the lab.

"What the hell is your problem?"

Catherine jumped as two hands slammed onto her desk and she found herself staring up into the ice cold eyes of Belinda Bell.

"I'm sorry?" She queried, standing up and taking her glasses off once again.

"I know that you didn't like me seeing Sara, but don't you think that this is too far?"

"I don't know what you're talking about." Cath frowned, holding up her hands.

Belinda took a step around the desk, bringing them closer together. Her eyes narrowed to slits, but the venom in her voice never faltered.

"I've been suspended." She spat. "The hospital found out about my relationship with Sara – apparently someone put in an anonymous complaint."

"And by someone, you mean me?" Catherine assumed, folding her arms defensively.

"Well, who else?" Belinda threw her hands up. "They're carrying out an internal investigation and if I'm found to have breached my position of trust, I could have my nursing licence revoked!"

Catherine pursed her lips and jutted out her chin, saying nothing. After a tense stand-off, Belinda choked out a laugh.

"Of course you don't care; why would you?" She shook her head, taking a step back. "You've had it in for me ever since you first found out about me and Sara. Well, congratulations, mission accomplished - my career is over!"

Turning on her heel, she made it as far as the door before Catherine's calm voice halted her in her tracks.

"Sara's fine ... in case you were wondering."

Belinda turned slowly to face her, her expression unreadable, and lowered her voice.

"You have no idea what this is going to do to her." She offered coolly. "You think you're helping her, but you've just made things worse."

She hadn't realised it, but she had been stirring her coffee for so long that it had gone cold.

She had assumed that Catherine was the one who reported her because, quite frankly, it made the most sense. But the more she thought about it, the more she started to reconsider. The CSI may have covered it well, but initially she had appeared surprised to find out about her suspension.

Which now led her to question who else could have reported her. As far she as was aware, nobody else from the lab knew about it. And she couldn't imagine Sara would drop her in it; that wasn't her style. She hadn't told anyone about the illicit relationship, so it must have come from someone who Sara had told.

And while she sat pondering the matter, stirring her cold coffee, a possible solution to her puzzle walked through the door.

The boys didn't even notice her at first – why would they? She had never so much as had a conversation with them beyond a casual 'hi' in the corridor. But she recognised them instantly; Nick Stokes and Greg Sanders, two of Sara's friends and colleagues.

They chatted amicably as they placed their orders, before mooching through the diner to find a booth. But as they walked past her table, one of them caught her eye and seemed to pause for a moment. The look on his face was hard to decipher, but it certainly was not an expression of familiar warmth.

Finally, he continued past without a word and sat down with his back to her.

It was only a fleeting moment, but it was enough to make her re-think her earlier assumptions.

As far as she was aware, Catherine was the only person in the lab who knew about her relationship with Sara. But what if she was wrong? What if Sara had told someone else?

If so, then there was only one person Sara was close enough to, one person she was likely to confide such person information in.

Greg Sanders.

As she sat at the red light, drumming her fingertips on the steering wheel impatiently, Catherine's mind worked through her earlier encounter with Belinda.

The nurse was right about one thing; she couldn't exactly claim to be sad that she had been suspended.

Still, she wasn't the one who had reported her; and it wouldn't have been Sara – the brunette was hardly in the right frame of mind yesterday to be making such important decisions.

But who else knew about it? Sara had already assured her that she hadn't told Grissom or the boys, and Catherine sure as hell hadn't told them. In fact, she hadn't told anyone.

Except for one person...
