Chapter 1

A/N: This is the first Miami fic that I've ever posted but I almost always write Miami ones, New York was just a fluke. This piece I actually turned in for the short story part unit in creative writing. The first six chapters at least.

Summary: Alone in the lab one night, Horatio and Calleigh give into temptation and kiss. Only problem, both are engaged to someone else? But when the unimaginable happens, will they survive? Or will the consequences be more than either of them can handle.

When the one you love is in love with someone else, don't you know its torture, I mean its living hell. - Rod Stewart, My Heart Can't Tell You No

The lab was quiet. It was these times in between shifts, when nightshift quite wasn't in yet and all of dayshift was gone…well, all but two.

Calleigh Duquesne was still in her ballistics lab. Sure, other criminalists used it, but she liked to think of it as her own private place, somewhere for her to come and find respite when she was running at full speed. It was also a place where she found herself doing a lot of soul searching.

Tonight was one of those times that she just needed to sort through her thoughts. Her excuse for staying late was a report that needed to be finished. It now lay open and incomplete on her desk, while she sat in her chair, lost in thought.

Horatio Caine was the other soul still hanging around. He sat up in his office, one floor above Calleigh, forcing himself to do some of his neglected paperwork but his head and heart just weren't in it.

So he sat and mused about his fiancé, and the future in general. He thought about how things were going to be now that he and his employee, Eric Delko, were going to be brother-in-law's. He thought about Tim and how much he missed him and about how hard Ryan was trying to fit in. And he thought about Calleigh and her up coming nuptials.

He was truly happy for her. She and John Hagen seemed to genuinely be in love with each other, despite their old issues. He knew Calleigh was going to make a wonderful wife. John was a very lucky guy.

But Horatio couldn't help but feel a little sad and even a bit jealous about the thing. Not that he didn't love his bride-to-be. Marisol was a beautiful, young, vibrant woman and he couldn't be happier about marrying her. But Calleigh had always meant more to him than he was willing to admit.

But what Horatio didn't know, was that the feeling was mutual. Calleigh had loved him from the day she met him, but he had made it clear to her that she wasn't his type and that Marisol was his true love.

She was happy for both them. They deserved each other. But it didn't soften the little ache she felt every time she saw them together. Calleigh loved John, there was no mistaking it. But her feelings for Horatio would always be hidden away deep in her heart.
