I don't write CSI well or often but I do have a few ideas bouncing around in my twisted little head. Here's one.

Someone from Catherine's past decideds to destroy her reputation by making them belive she's using again. Just when things get at its worst, Catherine gets framed for murder.

Must have:

1. Catherine insists she's not using but fails the drug test.
2. References to her stripping days.
3. Grissom doubting Catherine's innocence.

Must have at least one of the following.

1. Greg and Warrick are the only one's who belive Catherine is not using and not a killer. (At least at first, we need conflict)
2. The line, "Just when things can't get any weirder, you say something like that."
3. The line, "Between me and Warrick, we have enough street cred to buy most of the strip."
4. The line, "Science sometimes lies. I never have. At least not to you."

Please someone write me a story.
