CSI returns with an all-new episode tonight, and it's one full of unusual killers. Or, at least, unusual motives.

For one, Langston is still out looking for Dr. Jekyll, who turns out isn't necessarily into tying up a dead person's guts. I mean, the last time he struck, he performed a delicate operation on someone sleeping, and just that! Last time we left they were a bit closer (just a bit) to identifying who the guy is, but of course, it's gotta take a while.

The more urgent case tonight involves the murder of two beautiful women in a Las Vegas hotel. At first inspection, nothing out of the ordinary, perhaps until you realize that, well, something odd is up with the killer. Well, there really aren't much clues--method or motive or just plain unusual--but it should be a bit freaky. Just a bit.

CSI returns tonight with a new episode from 9pm on Fox. The photos are below, and there aren't much, really. But still.
