I'm trying to write a short detective story (maybe a series, who knows?) taking place in my fictional world with magic and such. The story will feature a meeting between two detectives. Amita Frost, A short woman well versed in a variety of things (the Goren or Logan of the team (uh, Law and Order: CI reference)), and Bragen Hollander, a tall sharp eyed man with the kind of odd way of thinking that's quite helpful, but has a hot streak and a bit of cynicism (Stabler, Munch, Briscoe kinda guy (More L&O)). Unfortunately, I can't think of a good murder! There's no real reason a train room would be locked, so that's out, and you usually wouldn't know anyone on a train (and therefore no motive). That also get's rid of another idea: An ice cast of a knife belonging to someone else, to frame the other person. also, I can't think of a way to actually slow time of death, with high temperature the body heat isn't lost, but there's still rigor, isn't there? And being active before a death would speed up the rigor, making it seem like they've been dead longer.
