CSI: Beacon Hills AU. Sheriff Stilniski heads the force and Derek’s one of his broody “lone wolf” detectives (ha!). Stiles and Scott work in the lab (when they’re not getting on Derek’s very last nerve) and Lydia’s the medical examiner.
Scott is all dirty because Stiles somehow managed to talk him into being the one to comb through three dumpsters worth of trash looking for evidence. :D
