The story I'm trying to find basically goes like this:

undercover detective type about a TG that is living in a railroad shack on a trestle when he finds a bunch of suitcases and personal effects from a murdered woman then takes her place to solve her murder, she was an insurance co. investigator, looking into a bunch of deaths that end up being caused by a funeral home wacko and his crazy Post-op bitch that are running a sex club and killing people to make snuff films of the murders

Any help would be appreciated.

Thank you,
Rachel Anne
