In a world where people die and come back as immortal mythical creatures (vampires, werewolves, zombies, gods etc.) the mortal Elmer Jones scratches out a living as a private investigator. An elf hires him for a case that starts out with a dumped husband stealing a wedding ring and eventually escalates into a plot to exterminate the entire human race. With the aid of his vampire assistant Val, Elmer must recover the ring, decipher its meaning, and save the world. All in a day’s work for the Last Living Detective.
