From the introduction:
Nitrate City is an urban jungle of raw nerves and heightened emotions, where mad scientists, chalk-skinned vampires, werewolves, swamp monsters, and the reanimated dead exist alongside—and as—private detectives, femme fatales, Don Juans, and gun-toting gangsters of every stripe. It’s a city whose heart pounds to the rhythms of black magic and mad science, noir-fueled crime and political corruption. It’s a place where the boundaries that separate monster from mobster and cops from living corpse blur with every flicker of the lamplight. It’s a place where everyone has a secret to keep.
