The Devil Bat

Swamp mist clings to the lab’s rusted stills, autumn 1940. A chemist in a soiled coat pours violet serum into vials labeled *Heath & Morton Lotion*. Bat wings scrape glass as headlines pile on a newsroom desk. This is Bela Lugosi doing mad science on a shoestring—perfect for a stormy night with the lights out.
