My short story Valentine Vampire is a romantic version of the Chicago Valentine’s Day Massacre, result of a rivalry between the gangs of Al Capone and Bugs Moran.
My connection to the historical event is this. My grandmother lived in a house about a block and a half from the building where this occurred. She was on the second floor near a window when the guns went off in what was usually a quiet, peaceful neighborhood. But it was Chicago. And even back then, no one ran out in the street at the sound of gunshots.
