LAISSEZ LES BLOOD TEMPS ROULER
New Orleans, 1978. A city where the world’s oldest profession always has a new trick up its skirt and guys who flash enough cash can indulge every kink. But there’s a fancy new john in town with a taste for expensive cologne, a lust for evil pleasures, and an infernal devotion to an ancient goddess of Aztec butchery. As the gutters of the French Quarter run red with viscera, a tattered pair of homicide cops and a torn lesbian medical examiner must untangle the entrails that lead to an altar of carnage. With Fat Tuesday fast approaching and a pious psycho’s whore-gore gumbo reaching a boil, two hallowed traditions – one festive, the other fiendish – are ready to collide.
