The cold autumn rain lashed the small used bookstore window, as the first corpse slumped against the worn oak shelf. The trembling part-time clerk pressed shaking fingers against her lips to stifle a terrified gasp before grabbing her battered phone. A silver-haired detective in a frayed trench coat stepped through the rain-soaked door minutes later followed by his nervous partner. The detective knelt beside the body and spotted an old tiny brass key tucked beneath the victim’s scuffed leather shoe.
