Cold rain lashed the old gabled slate of Blackthorn Manor. James the elderly butler rounded the heavy oak library doorframe. Silver candelabras cast long trembling shadows on cold rough stone. The house’s lord lay sprawled across the wide mahogany desk. A sharp letter opener jutted from his blood-soaked left temple. James fumbled his pocket watch, breath catching in his throat. The room’s oak door remained locked only from the inside. A single white rose petal drifted past James’s shaking boots. No guest had brought white flowers to the weekend’s gala.
