The body lay sprawled across the mahogany desk, blood pooling beneath the antique letter opener that glinted in dim light. Detective Mara Voss stepped through the doorway, her heels clicking against marble floors as rain drummed on the study windows. She noted the overturned chair, the shattered crystal decanter, and the single red rose placed carefully on the victim's chest. Three witnesses huddled in the hallway, whispering theories about inheritance while the butler polished an already immaculate silver serving tray. The dead man's eyes stared upward, frozen in an expression that looked almost like surprise mixed with something like recognition. Mara knelt beside the corpse, snapping on latex gloves before lifting the rose to examine its unusually long thorny stem. Outside, thunder cracked violently as the lights flickered once, plunging the mansion into darkness for one breathless and terrifying moment. When the generator hummed back to life, Mara noticed the rose had vanished from her gloved palm into thin air.
