The rain drummed against the old mansion’s grimy windows. Fog curled through the garden like a ghost’s slow breath. Detective Mara Voss adjusted her damp coat carefully. A single candle flickered in the abandoned study’s corner. Footsteps echoed where no one should have walked tonight. The locked door creaked open without a touch from hands. Inside, a body lay sprawled near the shattered decanter. Bloodstains spelled a name no one recognized yet. Her flashlight trembled as she stepped closer to the scene. Something whispered her name from the shadows behind.
