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 overcoat carefully. A single candle flickered in the abandoned study’s darkness. Footsteps echoed where no one should have walked recently. The air smelled of lavender and something far more sinister. A letter lay open on the desk, ink still wet. *"Meet me here—tonight,"* the words whispered a warning. Mara’s fingers brushed the page, feeling residue cold. Beyond the glass, a shadow moved too fast to see.
