The rain-soaked manor creaked as the night unfolded quietly deeply. Inside, an old portrait stared, its eyes haunting the hallway. A sudden scream pierced the silence, echoing through marble corridors. The butler froze, clutching a silver pocket watch in silence. The guests stared, their faces pale under flickering chandeliers above. At the center, a body lay, crimson spreading across floor. The detective arrived, his coat dripping, eyes scanning everything silently.
