The old mansion loomed silently in moonlight. Dark shadows stretched across the cobblestone path. A single gas lamp flickered weakly outside. Footsteps crunched softly on the gravel drive. Someone had arrived at the abandoned estate. The front door stood ajar, creaking open. A chill wind whispered through empty hallways. Footprints led deeper into the decaying home. A single glove lay discarded near the stairs. The air smelled of damp and something darker. A distant scream echoed through the night. The intruder’s flashlight beam cut through the gloom. A body lay motionless on the floor. Blood pooled beneath the victim’s head. The killer had left no trace behind.
