The old mansion loomed darkly tonight. Rain pattered softly against the windows. A single candle flickered weakly inside. Footsteps echoed down the creaking hallway. The door swung open with a groan. Silence stretched uncomfortably between them all. A gasp escaped from the gathered crowd. Then, the body lay motionless on floor. Blood pooled darkly beneath the victim. Shock froze every single person there.
