Heavy rain beat against the dark glass while Detective Vance stared at the lifeless body on the expensive Persian rug. Crimson blood pooled slowly around her shattered head, completely staining the pale silk dress she wore for the gala event. A sharp silver letter opener lay inches from her right hand, catching the dim glow of the flickering desk lamp. Careless footprints covered in dark mud trailed across the pristine floorboards toward the slightly open window in the very back. Vance crouched low, carefully observing a torn piece of green paper clutched tightly within the dead fingers of the victim. Sudden thunder roared angrily outside, masking the subtle sound of a floorboard creaking in the shadows behind his tense back. He drew his trusty revolver from his holster, realizing instantly that the brutal killer had never left the sprawling mansion.
