The rain drummed relentlessly against the foggy windows of Blackwood Manor tonight, twelve chimes echoing from the grandfather clock. Thick velvet curtains swayed slightly despite the locked windows and sealed doors in the dimly lit study. A single candelabra flickered, casting eerie shadows across the bloodstained contract lying on the mahogany desk. The victim’s glassy eyes stared unseeingly upward, his throat slit precisely beneath the dim light’s cruel glow.
