Heavy rain battered the tall gothic windows of Blackwood Manor while thunder shook the ancient floorboards beneath my muddy boots. Lord Arthur lay motionless beside the grand fireplace with a silver letter opener buried deep inside his cold, silent chest. Crimson blood stained the expensive Persian rug and pooled slowly around a shattered crystal glass smelling faintly of bitter almonds. Five terrified dinner guests stood huddled near the heavy oak doors while watching me examine the gruesome crime scene silently. Since every exit was bolted from within, the ruthless murderer was undeniably standing among those five pale faces right now. I pulled out my worn leather notebook and prepared to uncover every dark secret buried within this cursed family estate.
