The rain hammered relentlessly against the tall windows of Blackwood Manor as Detective Sarah Chen stepped carefully over the threshold. Inside, the body of Lord Blackwood lay sprawled across the Persian rug, a silver letter opener protruding from his chest. His pale eyes stared blankly at the ornate ceiling, frozen forever in an expression of pure, unadulterated terror and surprise. The elderly housekeeper, Mrs. Whitmore, had discovered him at dawn, her screams echoing through the empty halls of the estate. Now the entire room buzzed with activity as forensic technicians photographed every surface and collected evidence with meticulous, careful precision. Sarah knelt beside the cooling corpse, noting the defensive wounds on his hands and the faint smell of bitter almonds. Someone had clearly poisoned him first, then stabbed him twice, which meant the killer wanted him dead with absolute certainty. Her partner, Detective James Rodriguez, appeared suddenly in the doorway, his face pale and a notepad clutched tightly in hand. "We've got six suspects, Sarah," he said quietly, "and every single one of them had reason to kill him tonight." Sarah looked down at the body once more, sensing that this case would test every skill she had ever learned.
