The rain poured relentlessly upon the old abandoned Thornfield Manor. Detective Morgan surveyed the scene with his experienced, weary eyes. A body lay sprawled across the mahogany floor, blood pooling. The victim's hand clutched a crumpled note written in code. Thunder crashed outside as the grandfather clock struck midnight precisely. "Time of death, approximately three hours ago," stated Dr. Wilson. Morgan noticed muddy footprints leading away from the corpse deliberately. The victim was Eliza Blackwood, heiress to the Blackwood fortune. Her jewels remained untouched, ruling out a simple robbery motive. A silver letter opener protruded from between her shoulder blades. Morgan examined the murder weapon, noting the ornate family crest. "Whoever did this was invited here," he concluded with certainty. Five suspects waited downstairs, each with secrets worth killing for. The storm intensified, ensuring no one would leave until morning. Morgan opened his notebook, preparing to unravel deadly family lies.
