The rain hammered softly on the ancient mansion's windows, shadows dancing across wallpaper, as lightning briefly lit the silent, dark hall. Detective Harper arrived quietly, eyes scanning every corner, her coat dripping, gloves gripping her notebook tightly in cold air. In the grand foyer, a lifeless body lay face down, blood pooling beneath, suggesting violence erupted just moments before her arrival here. Guests gathered anxiously on the staircase, whispers spreading rapidly, as tension grew within the dimly lit, lavish room ambiance. The victim's name was Lord Frederick, known for secrets hidden beneath a polished, elegant surface, now shattered by sudden death.
