The crimson blood pooled beneath Margaret Whitmore's lifeless body as dawn's first light illuminated the mansion's marble foyer completely. Detective Sarah Chen stepped carefully around the evidence, her trained eyes cataloging every detail of this most perplexing crime scene. The victim lay sprawled at the bottom of the grand staircase, her emerald evening gown spread like expensive wings. No weapon was visible anywhere near the body, though the wound suggested something sharp had pierced her heart directly. Above them, the crystal chandelier swayed gently in the morning breeze from an open window on the second floor. Chen noticed the victim's diamond necklace remained untouched, eliminating robbery as the most obvious motive for this violent death. Footprints in the marble dust led in multiple directions, suggesting several people had been present during the fatal evening. The detective's partner arrived with the forensics team, their equipment ready to uncover secrets hidden within this luxurious tomb.
