Fog swallowed the cobblestone street whole. Detective Black’s car crept slowly forward. A call had come in late. A scream, then a dead line. The old Grayson house loomed. A single light burned inside. The heavy oak door stood ajar. Black pushed it open slowly. The grand foyer was deathly still. A clock ticked in the silence. Black drew his service revolver cautiously. Something shimmered on the marble floor. A single, perfect pearl lay there. It led towards the main study. The study door was also open. A body lay on the rug. Lady Eleanor Grayson stared upwards, unseeing. A dagger protruded from her chest. The handle was ornate, polished silver. No other soul was present. The large window stood wide open. Cold night air whispered softly inside. It carried the scent of rain. Detective Black closed his weary eyes. He counted five distinct pearl droplets. They formed a trail leading out. But the window opened onto nothing. Just a long, dark, terrible drop. This was no simple robbery. This was a very careful murder.
