The clock struck dead midnight. A scream pierced the night. Cold wind howled through trees. Detective Morgan surveyed the scene. Blood stained the marble floor. The body lay quite still. Her eyes stared without seeing. Broken glass surrounded the corpse. A knife glinted close by. The victim's name: Elizabeth Blackwood. Wealthy heiress to vast fortune. Someone clearly wanted her dead. Morgan noticed strange purple powder. The butler discovered her first. His alibi seemed rather weak. Five suspects resided this night. Each harbored different dark secrets. Each possessed convincing possible motives. Rain began tapping window panes. This murder would challenge Morgan. Who killed Elizabeth that night?
