The rain began to fall on that cold October night. Detective Harris pulled his collar up and sighed so deeply inside. A single streetlamp flickered, struggling against the endless, swallowing dark. His shoes crunched on shattered glass from the old phone booth. The call had been a whisper, a single word, just "Come." Now he stood before the iron gates of the Ashford estate. They hung open like a broken jaw, inviting him to enter. He smelled the blood before he saw the crimson on marble. A woman's body lay beneath the grand piano, perfectly, terribly still. One pale hand pointed toward three words carved into the wood. Only two words remained legible in the dim and dying light. He leaned in close, holding his breath, and finally read them. "My heir."
