The body lay near stairs. Rain tapped against the window. Detective Mara Cole arrived alone. She knelt beside the corpse. Blood pooled beneath the head. No weapon sat in sight. Her flashlight swept the room. A broken clock read midnight. Someone had locked the door. She pulled on latex gloves. The victim's eyes were open. His hand clutched a key. Mara frowned at the message. The dust said, "Ask Alice." She lifted the old receiver. A voice whispered, "She's awake."
