The rain battered against the windows of the mansion. Detective Cole stepped under the yellow police tape line. Officers huddled near the garden where they found her. Her body lay still beneath the old weeping willow. Blood stained the white gown she wore that night. "Time of death was around midnight," the coroner said. Cole knelt beside the body, searching for any clues. A single red rose rested clutched in her hand. Strange symbols were carved deeply into the tree bark. "Who would do this to poor Ms. Wainwright?" someone asked. Cole noticed footprints leading away through the muddy garden. The guests inside the mansion all had solid alibis. Yet someone among them was surely lying through their teeth. The detective stood up and walked toward the house. Inside, candles flickered as a storm approached from the west. A scream suddenly echoed through the darkened hallway upstairs. Cole rushed inside, his hand resting on his weapon. Another body lay sprawled across the master bedroom floor. The killer was still here, hiding somewhere among them. This night would prove longer than Cole had expected.
