The rain fell hard on the deserted city streets tonight. Darkness shrouded the old mansion on the hillside slowly. Detective Jameson stood outside the mansion with his partner. He had received a cryptic message about the murder victim. The note was written on a plain white paper card. It said simply "Come alone" without any signature or name. Jameson felt a sense of unease as he approached door. The large oak door creaked as he pushed it slowly.
