Cold rain fell heavily upon the dark and empty street. Detective Miller knelt beside the lifeless body lying there. Blood pooled slowly beneath the heavy oak front door. A shattered pocket watch rested near his bloody hand. Midnight had arrived just before the fatal strike occurred. No footprints disturbed the fresh mud surrounding the garden. Someone had planned this brutal murder very carefully tonight.
