Heavy rain pounded against the shattered glass of the window. Detective Vance stepped slowly into the dark and silent room. A pale hand extended from beneath the heavy velvet curtain. Blood stained the expensive white carpet with a crimson circle. He knelt beside the lifeless body of the wealthy banker. A silver dagger rested firmly between the cold shoulder blades. Arthur Pendelton had many enemies within this quiet coastal town. Vance noticed a torn photograph clutched inside the frozen fingers. Suddenly, a floorboard creaked somewhere in the hallway behind him. The killer was clearly still waiting inside the shadowed house. He slowly drew his loaded pistol from his leather holster. Lightning flashed brightly across the stormy midnight sky above them. Footsteps echoed loudly as a dark figure dashed away quickly. The greatest mystery of his long career had just begun.
