The rain fell hard upon the old mansion while thunder cracked loudly above the dark and silent night sky overhead. Inside the library a single body lay still upon the expensive rug near the cold and empty fireplace hearth below. Detective Miller stepped carefully around the blood stains on the floor without touching anything useful for the future case work. A broken pocket watch rested near the right hand of the victim showing the exact time of death quite clearly. The killer was surely still inside the house hiding within the shadows waiting for the police to leave the scene.
