The rain fell hard upon the cold pavement where the body lay silent under the flickering yellow streetlamp above them. Detective Miller stepped closer to the dark figure that was lying motionless in the pouring rain tonight all alone there. A single silver pocket watch lay open near the hand of the victim who had died very quickly indeed now. He knew this case would be difficult because there were no witnesses to see what happened here tonight at all. The wind howled loudly through the empty alleyway while the detective pulled his coat tighter around his cold shoulders now.
