Dark shadows danced across the grand library walls where a lifeless body lay sprawled upon the cold marble floor below. Detective Arthur Vance stepped carefully over the broken shards of glass to examine the truly gruesome scene waiting for him. A silver letter opener protruded from the chest of the victim while dark blood pooled on the Persian rug beneath. He noticed a single red feather resting gently near the rigid hand of the recently deceased wealthy old man today. Someone had clearly searched the mahogany desk drawers before fleeing into the stormy night without leaving any visible footprints behind. Vance knew immediately that finding this elusive killer would require every ounce of his vast experience in solving brutal murders.
