The old grandfather clock in the hallway had just finished striking the hour of midnight when someone screamed loudly upstairs. Rain lashed against the tall windows of Blackwood Manor, drowning out almost any other sound from the upper floor above. Detective Eleanor Vance stepped out of her car on the wet gravel drive and looked up at the dark house. A uniformed officer met her at the heavy front door and then led her inside without speaking a single word. The body of the wealthy Lord Blackwood lay sprawled across the cold polished floor of his vast private grand library. A shattered crystal glass rested near his outstretched hand, its ruby contents already staining the ivory rug a deep crimson. Eleanor knelt beside the lifeless cold body and noticed a faint odd smell of bitter almonds lingering in the air. Someone had poisoned the lord during his final toast, and every guest in the house was now a possible suspect.
