Rain hammered the mansion windows as Detective Mara stepped inside. The butler met her with a trembling, pale, thin hand. A body lay beneath the chandelier in the grand foyer. Blood pooled around the victim's head on the cold marble. The victim wore silk and held a broken crystal glass. Mara knelt beside him and checked for any faint pulse. None remained, so she studied the strange red symbol nearby. It was painted freshly upon the locked library door today. The butler whispered that no one had entered or left. Mara noticed his left cufflink was missing one small ruby.
