The rain fell hard against the old mansion's tall windows. Inside, the detective studied the body on the marble floor. Blood pooled beneath the victim's expensive red silk evening gown. A broken crystal vase lay scattered near the front doorway. Someone had left through the garden entrance rather too quickly. Thunder crashed outside, masking any sounds of the fierce struggle. The butler stood trembling in the darkened corner by himself. "Tell me exactly what you saw tonight," he finally demanded. Shadows danced across the walls from the many flickering candles. Murder had come to visit this wealthy family here tonight.
