The stormy night was shattered by a dreadful, echoing scream. Detective Monroe arrived at the mansion, his coat completely soaked. The butler, pale and trembling, led him to the library. The wealthy owner lay dead on the cold library floor. A broken vase lay nearby, completely shattered into many pieces. Blood stained the Persian rug in a dark, spreading pool. Monroe knelt down, examining the wound on the victim's head. "Who found him?" he asked the butler, his voice low. "The maid, sir, just before you arrived," the butler whispered. "Take me to her right now," Monroe said, standing up.
