Detective Arlo Vance found the dead body precisely at midnight in the dark, silent library of the old Henderson estate. A single bullet hole clearly marred the victim's pale forehead, but the deadly murder weapon was nowhere to be found. Moonlight streamed through the tall, broken window, and it finally illuminated scattered papers and a half-empty glass of amber brandy. The victim's frozen face showed sheer terror, yet the locked door suggested no possible escape for the cunning killer inside. A cryptic note clutched in the stiff, cold hand promised revenge for a long-forgotten, terrible betrayal from the distant past. Vance intuitively knew the butler had lied, but the widow's grief seemed utterly genuine and profoundly heartbreaking to everyone present. Everyone in the old house was a suspect, and each certainly had a motive for this brutal, calculated killing now.
