The Hidden Staircase

The second Nancy Drew mystery plunges the teen sleuth into a genuinely unsettling case at a decaying country estate. When elderly sisters Rosemary and Floretta Turnbull beg for help with what they believe are supernatural visitations, Nancy doesn't believe in ghosts. But the sounds in the night, the moving shadows, and the centuries-old house with its locked rooms and whispered secrets make a believer out of anyone. Her investigation leads her down a hidden staircase that the Turnbulls didn't even know existed, a secret passage that reveals the truth behind the hauntings is far more human, and far more dangerous, than any ghost. Nancy must race against time to unmask a villain hiding in plain sight before someone else disappears into the mansion's dark past.
