Books like The Bungalow Mystery

The book starts off with heart pounding action, as Nancy and her friend Helen are caught out on the lake in a thunderstorm. Will they reach the shore through the blowing winds and treacherous waves? Luckily, a young gal, Laura, hears Nancy's cries for help and rescues the two. After introductions are made, Laura rather cryptically responds that she may need Nancy's help some day soon. What mystery will find Nancy tracking down clues? Another sound mystery in the series. Love how each chapter ends on a suspenseful note. Predictable but fun.
