While setting coins on the train tracks, letting passing trains flatten them, Maggie and her friends are startled when a man, dressed in rags, races from a deserted box car into the woods. Wondering if he was homeless, they decide to follow him and see if he needs help, noticing a fifty-dollar bill on the ground. Why would a homeless man have a fifty-dollar bill?
Moving through the woods, trying to track him, they come to a boarded-up train tunnel wedged into the hillside. Pulling some of the loose boards free, they explore inside, the tunnel damp and dark. While exploring, they stumble upon three empty, half-buried Stillwater Bank bags.
But that's not all.
They notice a spray-painted mark glowing on the wall and find a silver necklace along the tracks. Maggie remembers one of the Darke County Fair workers wearing the exact same necklace. Was he involved? Where was the homeless man? What did the mark on the wall mean? And more importantly, where was the money?
Compulsively readable, Mad Maggie Dupree and The Darke County Fair is the fourth book in the Mad Maggie Dupree series. Looking into yet another harrowing mystery, the headstrong, slingshot toting redhead leaves an indelible mark with each mistake and every triumph as she and her friends look out for each other while always seeking the truth.
