Imogene Poplar, Private Eye, is on a hot case. Her friend Oliver K. Woodman is missing, and she's tracking him across the glorious US of A. A baseball game in Green River, a rodeo in Seattle, a razzmatazz jazz blow in Chicago—there are clues and adventures in every city. But Imogene, like Oliver, is made of wood, so she needs help getting around. Friendly folks of all sorts guide her from South Carolina clear out to Alaska! Where will Oliver's trail lead Imogene next? Read the letters. Follow the map. Then see if you can guess the elusive wooden man's next move. Imogene Poplar, a private investigator made of wood, is sent by a reporter and Tameka's Uncle Ray in search of the missing Oliver K. Woodman, and her journey is related through the letters and postcards of those she meets along the way.
