The Papen County Historical Society Museum is a source of local history and was helpful in at least two of Emerson Cod's recorded investigations. In "Pigeon", Emerson, Ned, and Chuck went to the museum looking for information on the VonRoenn Windmill, to track down a killer and a buried treasure. The killer in question, Lefty Lem, had already been to the museum for the same information, according to the Curator. She told the trio that the Windmill had been retired and sent to N.A.R.M., the National Area of Retired Mills.
