The pilot episode was shot on location in a house in Country Club Park, Los Angeles, California, which serves as the haunted house and crime scene in the series. Designed and built in 1902 by Alfred Rosenheim, the president of the American Institute of Architects' Los Angeles chapter, the Tudor or Collegiate Gothic-style single family home was previously used as a convent. An adjoining chapel was removed from exterior shots using CGI. The series is filmed on sets that are an exact replica of the house. Details such as Louis Comfort Tiffany stained glass windows, and hammered bronze light fixtures, were re-created to preserve the look of the house.
