Marcy

American Horror Story
Marcy was a realtor from California. She sold the Harmon family a large mansion with a haunted past. Known as the "Murder House", it had been the site of numerous grisly murders for the past several decades, but Marcy only informed the Harmons of the most recent tragedy. When things became too difficult, Vivien Harmon demanded that Marcy put the house back on the market, instructing her to do everything she could to make it sellable. Following the deaths of the Harmons, Marcy then sold the house to the Ramos family. The ghosts of the Harmon family remained in the house and scared the Ramos family away so that they would not be tormented by the more malign spirits inhabiting the house.
