Episode Description

On a crisp winter day in 1910, a 25-year-old New York socialite left her family’s Upper East Side home to buy a new evening gown, and vanished without a trace. Over a century later, Dorothy Arnold’s disappearance remains one of New York’s greatest unsolved mysteries and its oldest missing persons case. Over the decades, there have been many theories about Dorothy’s fate; everything from secret elopements and amnesia to botched surgeries and buried bodies. But despite widespread publicity, Dorothy has never been found. Did something tragic happen to her on that cold December day, or did Dorothy Arnold simply choose a different path for herself?
