The Mysterious Disappearance of Dorothy Arnold

In December 1910, 25-year-old Dorothy Arnold, heiress to a wealthy New York perfume fortune, stepped out for a routine shopping trip on Fifth Avenue and vanished into thin air. Educated at Bryn Mawr, dreaming of a writing career, secretly involved with an older man her family despised—she left no note, no body, no clues. Her prominent family delayed police involvement for weeks, fearing scandal, while Pinkerton detectives launched a massive transatlantic hunt with unlimited funds. Theories range from elopement to botched abortion, suicide, or foul play, but over a century later, the truth remains elusive.
