The Disappearance of Dorothy Arnold

On the twelfth of December, 1910, a twenty-five-year-old woman left her home on East Seventy-Ninth Street in New York City and walked south down Fifth Avenue. She stopped at a bookstore. She met an old college friend on the sidewalk. She said she was going to walk through Central Park.She was never seen again.Dorothy Arnold was the daughter of a wealthy perfume importer, a Bryn Mawr graduate, an aspiring writer who had been rejected by McClure's Magazine three times. Her father did not call the police for six weeks. When he finally did, the story became the most famous missing-persons case in America.This is the story of what happened on Fifth Avenue that December afternoon. The six-week delay. The Pinkerton investigation. The four different theories her family privately held — and never agreed on. And why her father's will, written eighteen years later, simply stated as a matter of fact that his daughter was dead.A real case. A documented investigation. An unresolved disappearance.Episode Three of The Quiet Files.Sources: New York Times coverage, January 1911 onward; Pinkerton Detective Agency case file abstracts; the Joseph Cocchi connection (1921); Francis Arnold's last will and testament, 1928.
