Dorothy Arnold: The Wave on Fifth Avenue (1910)

Midnight Mystery Archive

Show Notes

On December 12, 1910, Dorothy Arnold, a 25-year-old Bryn Mawr graduate and aspiring writer from a prominent Manhattan family, left home to go shopping. A little before two that afternoon, she spoke with a friend outside Brentano’s bookstore on Fifth Avenue. The friend waved goodbye from the corner. No one has been documented seeing Dorothy Arnold since. Her family waited roughly six weeks to go public. The search that followed spanned Pinkerton agents, transatlantic cables, a confrontation in Florence, and the dragging of Central Park ponds. Over the decades, five explanations have survived, and a handful of false leads, hoaxes and claims have come and gone. This episode walks through the documented record, presents the evidence for and against each theory without ranking them, and flags the places where historical sources disagree. Sources: Allen Churchill, “The Girl Who Never Came Back,” American Heritage (1960); Rosemary Counter, National Geographic (2024); The Charley Project; period newspaper reporting. The Charley Project maintains the public case file for Dorothy Arnold and thousands of other missing persons: charleyproject.org Midnight Mystery Archive is a research-driven show with an evidence-first, no-speculation standard. New episodes bi-weekly.

This is the final episode of the Midnight Mystery Archive. In Part 1, we covered who Kerryn Tate was and what happened on December 29, 1979: a 22-year-old woman hitchhiking southeast of Perth, a deliberately set fire, a body found in bushland near the Canning Dam catchment. 45 years of the case staying open. And the biological evidence recovered at the scene in 1979 that police kept, year after year, waiting for science to catch up. This is Part 2. The science caught up. In 2023, Western Australia Police handed that biological evidence to their investigative genetic genealogy team — a unit WA Police has described as leading the world in this methodology. The team uploaded the DNA to a public genealogy database, the same kind people use to find their cousins and trace their ancestry. The database returned genetic matches: not to the offender, but to their relatives. From those relatives, the team built a family tree. Ten thousand people. Constructed from birth certificates, death records, census data, genealogical archives, and genetic connections. Every branch narrowed the pool. At the end of that tree was one name. Terrence John Fisher. Fisher had died in 2000 at the age of 50, of natural causes, while living with his father in Manning, Perth. He had never been charged. His name had never appeared in the original 1979 investigation. He had lived his life — working as a carpenter with the WA Public Works Department, sailing at the Fremantle Sailing Club, frequenting pubs in Carlisle and Victoria Park and Manning — and had died without ever facing a single consequence. When WA Police named Fisher publicly in March 2025, they also said this: if Fisher were alive, he would be a person of interest in the deaths of two other Western Australian women — Barbara Western, murdered in 1986, and Carrie Turner, murdered in 1991. That is not an accusation. It is a statement of investigative significance. Police do not name dead men as persons of interest in other murders without a reason. The reason is not publicly detailed. What it means is that investigators looked at those three deaths and saw something worth pursuing. Terrence John Fisher cannot be arrested. He cannot be tried. He cannot be convicted. Whatever he did on December 29, 1979, he died having never faced it. Kerryn Tate's sister Anne-Marie Tate said publicly: "I strongly urge anyone who's had even a slight suspicion about Terrence Fisher to please come forward to police." She is still asking. The family is still building the picture of who he was. So is WA Police. And the investigative genealogy team that identified him is still working. Kerryn Tate was 22 years old. She would be 68 today. This case, and this show, are for her. ECHO 1953 - THE HOLLIS FILES, BOOK ONE Available now on Amazon - Kindle, Kindle Unlimited, and paperback. Order your copy today.

This is the final series of the Midnight Mystery Archive — the last two-parter before the podcast goes on hiatus. It ends in Australia, one of MMA's largest listener bases, with a case that captures something essential about why this show existed: what happens when a young woman's life is cut short, and what forensic science can now do that nobody could have imagined when the crime occurred.

For 23 years, investigators and the public assumed the dark figure captured walking behind Trevor Deely on Haddington Road — 34 seconds after Trevor passed the camera — was the same man who had waited outside his office for 34 minutes in the rain. In December 2023, that assumption was definitively disproved.

An important update for every Midnight Mystery Archive listener. Kevin announced on social media Thursday, August 20th that MMA is going on extended hiatus. This episode is his direct message to the listeners — what happened, why, and what's still coming before the feed goes quiet. A major professional opportunity that Kevin has been working toward for years has arrived, and producing MMA at the level it deserves — 12 to 15 hours a week, every week — is not compatible with what comes next. The decision was not easy. But it was the only honest one. Before the hiatus begins: Trevor Deely Part 1 drops today. Part 2 drops next Friday. After that, a two-part Australian series. When that Part 2 lands, the hiatus officially begins. What MMA became in 16 months: 150 episodes. Over 100,000 downloads and YouTube streams combined. A goal of 5,000 downloads in the first year that was essentially doubled. Cases that deserved to be told, told the way Kevin wanted to tell them — thoroughly, accurately, and with the missing person at the center of every episode. The feed stays active. Kevin stays active on social media. And he holds out hope that when things settle, there's a path back. Thank you to every listener who shared an episode, left a review, sent a tip, or just showed up every Friday. It meant everything.

He was nine minutes from home. A man in dark clothing had been standing outside his office for 34 minutes before he got there. That was December 8, 2000. Trevor Deely has never been found.
