In 1708, during the War of the Spanish Succession, the Spanish galleon San José sailed from South America carrying a vast cargo of gold and silver bound for Spain. Off the coast of present-day Colombia, British ships of war intercepted the galleon in a fierce naval clash. During the battle, the San José exploded and sank, taking its enormous treasure to the bottom of the Caribbean.

My guest this week is Julian Sancton, author of Neptune’s Fortune: The Billion-Dollar Shipwreck and the Ghosts of the Spanish Empire. He discusses the circumstances that led to the sinking of the San José and enigmatic Cuban archaeologist Roger Dooley’s determined quest to locate the wreck deep beneath the sea.

(Orig. Pub Date: 11/10/21) In January of 1923, a 20-year-old dancer named Fritzie Mann left home to meet a mysterious man for what she told her mother was a house party. When she was discovered dead on a remote beach a few miles north of San Diego, police were puzzled by the clues. Was it an accident, suicide, or murder? The fact that she was pregnant deepened the mystery even further. Soon two men – a Hollywood actor and a doctor – became the primary suspects in the case, and one would eventually be put on trial for murder.

My guest is James Stewart, author of “Mystery at the Blue Sea Cottage: A True Story of Murder in San Diego’s Jazz Age”. He shares details about strange death of Fritzie Mann, considered by some to be San Diego’s very own Black Dahlia, and offers intriguing theories on what might really have happened to her.

In 1949, a quiet neighborhood in St. Louis became the center of one of the most controversial religious cases in American history. A 13-year-old boy began exhibiting disturbing symptoms including violent outbursts, strange markings on his body, and other troubling episodes, leading Catholic priests to perform a series of secret exorcism rites. The case would later inspire The Exorcist, but the real story was far more complex than the film.

My guest is Troy Taylor, author of The Devil Came to St. Louis: The Uncensored True Story of the 1949 Exorcism, who takes a careful look at the case, its origins, and how fact, faith, and folklore became intertwined in one of America’s most enduring mysteries.

Told and retold in many languages, the legend of the Blood Countess has consumed cultural imaginations around the world. But despite claims that Elizabeth Báthory tortured and killed as many as 650 girls, some have wondered if the Countess was herself a victim- of one of the most successful disinformation campaigns known to history. So, was Elizabeth Báthory a monster, a victim, or a bit of both?

My guest is Shelley Puhak, author of the new book "The Blood Countess: Murder, Betrayal, and the Making of a Monster". She helps us separate fact from fiction as she reexamines the life of Elizabeth Báthory, long labeled one of history’s most notorious killers, and unpacks a complex story of power, politics, and how it all led to the making of a "monster".

On a beautiful fall day in September 1916, 68-year-old Hannah Spielman went on a picnic with her new husband, 71-year-old James Allen, in the woods outside Grand Rapids, Michigan. She had met him through a newspaper advertisement, and the two were married just two days earlier - only hours after stepping off a train and meeting him face-to-face for the first time.

But James Allen was not the man he claimed to be. His real name was Henry Scott Mausell, and his intentions were anything but honorable. Eleven days later, Hannah’s decomposed body was discovered and the murder investigation began.

So who was Henry Scott Mausell? A man with a deeply troubled past—and Hannah was likely not his first victim, but the last in a long line of murdered women. In "Bloodstained: Exploring Michigan’s Darkest Murders Forgotten by Time", author Allie Seibert sheds light on this largely forgotten, and very likely, serial killer.

On October 21, 1836, crowds lined the docks of Saint John, New Brunswick, to watch the steamship Royal Tar depart for Portland, Maine - this time carrying an entire circus. Cages filled with exotic birds, snakes, lions and a tiger rolled on board, along with horses, camels and the star attraction: Mogul, a massive Asian elephant, who took his place on the upper deck. Four days later, after battling fierce storms, the ship caught fire, killing many on board. In desperation, some animals were forced into the icy waters of Penobscot Bay, while others perished in their cages.

My guest is Jane Parks Gardner, author of The Wreck of the Circus Ship Royal Tar: Tragedy in Penobscot Bay. She shares details on the disaster, and its impact on Maine’s maritime history.

At the close of the nineteenth century, serial killer Joseph Vacher terrorized the French countryside for years, eluding capture while murdering more victims than Jack the Ripper.

My guest is Douglas Starr, author of "The Killer of Little Shepherds: A True Crime Story and the Birth of Forensic Science". He shares details with us about Vacher’s reign of terror and the groundbreaking investigation that led to his conviction.
