In the summer of 1913, the wooden-hulled brigantine Karluk departed Canada for the Arctic Ocean. At the helm was Captain Bob Bartlett, considered the world’s greatest living ice navigator. The expedition’s visionary leader was a flamboyant impresario named Vilhjalmur Stefansson hungry for fame. Just six weeks after the Karluk departed, giant ice floes closed in around her. As the ship became icebound, Stefansson disembarked with five companions and struck out on what he claimed was a 10-day caribou hunting trip. Most on board would never see him again.

On January 28, 1742, a ramshackle vessel of patched-together wood and cloth washed up on the coast of Brazil. Inside were thirty emaciated men, barely alive, and they had an extraordinary tale to tell. They were survivors of His Majesty’s Ship the Wager, a British vessel that had left England in 1740 on a secret mission during an imperial war with Spain. While the Wager had been chasing a Spanish treasure-filled galleon known as “the prize of all the oceans,” it had wrecked on a desolate island off the coast of Patagonia.

September 29, 1913: the steamship Dresden is halfway between Belgium and England. On board is one of the most famous men in the world, Rudolf Diesel, whose new internal combustion engine is on the verge of revolutionizing global industry forever. But Diesel never arrives at his destination. He vanishes during the night and headlines around the world wonder if it was an accident, suicide, or murder.

The small ship making the Liverpool-to-New York trip in the early months of 1856 carried mail, crates of dry goods, and more than 100 passengers, mostly Irish emigrants. Suddenly, an iceberg tore the ship asunder, and five lifeboats were lowered. As four lifeboats drifted into the fog and icy water, never to be heard from again, the last boat wrenched away from the sinking ship with a few blankets, some water and biscuits, and 13 souls. Only one would survive. This is his story.

When the once-mighty city of Rome was sacked by barbarians in 410 and lay in ruins, it signaled the end of an era—and the beginning of a thousand years of profound transformation. In a gripping narrative bursting with big names—from St Augustine and Attila the Hun to the Prophet Muhammad and Eleanor of Aquitaine—Dan Jones charges through the history of the Middle Ages. Powers and Thrones takes listeners on a journey through an emerging Europe, the great capitals of late Antiquity, as well as the influential cities of the Islamic West.

The reporters said it was a sexy story-church, money, greed, adultery, blood, a defenseless child with profound disabilities, and a good man who never saw it coming, all the elements that garnered column inches and high ratings. The main players on the stage included a talented journalist who played the organ at church, a cunning narcissist who hid behind a pretty face and a sweet demeanor, and a respected businessman and father.

John Edward Robinson was a 56-year-old grandfather from rural Kansas. An entrepreneur and Eagle Scout, he was even honored as "Man of the Year" at a Kansas City charity. To some of the women he met on the internet, he was known as Slavemaster - a sexual deviate with a taste for sadomasochistic rituals of extreme domination and torture...even killing.

By 1930, no place in the world was less well explored than Greenland. The native Inuit had occupied the relatively accessible west coast for centuries. The east coast, however, was another story. In August 1930, Henry George Watkins (nicknamed “Gino”), a twenty-three-year-old British explorer, led thirteen scientists and explorers on an ambitious expedition to the east coast of Greenland and into its vast and forbidding interior to set up a permanent meteorological base on the icecap, 8,200 feet above sea level.

Schoolteacher Olivia Dare Christian was murdered in her Hampton, Virginia, apartment in 1981. Her killer left few clues and the murder went unsolved. Three decades later, in 2011, next-generation detective Randy Mayer re-opened Olivia's dusty cold case file and began unraveling the mystery. Mayer located a reluctant witness who was a teenager back in 1981. She recalled a suspicious man lurking outside Olivia's apartment the morning of the murder and provided a detailed description of the man.

On May 1, 1915, with WWI entering its tenth month, a luxury ocean liner as richly appointed as an English country house sailed out of New York, bound for Liverpool, carrying a record number of children and infants. The passengers were surprisingly at ease, even though Germany had declared the seas around Britain to be a war zone. For months, German U-boats had brought terror to the North Atlantic.

The Last Viking unravels the life of the man who stands head and shoulders above all those who raced to map the last corners of the world. In 1900, the four great geographical mysteries - the Northwest Passage, the Northeast Passage, the South Pole, and the North Pole - remained blank spots on the globe. Within twenty years Roald Amundsen would claim all four prizes.

In his early thirties Justin Alexander Shetler quit his job at a tech startup and set out on a global journey: across the United States by motorcycle, then down to South America, and on to the Philippines, Thailand, and Nepal, in search of authentic experiences and meaningful encounters, while also documenting his travels on Instagram. His enigmatic character and magnetic personality gained him a devoted following who lived vicariously through his adventures.

For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe—and extend their colonial empires.

These are the stories that defy conventional logic. The proverbial vanished without a trace incidences, which happen a lot more (and a lot closer to your backyard) than almost anyone thinks. These are the missing whose situations are the hardest on loved ones left behind. The cases that are an embarrassment for park superintendents, rangers, and law enforcement charged with Search & Rescue.

In 1803, President Thomas Jefferson selected his personal secretary, Captain Meriwether Lewis, to lead a voyage up the Missouri River, across the forbidding Rockies, and - by way of the Snake and the Columbia rivers - down to the Pacific Ocean. Lewis and his partner, Captain William Clark, endured incredible hardships and witnessed astounding sights. With great perseverance, they worked their way into an unexplored West. When they returned two years later, they had long since been given up for dead.
