A young archaeologist risks everything in his quest to find one of the world\'s greatest treasures - the fabled lost library of Ivan the Terrible. It\'s a story that begins during the 15th century, and the sacking of Constantinople. The Ottoman Empire is approaching from the East, preparing to launch an all-out attack on the city. The Sultan rushes to save its most valuable treasures. The Library is its most valuable, and it\'s whisked away for safe keeping in Moscow. This was no ordinary library, but the greatest library outside of Rome. Records chronicled hundreds of carts laden with the rarest books, written by the world\'s greatest minds in history: Aristotle, Plato, Homer. These are reputed to be jewel encrusted tomes that hail from all parts of the globe. Ivan the Terrible\'s lost library became an obsession of Ignatius Stelletski, an archaeologist and historian. Its discovery would elevate him into the pantheon of history, and acquire wealth beyond his wildest dreams. In the early part of the 20th century he began to search the maze of underground tunnels lying beneath Moscow for the library. In 1914 he discovers a list that catalogues some of the more famous books in the library, including Aristotle\'s 2nd book of Poetics. The outbreak of World War One forces Stelletski to halt his work. Returning to his flat years later, the professor finds his home sacked, and the vital list gone. But his lifelong passion is undimmed. Stelletski continues undeterred to find the lost library, negotiating his way through all the political intrigue and villainy of 20th century Russia - the October Revolution, the rise of Stalin, and World War II. His search takes him under the Moscow Kremlin, in the Secret Gate to Zhitnev yard, in the bell tower of Ivan the Great Wall at Tseyhgauzskoy, the Round Tower, Borovitckii hill embankment of the Moscow River, and the Kremlin Arsenal Tower. Stelletski dies with the final words on his lips \"maktaba\", Arabic for library, with a tantalisi.

A lost treasure of immeasurable wealth - the riches of one of the most powerful empires in the history of the Americas - the Aztecs. Faced with annihilation at the hands of the Spanish conquistadors, Montezuma, the dying Aztec Emperor ordered his treasure trove spirited away and hidden. But despite torturing the Aztec leaders and mounting a vast number of expeditions, the Spanish conquistador Cortez still couldn\'t find it. For centuries Spanish adventurers would disappear into the hills and caverns of Mexico looking for it. But of course, the Aztecs ranged over a vast area. Many believed that if Montezuma had hidden the gold, it would be far from where the Conquistadors were hunting. Then In 1914, a man named Freddie Crystal walked down Main Street in Kanab, Utah, clutching a treasure map. He claimed that his map revealed the hiding place of King Montezuma\'s fabled Aztec treasure. When the outsider inquired around town, obliging locals informed Freddie that his map resembled a section of the White Cliffs 35 minutes south of the city limits. The clues to the whereabouts of the treasure lay in the graphic petraglyphs marked on the map. The same petraglyphs were etched on the cliffs around Kanab. To the amazement of the Mormons of small town Kanab, this stranger on a bike was telling them this vast horde of treasure was hidden near their town and there for the taking. 400 years after the death of Montezuma Freddie Crystal came in search for one of the biggest prizes in history. But was the treasure protected by an army of ghostly Aztec warriors and the curse of Montezuma?

Forensic pathologist Dr Philippe Charlier, known to the French as the \"Indiana Jones of the graveyards\" faced his biggest challenge yet: to uncover the truth behind the remains of France\'s most famous daughter - Joan of Arc. Joan of Arc, maid of visions and miracles, had achieved the seemingly impossible when she broke the military back of the English at the Siege of Orleans in 1429 to successfully see the Dauphin finally crowned Charles VII of France at Reims. But her subsequent capture by the English and trial at Rouen for witchcraft and heresy ended in her being sentenced to death by burning at the stake. In modern day France, Dr Philippe Charlier subjected these fragments to the full panoply of 21st century forensic analysis: mass, infrared and atomic-emission spectrometry; electron microscopy; pollen analysis and DNA analysis. One of the bones was not human but feline. Could it have been a cat burnt along with Joan? Black cats were often burned in the fire of those reputed to be witches. But, its origin was not even European. Charlier found nothing in the organic material that matched anything that would have existed in 15th Century Burgundy. In a final, stunning confirmation: carbon dating placed the fragments of bones between the 7th and 8th Century BC. This was no Joan of Arc, this was an Egyptian Mummy! Black tar-like coating on the fragments had nothing to do with burning, but rather embalming. Somehow an Egyptian mummy had ended up being in an apothecary\'s jar labelled as the remains of Joan of Arc. Yet may hold the belief that the remains of Joan of Arc are still to be found, and returned to a place of honour.

Six recession-hit patriots from Oregon stake everything on mining and head north to Alaska to dig for gold and save themselves from financial ruin. The team of greenhorns beg, borrow and build all the equipment they need to mine for gold. Loaded with supplies, they leave their loved ones behind and drive from Oregon to southeast Alaska in a Klondike convoy.

The stakes get higher at the Porcupine Creek prospect as reality sets in about just how little time they have to get to their gold. The miners start to rebuild the mining ghost town but the bears aren\'t so keen on their new neighbors — and they let them know it.
