As the 21st century marches into its third decade, our understanding of the world, and our place within it, seems to be clearer than ever. Each day brings us more and more miraculous scientific discoveries, while technology has interconnected us to an extent that our ancestors and forefathers could not have conceived. And yet, despite the collective of human knowledge lying at our fingertips, there are still a multitude of unsolved mysteries that stubbornly resist any attempts at solving them.

Contained in this volume are just a few of the many, many unsolved mysteries that still haunt both skeptic and believer even in today’s “modern” age. These mysteries include both classic cases from farther back in the past and a few more recent ones that have haunted the supposed golden age of the 21st century.

Among these mysteries are some of the most chilling cases of missing persons that have occurred over the past few decades. Explore the maritime nightmares within the cases of Amy Lynn Bradley and Rebecca Coriam, for whom idyllic tropical cruises turned into baffling tragedies when both women went missing at sea without a trace. Scratch your head at the seemingly impossible disappearance of Brian Schaffer, who was seen entering a crowded bar one night but never seen leaving. Follow the leads in the sinister vanishings of Jodie Huisentruit, Ben Needham, and Renata Antczak, whose disappearances hint at darker crimes, obsessions, and cover-ups.

You can then place yourself in the shoes of a grizzled detective as you follow along with the criminal investigations of some of the most disturbing and gruesome unsolved crimes of the 20th century. Profile a rogue's gallery of potential suspects in the horrific murder and mutilation of the young and beautiful Elizabeth Short - aka the "Black Dahlia". Join famed lawman Elliot Ness as he pursues the darkest and most difficult case of his storied career - the faceless psychopath known by the grisly moniker the "Cleveland Torso Murderer”. Walk through the snowy ground of an isolated Bavarian farmstead as you explore the terrifying mass killing of an entire family during the infamous Hinterkaifeck killings.

Then, turn your attention to the skies as we examine some of the most notorious and intriguing UFO sightings to have occurred in the 21st century; sightings that have spanned both the isolated American Southwest and the heavily-populated areas around New York City and Chicago. And finally, explore the truth behind some of the most authentic UFO footage to come out in decades, the sightings that baffled the mighty United States Navy and forced the American military to, for the first time, officially acknowledge the existence of UFOs.

Among these disappearances, unsolved crimes, strange phenomena, and even lingering historical mysteries, you can listen to all details and theories and decide for yourself what you want to believe or not. These cases - and more - will astound, intrigue, and unsettle you and, more than anything else, leave you with a lasting impression that there might be more to our world than first meets the eye.
