Who was the Mothman? What caused the death of the Bordens? Who assassinated JFK? And what was the true meaning of the 'WOW' signal? Daniel Smith, author of 100 Places You Will Never Visit, sets out to uncover the truth behind 100 unexplained events that have been shrouded in secrecy for generations. Under his investigative searchlight are mysterious landmarks, disappearances at sea, legendary myths, astonishing coincidences, UFOs, missing people and bizarre natural phenomena.

Ranging from suspicious deaths (Black Dahlia) to suspected murderers (Jack the Ripper) and from ancient artifacts (Tarim Mummies) to Cold War cover-ups (Lost Cosmonauts), via documents that remain untranslatable (Voynich Manuscript), debated icons of religion (Shroud of Turin), and puzzling paranormal appearances (Marfa Lights), Daniel Smith leaves no stone unturned in his quest to expose the bare facts and reveal the truth amongst the tales that have gripped curious minds for years.

Also includes: Bermuda Triangle, Red Rain, Collapse of the Mayan Civilisation, Spontaneous Combustion, Whereabouts of Nazi Gold, Disappearance of Jean Spangler, Severed Feet of British Columbia, Shakespeare's Dark Lady, Shugborough Inscription, Stonehenge, Loch Ness Monster, The Flying Dutchman, Lewis Carroll's Lost Diaries, and the Beast of Bodmin Moor.
