There are phenomena we will never understand, and experiences we believe we understand but do not. Not everything follows the rules of logic, and not everything can be deduced from cause and effect. Cryptozoology, parapsychology, uncaught killers, paranormal activity, extraterrestrials, forgotten history, and all types of fringe science fill the pages of Unsolved Mysteries. You'll find information on:  Mysterious ancient practices, like trepanation, the 7,000-year-old practice of drilling holes into the skull to purportedly treat tumors, infections, and mental health problems Chilling anecdotes about unsolved murders that shook the public, like the infamous Black Dahlia and Lizzie Borden murders Spooky folklore, urban legends, and tall tales, from Bigfoot, Sasquatch, and Mothman, to Ohio Bridge Trolls, Maryland's Goatman, and Gatormen Enigmatic people throughout history, like Nostradamus and Rasputin Unexplained phenomena that have fascinated observers for decades. Do you believe in UFO's, aliens, and ghosts? 272 pages
