Unexplained phenomena have been written and spoken about for centuries. Science has rationalised some things but many mysteries still remain unsolved. Is spontaneous human combustion real? Can a person burn from the inside outwards until all that remains of them is a pile of ashes (and maybe a charred arm or leg)? Did ancient alien astronauts visit earth thousands of years ago and leave behind secret messages and amazing feats of engineering like Stonehenge? Do UFOs exist or are they optical illusions? Using thrillingly written accounts and storyboard presentations, this fascinating collection of case files covers everything from crop circles to monsters with a view to examining and evaluating the evidence... so you can make up your own mind. Not everything you read is true and learning how to discriminate and assess the real facts is a useful, if not essential, skill for all youngsters to learn.
