Enter the fascinating world of the unexplained with a range of mysterious happenings, disappearances and visitations.
Sometimes people and things just disappear, but how and why? Delve into the circumstances behind some of the world's strangest vanishing acts. Have people really vanished in the Bermuda Triangle and what is so odd about the disappearance of the Mary Celeste? Find out what we do know and what we don't about these incredible mysteries.
Real (and possibly not so real) unexplained events are examined in the four books in this series. Strange disappearances, alien visitors, mythical creatures, messages from beyond the grave and strange places steeped in mystery all make an appearance (or should that be disappearance?!) in these fun and informative books.
