Mystery!: Unsolved Crimes

Sometimes crimes are committed that never get solved and so they remain a mystery. Delve into the facts behind some of the world's most mysterious crimes including murder, theft and missing persons to find out what we do know about these cold cases and what the possible explanations could be. 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.
