Séances, mental telepathy, telekinesis-these are just some of the alleged phenomena described in this entertaining volume. Some have been hoaxes, others have yielded natural explanations, but a few remain as true mysteries.

This imaginative series looks at great mysteries of the past that can be explained by science today. It also covers more recent events, many of which remain unexplained. This book tells the stories, shows photographic evidence, discusses theories-and balances the account with "Professor Skeptic," who offers opinions and provides explanations that account for both hoaxes and entirely natural phenomena.
