Objects can carry romantic myths, embody dangerous curses, or provide links to our past. Some mysterious items, like the Hope Diamond, can still be found today, while others, like the Philosophers' Stone, have vanished into the mists of time. Gifted and sensitive psychometrists can apparently pick up an object and learn many things about its past and its previous owners. The World's Most Mysterious Objects provides a glimpse into these enigmas, exploring everything from psychic weapons and spiritual icons to alchemical experiments and strange devices. With this intriguing book, find out what secrets the world could be hiding.

Castles are among the most mysterious buildings on earth. Their grimly silent stones are signposts to a past filled with high adventure, grim tragedies, and glorious victories. Ghosts, hauntings, and other paranormal phenomena are frequently reported from castles. Do strange paranormal powers lurk among their ancient ruins? The World’s Most Mysterious Castles takes you on a journey through hidden chambers and subterranean tunnels of castles all over the world. Their walls served the sinister needs of spies, traitors, and assassins. Do the spirits of attackers and defenders who died in long-forgotten sieges still linger where they fell? Screams of unbearable pain and despair were muffled within their deepest, darkest torture dungeons. Do they echo there still?

Reading of murder stimulates a powerful response. We are repelled by the horror of it, but, simultaneously, our natural curiosity is strongly aroused. We want to know who did it, and why. Most unsolved murders have no apparent motives - or too many motives. The murders of Sir Harry Oakes in 1943, one of the richest men in Canada, and Christine Demeter, found dead in a blood-soaked garage in Mississauga in 1973 - remain unsolved. In fact, history is full of unsolved murders. Who killed King William Rufus, Edward II, and the Princes in the Tower? Who was Jack the Ripper? Was James Hanratty really guilty of killing Michael Gregson? These mysteries and more are contained in The World’s Most Mysterious Murders.

A fascinating compilation of stories about lost lands, weird locations, and strange sites.
