In London in 1888, the greatest mystery writer of all time, Sir Arthur Conan Doyle, author of the Sherlock Holmes mysteries, met the greatest mystic of the nineteenth century, Madame Helena Blavatsky, a Spiritualist who claimed the ability to communicate with the dead.  

 

Three years later, shortly after Blavatsky's death, a curious wooden box arrived at Doyle's Windlesham Manor estate in East Sussex.  There was no note.  But engraved in brass on the lid were these words:  "For A.C. Doyle -- Compliments of Madame Blavatsky."

 

Would you like to know what was inside the box?   Shall I tell you now?
