Sherlock Holmes and the Devil's Grail

Sherlock Holmes and the Devil's Grail is a book by Barrie Roberts and was published in 1995.
== Summary ==
The uncharacteristically nervous great detective tackles the case of the tobacco millionaire and the Glastonbury Fragments, one of the most bizarre investigations of Holmes' and Watson's long partnership. In the spring of 1895, Colonel John Vincent Harman, an American inventor of an ingenious camera, was the object of anonymous threats to leave Britain, escalating to the abduction of his son, Jay. Behind this criminal activity, Holmes detected the hand of Drew, his old enemy, Professor Moriarty's lieutenant, an ex-Scotland Yard detective and worshipper of Demeter, the goddess of fertility. Drew suspected that Harman's stereoscope could uncover the mystery of a perverse religious cult, a priceless treasure which, if possessed, Moriarty believes, would give him power over the whole world.
