THE CRYSTAL-GAZERS

An alchemist- Barnabas Corwen- with an interesting collection of tallsman gems- holds a select seance which is rudely interrupted by the introduction of opium, and he is again the victim of more than a prank when he is deliberately electrocuted. The Yard, along with some assorted acquaintances of the dead man assist in the investigation which leads to the discovery- and disappearance- of a rare diamond. London, and thereabouts, the scene for some odd incidents and some very capricious characters. Unconventional, and a little unlikely.
