Novedad de próxima aparición, de uno de los prolíficos autores que publican en Titan y de los que aquí podéis encontrar anteriores entregas.
The aristocratic Charles Bromley arrives at 221B Baker Street to beg the great detective for his help. Bromley believes that his wife is in danger, as she has refused an offer to sell the Moonstone, a fabulous diamond that has been in her family for generations, but which is said to be cursed.
When a jeweller is found murdered, it seems as if the Moonstone deserves its reputation. Then the diamond is stolen, and Holmes and Vernier must try to unravel a mystery centuries in the making.
