Unusually, Sherlock Holmes goes to Paris, without notifying Dr. Watson, while a few days before, his shoe and a precious diamond, once in possession of Irene Adler, appeared at the Louvre Museum.

On the one hand, a diplomatic conflict broke out over the ownership of that diamond between: France, Great Britain, Switzerland, the Netherlands and Spain. And on the other hand, Sherlock Holmes aspires that this jewel will serve to capture and silence Irene Adler, who is blackmailing him with a terrible family secret.

Sherlock Holmes corners Irene Adler in his hotel room in Paris, but she commits suicide...
