It is 125 years since Sir Arthur Conan Doyle's famous detective Sherlock Holmes and his sidekick Dr John Watson were introduced to the world.

The Sherlock Holmes Society has a current membership of almost 1,200 people from all over the world, and many of them spend their free time re-enacting the key moments of their hero's life.

More than 70 of them have just completed a pilgrimage to Meiringen in Switzerland, home of the Reichenbach Falls, and scene of the final struggle between Sherlock Holmes and his arch-enemy, the evil Prof James Moriarty.

The society's president Guy Marriott explained to BBC News why he and other enthusiasts travel the world dressed as characters from Holmes novels.
