This is a group of Doyle's short stories. It's more varied than many of the collections of his works. The stories are set in countries around the world and are many different genres. It includes
The Gully of Bluemansdyke - It's not so much a mystery as a tale of justice and vengeance. It's good. I just wish he'd expanded it to a novel instead of leaving it a short story.
The Parson of Jackman's Gulch - That one is fun. Rather unexpected after the beginning story.
And:
My Friend the Murderer
The Silver Hatchet
The Man from Archangel
The Little Square Box
A Night Among The Nihilists
