The Adventure of The Speckled Band (Unabridged‪)‬

"The Adventure of the Speckled Band" is the 8th of 12 stories collected in
The Adventures of Sherlock Holmes. It was originally published in
Strand Magazine in 1892. Doyle thought that this was his best Holmes story. In fact, he thought so much of it that he wrote and produced a play based on the story. The play, originally called "The Stonor Case," differed from the story in several details but was essentially the same.
