This is the story that started it all, the one where Dr Watson meets Sherlock Holmes for the first time and they move into 221B Baker Street. It’s a slightly clunky story in that the murderer is revealed half way through, then the background to the reasons why the murders were committed is provided, and then the confession happens at the end. Having said that, the version of the story I read is only 90 pages long, so it’s not a major inconvenience.
It’s interesting that Mrs Hudson isn’t mentioned in this book and that there are two Scotland Yard detective Lestrade and Gregson included. The book is recommended, though the American interlude in the middle is a slight distraction at least for me, but I admire the reasoning Sherlock gives for the deductions he makes so quickly and accurately.
