Story: 4 stars. The story, told entirely from Sherlock Holmes' POV, starts with John Watson's funeral after which Holmes returns to Baker Street and ruminates about his past and about the cases and adventures he shared with his friend. Bits and pieces from Doyle's work are used and explained from Holmes' POV, like "The Speckled Band" or "The Hound of Baskervilles". The story is incredibly touching, especially when Holmes forgets that Watson's not there and just turns to where his friend should be to tell him something funny or interesting and just... stops. You literally feel just how much Holmes loved his friend - in this the story reminds me of Anthony Horowitz's "The House of Silk". On the other hand, some of the stuff borrowed from Doyle is just too long and the part about Holmes' childhood - though interesting - feels a bit off, it jars, this transition from commonly known cases to something entirely new.
Narration: 2 stars. Well. As Roger Llewellyn himself admits in the interview at the very end, he's not a character actor. And I simply didn't like the way he read the story. I understand that he needed to set the various characters apart, but sometimes I could barely understand him and... well, let's just say that in some places, his reading was so full of pathos it was laughable, not dramatic. If I had been the director, I would've asked him to tone it down. It really affected my enjoyment of the story.
Overall? A really good story - David Stuart Davies is a fantastic Sherlock Holmes author - but I would've preferred to read it myself instead of listening to it.
