Echoes of Sherlock Holmes: Stories Inspired by the Holmes Canon edited by Laurie R. King and Leslie S. Klinger is a good collection of short stories.
The short stories in Echoes of Sherlock Holmes are not necessarily about Holmes. The authors were just asked to write a story inspired by Holmes.
I’m over half way through now and I’ll take a little break in reading this book now since I have other things to do but that is the good thing about short stores. You can read one or 2 at a sitting and put the book down for days or even weeks without a thought to losing the flow of the story.
I found some stories to be better than others but this is to be expected in anthology such as this.
